How to Grow Magnolia Grandiflora (Southern Magnolia Trees)
The southern magnolia (Magnolia Grandiflora) is a beautiful, adaptable evergreen tree known for its large, fragrant, white flowers and lustrous dark green leaves that grow on the conical crown. The fall fruit will attract birds to your landscape.
It isn't the largest species, typically growing up to 60 to 80 feet tall, but it has a dense canopy and a shallow root system. The tree needs plenty of space, requires mulch to prevent erosion problems, and it isn't a good choice if you want to grow underneath it. Plant these trees in late spring or early fall, and be aware it can take 10 to 20 years for them to reach their full size.

Magnolia Grandiflora Care
Southern magnolias are attractive and relatively easy-to-grow specimen trees—just be sure to select a site that is sheltered from strong winds and offers them ample room to grow. Plant your magnolia tree in the ground in a hole at least as deep as its root ball. Dig the hole around the plant to leave room for it to grow about twice the size of its original pot. Moist, well-drained soil is best, but this species can thrive in a variety of conditions.
These magnolias are often planted in rows to act as a privacy screen or to define property lines. Because of their messy leaf drop in the spring and fall, they aren't always a good choice for a lawn. Planting in an ornamental bed means you can use the robust leaf debris can as a natural mulching material.
You can plant container-grown trees at any time (although avoid planting in the heat of summer), and those bought balled and burlapped are usually transplanted sometime between August and October. Transplant shock is common with this species, so don't worry if the tree sheds many leaves during its first growing season.

Southern Magnolias do best in partial shade, particularly if soil conditions aren't all that moist. Once established, they can do well in a full sun position in moist, rich soils. Ideally, your tree should receive at least four hours of unfiltered sunlight a day. In nature, southern magnolia is an understory tree, so it tolerates shade, although it needs sun to bloom well.
Southern magnolias do best in moist, well-drained, loamy, acidic, and fertile soils. However, they can tolerate a wide range of conditions and pH levels. Overly dry or prolonged waterlogged conditions and high alkalinity aren't appreciated.
Providing your southern magnolia has ample room for root expansion and the soil is not a poor, dry type, it will demonstrate drought tolerance.
When first planted, the tree will need weekly watering to become established. Once established, water frequency will depend on soil drainage and regional rainfall. Too much or too little water can cause the tree's leaves to turn yellow. Mulching around the planting area is beneficial—just avoid allowing the mulch to touch the tree's trunk.
Temperature and Humidity
Southern magnolias prefer temperate and humid semitropical climes. Extremes of temperatures are not good, and even a light frost easily damages seedlings.
Fertilizing three times a year—in spring, summer, and fall—is beneficial once your southern magnolia starts to produce new growth. By the fourth or fifth year, unless your tree is in particularly infertile soil, its sprawling roots should be able to find sufficient nutrients themselves.
Types of Magnolia Grandiflora
The southern magnolias popularity means there are many cultivars, with some that flower early and others with a smaller growth habit or thicker canopy. Some popular examples include:
- Magnolia grandiflora 'Edith Bougue': One of the most cold-hardy cultivars, it has a pyramidal form that grows tighter and denser as it ages, and it typically reaches up to 30 feet tall.
- Magnolia grandiflora 'Hasse': With its tight, columnar form, this cultivar works well for use in smaller spaces or in rows for screening. It typically reaches up to 40 feet tall.
- Magnolia grandiflora 'Little Gem': This award winner is an excellent option if you are looking for a dwarf magnolia. One of the smallest cultivars, it is typically grown as a shrub and doesn't often grow higher than 25 feet. Although the leaves and flowers are small, they are still attractive, and the tree blooms abundantly from a young age.
If you want to tidy up your southern magnolia, encourage a tight, compact form, or give it a more tree-like appearance, you can prune it after the blooming season is over. Do this before winter—dormant magnolia branches don't heal easily. Avoid pruning the lower limbs to allow a more open and natural form and to prevent disease-inducing stress and suckers from forming.
Propagating Magnolia Grandiflora
It is possible, but sometimes tricky, to propagate southern magnolia from cuttings. If you plan to try this, there is some general guidance to be aware of:
- Select a six-inch semi-hardwood cutting with at least a few leaves from young stock during the summer months. make a straight cut above a node. Remove any lower leaves.
- Apply a rooting hormone to improve success rates
- Place in a moist, well-drained rooting medium that is at least 4 inches deep
- When transplanting the cutting, take care not to damage the fleshy and delicate roots
How to Grow Magnolia Grandiflora From Seed
If you want to grow a southern magnolia from seed, try these tips:
- Collect ripe cones from an existing tree. Dry until the fleshy fruits come away freely. Soak the seeds in warm water for 1-2 days to remove the seed coating. Once the coating has softened, drain off the water.
- Clean and dry the seeds with tissue. Either sow the seeds fresh and overwinter in a cold frame, or mix with moist peat, vermiculite, or sand, place in a plastic bag, and refrigerator for two months before sowing.
- Germination can take up to 18 months.
- When the seedlings are large enough to handle, move them into a light shade position. Keeping them in a cold frame or greenhouse for their first full winter is beneficial.
- Plant out when the seedlings are at least 6 inches tall, mulch well, and protect for the first couple of winters.
Common Problems With Magnolia Grandiflora
Southern magnolia are known for being relatively pest and disease-free. However, if conditions are not right, problems are possible.
Certain fungi and bacterium can cause leaf spots and blights. These include Septoria spp, Cladosporium spp, and Coniothyrium spp. Although it can look unsightly, they don't often cause any major damage. Promptly clearing away infected fallen leaves can help to control the problem.
Canker diseases and Verticillium wilt can kill off branches. Manage this by pruning out the problematic branches and ensuring the tree is healthy, well-nourished, and watered.
Magnolia Tree: Plant, Grow and Care for Magnolias
Magnolias are beautiful shrubs and ornamental trees that bring a touch of show-stopping glamour to the garden. Their sumptuous, tulip- or star-like flower colours range from pure white through pink to deep magenta and even yellow. Many also have a lovely fragrance.
Magnolias can be deciduous or evergreen, and range in size from small shrubs to large trees. Most prefer neutral or acidic soil. If you don't have the right type of soil, the smaller magnolias grow well in pots. Many flower in spring, but some flower in summer.
Magnolia trees and larger shrubs are ideal for growing as standalone trees, while the smaller magnolia trees such as Magnolia stellata look good in a border or make good trees for pots. Read more about trees for small gardens. Evergreen magnolias, such as Magnolia grandiflora, can be trained against a wall.
A magnolia bush or tree is a long-term investment – they are slow growing and can take 10-20 years to reach their ultimate size. It's therefore worth taking the time to choose the right variety for your garden. The flowers, ultimate size and the conditions in your garden will determine which magnolia you grow. If it's happy, it will thrive and reward you with a fantastic display of flowers.
How to grow magnolias
Most magnolias do best in acidic to neutral soil. If you don't have the right soil in your garden, or don't have room for a large tree, the smaller magnolias grow very well in pots. Magnolias need a sheltered spot, away from strong winds. Avoid frost pockets, as frost can damage the flowers in spring. A spot that gets plenty of sun will ensure a good display of flowers. Prune lightly in mid-summer to early autumn. Ensure the soil does not dry out in summer.

How to grow magnolias - Magnolia sprengeri 'Diva'
Magnolias grow best in fertile, well-drained, slightly acidic soil in full sun. Choose a sheltered spot that is not in a low-lying frost pocket – frost can damage the flowers. If you live in a cold part of the country, choose a variety that flowers later. Bear in mind the eventual height and spread of the tree and make sure that you have allowed room for it – some magnolias can grow very large. If you're concerned about growing a magnolia near the house, opt for a small magnolia tree. If you have alkaline soil, grow Magnolia grandiflora or Magnolia delavayi.
How to plant magnolias
Magnolias are best planted in autumn or late spring. They have shallow roots, so you don't need to dig a very deep hole. Dig a generous hole to the same depth of the pot your magnolia comes in. Avoid damaging the fleshy roots, as this can inhibit flowering. Add well-rotted garden compost or leaf mould around it, and check the level of the plant so that the point where it has been grafted is not below the soil. Gently firm in the plant with your heel and water in well. Mulch with an acidic mulch such as bark, or garden compost. Keep the plant well watered while it establishes.

Pruning magnolias is best done after they has flowered, to remove broken, diseased or crossing branches. Magnolias don't respond well to hard pruning and may cease flowering afterwards. So if you do have to restrict the size of your shrub or tree, or renovate it, do this over a few years, pruning only a few branches at a time to avoid stressing it. Mulch in spring with manure, composted pine bark or leaf mould. Ensure that the plant does not dry out in summer.
How to propagate magnolias
Magnolia shrubs are propagated by layering.
Magnolias can be propagated by cuttings, but they may need extra heat and light in winter. Deciduous magnolias can be propagated by taking softwood cuttings in early summer and evergreen varieties by semi-ripe cuttings in late summer and autumn.
Growing magnolias: problem solving
The most common problem when growing magnolias is a lack of flowers. Young magnolias can take several years to flower, so be patient. Make sure you have the right soil – neutral to acidic, not alkaline – and the right spot. Magnolias need plenty of sunshine and shelter from strong winds and frosts, which can damage the flowers. Heavy pruning in summer will remove the developing flower buds and will also stress the tree, preventing it from flowering. Lack of water can also stress the tree.
Blackened foliage is due to frost damage. New magnolia leaves should resprout when the weather warms.
Catherine Mansley from BBC Gardeners' World Magazine explains why magnolias may not always flower and how to encourage them to do so, in our Quick Tips video:
Magnolias rarely suffer from pests, but can be prone to a few fungal diseases.
Honey fungus can spread underground and attack and kill the roots of magnolia, eventually killing the plant. Symptoms to look out for include die-back, pale foliage, an absence of flowers, bleeding and cracking bark.
Phytophthora root rot can cause similar symptoms to honey fungus, including sparse foliage and dieback. It can be a problem on heavy or waterlogged soils.
Bracket fungus also causes dieback, as well as thinning of the tree crown. You will also spot large fungi on the branches of the trees. By the time these appears, there will have been extensive decay in the heart of the branch, which may fall off.
In all three cases, there is little you can do. You may need to dig up the plant and the surrounding soil, and replace with a different shrub or tree that is less prone to fungal problems.
Advice for buying magnolia
Here's our guide to buying a magnolia for your garden, including how to choose and where to buy:
- Magnolias are available in garden centres and nurseries, as well as specialist nurseries. Bear in mind that you will get a better selection at a specialist nursery
- Check that you have the right conditions to grow a magnolia. Most need slightly acidic soil to thrive. A good rule of thumb is to check whether magnolias are growing in front gardens in your area
- Bear in mind that your plant may take several years to flower. Many are sold on a grafted rootstock, and should flower after three to five years
- If you live in a frost pocket or in the north of the UK, choose a variety that flowers in late April or May, to avoid frost damage to the buds. Varieties include 'Caerhays Surprise' and 'Apollo'
- Research the ultimate height and spread of your magnolia. Although they are slow growing, taking 10 or even 20 years to reach their ultimate height, you need to bear this in mind when buying
- Buy as mature a plant as you can afford – it will establish better. Add plenty of organic matter when planting and do not let the plant dry out in summer

Magnolia: planting and care, outdoor cultivation
Flowering magnolia plant from the Magnolia family unites more than 200 species. The plant was first brought to Europe in 1688. Archaeologists have recently discovered a fossilized magnolia flower that is over 95 million years old. This is one of the oldest cultures on the planet, which easily adapts to the surrounding climate. Under natural conditions, the plant can be found in Asia and East America, in the tropics and subtropics. Magnolia got its name in honor of the French scientist and systematizer of botany Pierre Magnol.
Bouquets containing magnolia branches are rare, but they look very impressive and aristocratic. If you are looking for original flowers in Zaporozhye, rather look into our catalog, where you will find many unusual compositions.
Magnolia can be a deciduous tree or evergreen shrub with brown, smooth or scaly bark. The plant reaches a height of 5 to 20 m. On the shoots, you can see scars from leaves and stipules in the form of a ring. The kidneys are large, leathery, green with veins. The leaves are usually ovate or elliptical in shape. The flowers are decorative, bisexual and very fragrant. They grow up to 35 cm in diameter and come in white, pink, lilac or purple. Flowers consist of 7-12 elongated petals, which are tightly adjacent to each other and arranged in several rows. Most species begin flowering in early spring, but some late varieties bloom in summer. The fruit is a leaflet in the form of a cone, with a large number of seed leaflets. The seeds are triangular, with a fleshy seed. After opening the petal, the seeds seem to hang on the threads.
Blooming magnolia is one of the most beautiful plants in the garden. In addition to its beauty, the plant has a number of healing properties. A large amount of essential oils is concentrated in fruits, flowers and leaves. Oils are used for antiseptic purposes and in the treatment of chronic diseases such as hypertension and rheumatism. The product is a natural aphrodisiac and increases sexual desire in women and men. Magnolia essential oils are widely used in the perfume industry. In aromatherapy, oil is used to eliminate the symptoms of stress, fatigue and disorders of the central nervous system. There is a sad and instructive parable about the origin of magnolia. According to legend, a Japanese girl named Keiko made a living making paper flowers. And then one day, her pet parrot said that if you put a drop of your blood on paper, the flowers will become alive and they can be sold for much more. The girl obeyed her pet and began to get rich quickly. However, her greedy lover demanded more and more money every day in order to live in luxury. And then one day the girl simply had no strength left, and she gave her last drop of blood. The flower that appeared after that was called magnolia and since then it has symbolized selflessness and generosity.
Types and varieties of magnolia
Breeders have worked hard to develop varieties of magnolia that are suitable for growing in the middle lane. The largest collection of magnolias was collected in the UK - in the Royal Botanical Garden. There are frost-resistant, conditionally winter-hardy and exotic species. Varieties that grow up to 15-30 meters are not well suited for garden design. Many types of magnolias get along well with conifers, most of them require timely sanitary pruning. Some frost-resistant varieties, with proper care, can grow even in Siberia. The most common are large-leaved, virgin Sulange and lily-colored magnolia.
Spectacular magnolia native to Japan. Breeders note the extremely high decorativeness of this tree or shrub. Leaves grow up to 12 cm long, flowers up to 10 cm in diameter, white. This species has 2 forms: kei and pink. Various hybrids of the plant are very popular, such as magnolia Anna, Jane and Susan.
Tropical magnolia, which is used to the harsh conditions of Eastern Europe. This is either an evergreen tree up to 23 m in height, or a shrub that grows up to 10 meters. In the US, the tree blooms year-round in the southern states, but in harsher places the foliage turns brown and hangs until bud break. Sometimes a tree sheds its leaves if the air is damp and the winter is very cold. The leaves are lanceolate, dark green and velvety, collected in strong whorls. The flowers are white, with a cream tint and reach only 7 cm in length. The aroma of this magnolia is very rich and pleasant. On average, no more than 15 petals grow on a bud. In its homeland in the subtropics, the flowering of culture is plentiful and lasts from April to July. In the conditions of the middle lane, it blooms reluctantly, from June to August. The fruits are red and smooth seeds that are collected in a loose cluster. The contrast of red seeds against the general creamy green background gives the plant a special attraction. Virginian beauty can be grown in our conditions. To do this, your site must be in a swampy area. These flowering trees have been planted here since time immemorial, but flower growers experience great difficulties with the import and purchase of seedlings. An adult plant is able to withstand short-term frosts down to -30 degrees.
A beautiful hybrid developed in the early 19th century by the French botanist Etienne Soulange. Today, there are more than 50 plant forms in the world, most of which are very popular among professionals. The shrub has obovate leaves and flowers in the form of a glass with a diameter of up to 25 cm. Often the flowers are odorless, but several very fragrant varieties have been bred. The petals are pink, purple and cream, in favorable conditions the flowering is extensive and long. The composition of the soil is almost irrelevant, but rich soil with a high content of humus will be a good help in growing. For the winter, the plant is usually covered and the soil is mulched. It is better to purchase seedlings in places where planting will take place. So the plant quickly adapts and gains resistance to many local diseases. It reaches a height of 10 meters, but for this a tree or shrub must grow in the subtropics. The most famous variety is Alexandria. This drought tolerant shrub has very beautiful creamy purplish flowers. The plant reaches 8 meters in height.
Very popular garden hybrid with pale pink buds. In diameter, the flowers reach 15 cm and are characterized by a large number of petals. Interestingly, as it develops, the plant evolves from a shrub into a small single-stemmed tree and reaches a height of 5-7 meters. This variety blooms in 7-8 years, so it is often grown in greenhouses or for exhibitions. The variety has two separate, ornamental species: "Leonard Messer" and "Merrill".
Dwarf magnolia that grows only one and a half meters. The shrub has dark green, smooth leaves with a glossy surface. This evergreen ornamental plant protects itself from intruders in the wild with small spikes on its leaves. Leaves turn purple in autumn and spring. Holly magnolias fit perfectly into a coniferous garden and can be used as a shade plant. Even if damaged by thrips, aphids and after temperature changes, the plant quickly recovers and is considered frost-resistant.
A magnolia that resembles sakura with its beautiful pink flowers. The shrub has very large buds, a slender trunk and thin branches. The bark is gray, leaf blades are dark green.
The first mention of large-leaved magnolia dates back to 1968. This is a fairly tall tree (up to 23 meters) with a rounded vertical crown that forms in open light. The trunk is straight, with a smooth bark, often branching at the base. The branches have large leaf scars that fit snugly against large shoots. The main decoration of the plant is its huge leaves. They reach a meter in length, blunt at the top, with two so-called "earlobes". Dark green above, and bluish below with fine pubescence. Flowers appear on the uppermost tier of the crown, in the center of a dense whorl. At first they are cream, but over time they become ivory. The fruit is a purple multileaf up to 8 cm in length, ripens in early August. Under natural conditions, it grows in the southern states of the USA, in Florida, Georgia and Louisiana. Thanks to professional flower growers, the plant has acclimatized even in Eastern Europe. However, in mid-latitudes, the tree needs careful care.
The distinctive feature of the lilac magnolia is that it is a sprawling shrub that grows up to only 4 m in length. The leaves are large and decorative, the lily-shaped flowers are white inside and pink outside. This ornamental shrub has become widespread in many countries of Europe and Asia. Holland is considered a leader in their production, local nurseries constantly develop new hybrids and supply seedlings to the whole world. Frost-resistant species, such as Kobus magnolia, are very popular in Eastern Europe and the United States.
Magnolia grandiflora (Magnolia grandiflora)
Demanding and moisture-loving plant native to North America. She has a beautiful crown shape, which must be periodically formed. The leaves are dark green, shiny, grow up to 20 cm long and 12 cm wide. The flowers have a spicy smell, grow up to 30 cm in diameter and are tied one at a time on a branch. At a young age, the species is in no hurry to tie up and grows only 60 cm annually. It does not withstand severe cold below -15 degrees, but it calmly tolerates smog, smoke and is recommended for growing in urban conditions. The fruits are cone-shaped, the leaves contain essential oils and glycosides, and the bark contains alkaloids. Large-flowered magnolia is rightfully considered the queen of the garden and looks great in single plantings in an open area. Experts recommend planting seedlings in mid-autumn. The main decorative forms are early, narrow-leaved, lanceolate and Praverti magnolia with a pyramidal crown.
An ideal species for growing in harsh climates. This deciduous tree can withstand frosts down to -30 degrees. Each year, the tree grows by about 15-20 cm, and in the wild it can reach 30 m in height. The leaves are oval or elliptical, dark green. They grow up to 25 cm in length and are shortly pubescent below. Flowers up to 8 cm, bell-shaped, yellow-green. The shape of the plant is cucumber, the flowers are smaller than most other species, and the leaves are heart-shaped at the base. In the US, flower growers are constantly experimenting with pointed magnolia in order to transfer its frost resistance to more decorative species.
Before planting, it is worth studying the individual characteristics of the plant and carefully prepare the soil. It is the size of the plot that determines your next steps. It should be borne in mind that the tree will grow not only in breadth, but also in depth. Magnolia also loves light very much, and it can be grown far from every region.
What time to plant
Choose a spacious and well-lit area that is well protected from east and north winds. In the shade, the plant can only survive in the subtropics or tropical regions. The soil should be neutral or slightly acidic, without heavy impurities, with a large amount of organic matter. Choose seedlings that already have 1-2 buds, ideally with a closed root system to prevent drying out. If the root system is in a container, then you can plant a plant in open ground in spring, summer and autumn. In autumn, seedlings are almost guaranteed to take root in a new place.
Planting magnolia in spring
Young seedlings are usually planted in spring. The planting hole should be approximately 1 m in diameter, with a pre-prepared substrate of peat, garden soil and sand. For the winter, seedlings must be insulated, otherwise they will not survive their first cold. Peat and compost are suitable for this. Full cover with lutrasil or burlap will protect from wind and temperature extremes. Watch the plant carefully, because winter thaws can cause soil cracking, and a reverse drop in temperature will lead to the death of the seedling. Coniferous bark near the trunk will help retain moisture and protect the plant from pests. Some even believe that when planted in the spring, succulent roots will be able to recover from stress faster.
Site and soil preparation
The planting hole should be approximately twice the size of the seedling's root system. The soil is mixed with compost and other organic matter, after which some river sand is added. A drainage layer is necessarily laid out at the bottom of the pit: eggshell, crushed stone or expanded clay. Then, a little sand is poured out as a gasket, no more than 15 cm thick, and the rest of the hole is filled with a fertile substrate. The seedling is installed in the center of the pit and the voids are tamped with soil. The tree is well watered, it is not necessary to fertilize the soil. When the water is absorbed, mulch the soil with the bark of coniferous trees. In the first 3 years of a plant's life, the near-stem circle should be loosened regularly.
The effectiveness and prospects of crop expansion depend on many factors. There are two main methods of reproduction: seeds and vegetative method. Seeds make it possible to obtain a more flexible material, which, in the process of development, has adapted to the surrounding conditions. Propagation by cuttings or layering leads to the preservation of the genetic characteristics of the mother plant. Each method has its pros and cons, which we will discuss in this article.
Propagation by cuttings
This method is considered the most popular among gardeners. Magnolia seedlings take root well at almost any time of the year. Magnolia cuttings are harvested in the spring. To do this, the branch is cut under the kidney, departing from it by 2 mm. The upper leaves are left intact, and the lower ones are cut off. Too large leaves are shortened by about ⅔. The cutting is then usually treated in a solution that stimulates growth. Two-year-old branches are considered the best planting material. At this age, the seedling has already managed to form, but it is relatively easy to adapt to new conditions. The cuttings are kept in greenhouse conditions until they form a root system. From the moment of cutting to disembarkation, it takes about 2-3 months. You can buy a seedling already prepared so as not to spend too much time on care. The earth is loosened before planting and a suitable substrate is prepared. Watering is done every 3-4 days. Vegetative reproduction under natural conditions also takes place with the help of lower branches, lashes of rhizomes, as well as non-specialized organs. The main advantage of cuttings is reliability and simplicity. If you take a seedling from a plant that grows well in your climate, there is a good chance that the cutting will perform well in the garden and take root quickly.
Propagation by seeds
Magnolia seeds are bought in specialized stores, paying special attention to the quality of planting material. Seeds are first cooked, processed and disinfected, and then sown in open soil from early September to mid-November. Before winter planting seeds in the greenhouse, they must be frozen and hardened. Stratification of seeds takes place at a temperature of + 3-5 degrees. This procedure allows you to prepare the material for the climatic conditions of the middle zone. The substrate must remain moist, but the seeds cannot be poured. In dry soil, they simply cannot withstand frost and die. Freezing of seeds takes place according to a special technology. They need to be cleaned of leaves, husks, sawdust and other impurities, and then planted in moist soil. The seed container is transferred to the refrigerator and kept there for 3 weeks. After that, they are taken out, thawed at room temperature and sown in a container or box with fertile soil.
If everything is done correctly, the first shoots will appear in a month. In this case, the container should be with wide sides (about 30 cm) so that the plant can develop calmly. In early autumn, seedlings reach 20 cm in height and can be transplanted into open ground. The first 3 weeks of sprout life are considered the most important, it is at this time that they are most vulnerable to diseases, drafts and temperature changes. The temperature in the room where the seedlings are stored must be stable. Every day, seedlings need 5-7 hours of daylight, and it does not matter if the light is natural or artificial from lamps. The soil should be moist, not wet. Some growers add complex mineral fertilizers to stimulate growth. Weak and unviable sprouts are pruned so that the plant does not waste precious forces on them. Under natural conditions, magnolia reproduces by seeds, so you can often see small shrubs of the species near a large tree.
Rooting by layering
During rooting by layering, roots begin to form on shoots that have not yet been separated from the mother plant. This method of plant propagation is considered one of the oldest and was successfully used in antiquity. But unlike cuttings or seed propagation, you will need a lot of space in the garden to get a single material. On the other hand, plants grow larger and in a shorter time than with vegetative or seed propagation. To do this, you will need to bend a branch hanging near the ground to the soil and fix it with wooden studs. Then an incision or a wire is made, and the cut is treated with sphagnum moss. The upper part of the layer is brought out, and in place under the wound a recess is made, which is filled with a nutrient substrate. Suitable peat, sand, perlite and garden soil. The recess should be watered regularly so that the soil does not dry out.
Strong roots appear within a year, after which cuttings can be separated from the mother plant, replanted in a separate place or grown in a greenhouse. The shoot is often ringed to encourage an influx of nutrients. The bark is removed entirely and the cut site is treated with nutrients. Magnolia is propagated by layering from early May to mid-July. After 2-3 months, their own roots begin to form on them. Before wintering, the layers are insulated, otherwise they will die during the first frosts. Do not forget about the treatment of the cut and the plant as a whole with fungicides. This is necessary for the prevention of diseases and fungus. Another beauty of rooting by layering is that even if something goes wrong, the main plant will not suffer. Therefore, novice flower growers often practice this particular method.
Magnolia is a very moisture-loving plant, and young seedlings need abundant watering the most. The soil should be watered with settled, filtered or rainwater at room temperature. The soil around the roots is gently loosened with a pitchfork so as not to injure the root system. Around the trunk, experienced growers recommend pouring mulch, otherwise the moisture will quickly evaporate and the frequency of watering will have to be increased.
Asian beauty requires constant top dressing, which begins to be applied from 3 years of age. The first 2 years the seedling will have enough nutrients in the soil. It is better for beginner flower growers not to combine fertilizers, but to choose complex mineral supplements and strictly follow the instructions. More experienced growers can prepare the mixture themselves. To do this, dilute 15 grams of urea, a kilogram of mullein and 20 grams of saltpeter in 1 bucket of water. An adult tree will need about 4 of these buckets to bloom more luxuriantly and increase growth rates. One such procedure is enough for about a month. The plant is easy to overfeed. If the leaves begin to dry out, then top dressing is stopped and for some time limited to simple watering.
Magnolia crown is very rarely pruned and not shaped. Blooming magnolia, catalpa tree and many other exotic species need only sanitary pruning. Cut dry branches and those that have suffered from frost or pests. Wounds are treated with garden pitch or other means. In springtime, even the removal of dried branches cannot be carried out, since the plant secretes abundant juice.
It is recommended to transplant magnolia only in the most extreme cases - in case of soil contamination, natural disasters or a sharp change in soil composition. First, choose the most suitable area on which the plant can grow. A tree or shrub is transplanted only together with an earthen clod, and it should be as large as possible. So the magnolia will more easily endure huge stress and will be able to quickly get used to the new substrate. The root system is transferred in oilcloth or on a stand. The hole is prepared the same as for the primary landing. A drainage layer is laid out at the bottom, and then a plant is placed in the center. Don't use too much force when compacting the soil. The root system is located close to the ground and can be easily damaged. The transplanted plant is watered abundantly, and the space around is mulched. Be sure to treat the trunk and leaves with fungicides and insecticides, and check the roots for fungal disease and other diseases. Even an adult plant that has lived for a long time in the conditions of the middle lane is covered with a film or cloth for the winter. During the autumn transplant, a mound of dry soil is poured near the trunk for the winter.
Magnolia after flowering
Magnolia flowers begin in late spring or early summer. Immediately after flowering, it is necessary to make sanitary pruning. Even a faded plant is highly decorative due to its beautiful dark green leaves. Florists begin to prepare for winter in November. Even if you have a hardy species in your garden, such as a pointed magnolia, it can still freeze. A snowy winter and strong winds have a bad effect on the health of an exotic plant, so carefully wrap the trunk in burlap.
Pests and diseases of magnolia
It was previously believed that magnolia is not affected by diseases known in our area and is extremely resistant to pests. However, scientists have proven that magnolia is susceptible to many diseases, including fungal ones. Chlorosis is considered the main source of problems for magnolia. Because of it, yellow spots appear on the surface of the leaves, while the veins of the plant do not lose their green color. Too much lime in the substrate leads to chlorosis, which negatively affects the root system and can easily lead to the death of magnolia. Acidity is leveled with peat, coniferous soil or special additives. In specialized stores, iron chelate is in great demand and it is sold at fairly reasonable prices.
Nutrient overload leads to drying and curling of the leaves. Magnolia signals too much fertilizer and its general condition, such as the health of the bark. Adjusting fertilizer is quite simple, try 1-2 months just to water a tree or shrub abundantly.
Mealybugs, aphids and thrips also like magnolia leaves and flowers. During the dry season, spider mites and transparent mites may appear on the stems. They feed on the juices of plants and cause the leaves to fall as early as June-August. If measures are not taken in time, the plant will quickly stop blooming. In most cases, this leads to the fact that you can not wait for the next flowering season at all. In addition to direct harm, parasites are carriers of various viral diseases, some of which are incurable. Acaricides and pesticides will help get rid of them. Aktara and Aktellik are considered the most effective, but there are also cheaper analogues. Mulching before the onset of winter helps not only retain moisture, but also protects the roots from rodents. If the plant refuses to bloom, the leaves fall off and the bark looks sick, check the root system. To do this, dig the top layer of soil and, if there is damage, treat the wounds with a 1% solution of Fundazol. Mulching for the winter is also best done after the top layer of the substrate has frozen. In Eastern Europe and Asia, the plant is often affected by fungal diseases. Powdery mildew, scab, sooty fungus and mold appear after too much watering. In this case, the leaves and root system are treated with fungicides, and the affected areas are removed. Usually you have to spray several times and preferably with different preparations so that the fungus does not have time to get used to them and develop protection. A solution of copper sulphate will help to cope with bacterial spotting.
