Rose of Sharon Bush: Pruning & Growing Tips 💡 Gardening |

  • Plant Characteristics
  • Pruning Tips
  • Rose of Sharon Zone, Sun and Soil Requirements, Pests and Diseases
  • Use for Rose of Sharon in Landscape Design
  • Excellent Quality, Growing Tips
  • Plant taxonomy classifies the rose of Sharon, also called "althaea" or "althea", as Hibiscus syriacus , Contrary to its common name, the plant is actually not a rose at all, but a member of the Malvaceae or "mallow" family. It is also not considered native to Syria, despite its species name, most likely on the Asian continent.

    Rose of Sharon is classified by botanists as a deciduous flowering shrub.

    Plant Specifications

    Generally speaking, Rose of Sharon bushes can reach 8-10 feet in height, but they are only about half as wide (they usually have a spread of only 4-6 feet). Their shape and relatively considerable height make them comparable to other tall, tree-like shrubs. However, some cultivars remain shorter (e.g. Hibiscus syriacus 'Minerva' only reaches 5-8 feet). The flowers on these bushes can be white, red, lavender, or light blue; some of them have double flowers. Most of them have small, deeply lobed, light green leaves (this trait may vary by variety).

    Pruning tips

    Although a naturally multi-stemmed shrub, this plant can be trained by pruning to have only one main chest; hence some people call it the Rose of Sharon "Tree". Cut back in late winter or early spring, as this is one of the shrubs that bloom this season. It is easiest to give the Rose of Sharon the desired shape by pruning it accordingly during the first two seasons.

    He can also be trained for espalier.

    Rose of Sharon Zone, Sun and Soil Requirements, Pests and Diseases

    The climate is most favorable for growing Rose of Sharon in USDA plant weathering zones 5-9.

    Rose of Sharon prefers full sun and well-drained soil. Older shrubs can fall victim to fungal damage if you grow them in areas without full sun.

    This is due to the fact that excess moisture is retained in shaded areas, and it is in humid conditions that the fungus thrives. This plant profits from growing in rich soil, so fertilizer is recommended (although not required for established shrubs). If you want to stay organic, carefully compost the compost in the soil around the root zone and pour it into the soil.

    The main pest problem for this shrub is Japanese beetle infestation. Luckily, Japanese beetles are somewhat easier to control than many other insect pests because they are large enough to spot right away - before they do too much damage to your plants. The easiest and safest way to kill them is to pick and/or hand shake them by dropping them into a container filled with soapy water. The insect breathes through its skin, so the soap coating over its body is effectively suffocated.

    Use for Rose of Sharon in landscaping

    Three popular uses for this shrub:

    1. Specimen
    2. Hedge plant
    3. Base shrub

    It's attractive and abundant flowers make this plant fully capable of holding. The ability to form a rose of Sharon also makes the shrub a prime candidate for hedges. But since this shrub is deciduous, it only makes an effective thirst defense in summer (choose one of the evergreen shrubs to get privacy all year round).

    However, it can be used to provide privacy around pools in areas with cold winters, as you will most likely only swim there during the summer. However, be aware that its flowers may attract bees, which are usually unwanted visitors in basin areas. Because the shrub responds well to annual pruning, it is quite useful for foundation planting where it is important to be able to control the growth of the plant (to avoid crushing it in your home).

    Excellent quality, growing tips

    The Rose of Sharon blooms profusely and its attractive flowers are its main selling point. Like other types of hibiscus, its flowers have a striking stamen. Another feature that gives artisanal value is the relatively late flowering period (in the northeastern states, it blooms in August).

    Rose of Sharon is thus able to offer color when many flowering shrubs have long ceased to bloom. It is imperative that gardeners be able to grow these late summer flowering shrubs if they intend to manage the flowering sequence in their landscapes.

    A heat lover, this shrub is also prized by growers in the southeastern United States who crave plants that can withstand hot summers. The plant is fairly drought tolerant. In fact, if your Rose of Sharon has yellow leaves, it could be due to over and not lack of water.

    Don't dismiss the Rose of Sharon thinking it's dead just because it didn't bloom before summer. This plant not only blooms, but also late, so be patient. When Althea flower buds don't open, that's another matter.

    And these are not the only problems associated with the growth of Hibiscus syriacus . Its seeds drop and sprout where you don't want, and therefore the need to remove young plants by hand, is hardly conducive to low-income landscaping. However, for those seeking help with this matter, I offer an alternative to pulling out unwanted volunteer plants in my article on getting rid of altea seedlings.

    Rose of Sharon - not the only type Hibiscus which thrives outside of tropical and subtropical regions, although when you hear the genus you're talking about it might very well immediately think of the tender types that show up in greenhouses. Another hardy hibiscus Hibiscus moscheutos , known for its giant flowers.

    Due to the variety of shapes and colors of flowers, habit of bushes, unsurpassed aroma and remontant flowering, roses confidently take pride of place in our gardens and parks. I like roses not only for their beauty, but also because, despite the capriciousness of this culture, they allow solving complex tasks in landscape design that other ornamental shrubs cannot do. Now in the world flora there are more than 150 species and several thousand varieties of roses, which are combined into eight groups - park, tea-hybrid, floribunda and polyanthus, bush scrubs, miniature, ground cover, climbing and Canadian.

    ✔ Irreplaceable roses in small gardens, summer cottages and household plots, where they usually occupy a central place in compositions. When choosing varieties of roses for small gardens, you should be aware of the limitation of space in the plots. However, the modern variety of varieties allows you to choose roses even for a miniature garden. A skillfully selected assortment of roses will ensure that they perform not only the main aesthetic function, but also protective, thermoregulatory, delimiting, and the like. Roses can be used in almost all elements of green building - to create hedges and vertical gardening, in solitary plantings and groups, in the form of a monogarden - a rose garden. Of course, roses are ideal for all types of floral arrangements - borders, flower beds, parterres, mixborders and rockeries. Recently, mobile flower beds made of roses in containers have become popular.

    ✔ By arranging a rose hedge around the perimeter of the plot, we will isolate ourselves from neighbors, close the site from “curious eyes”, intruders, dust and street noise. In addition, using wild types of dog rose - dog, wrinkled, gray, white, Dahurian, cinnamon in the fall we get healing high-vitamin fruits. Wild rose hips for hedges are planted in one row at a distance of 70–80 cm. They are planted in hedges and varieties of park roses in two rows with a distance between rows of 80–100 cm. One variety of roses is planted in such hedges, although 2 can be combined –3 cultivars, taking into account the height, habit and flower color of the cultivars. Promising in hedges varieties of park roses "Westerland", "Rosarium Utherzein", "William Morris", "Spirid off Freedom".

    ✔ Indispensable in small gardens and climbing roses, which are divided into two groups of small-flowered - ramblers and large-flowered - climber. The former are able to braid the supports well, while the latter need a mesh or lattice. Fences, walls of buildings can serve as supports for climbing roses in a small garden. With the help of climbing roses, you can equip trellises, obelisks, bersos, arches, pergolas, which will create a romantic intimate atmosphere in the remote corners of your garden. Blooming fountains, obelisks and columns with roses can be arranged using a frame on a lawn, in a mixborder or rose garden. The most popular climber varieties are Golden Showers, Indigoletta, Elf, Casino, Laguna, Golden Autumn, Natheglut, Schwanense, Crown, Polka; Rambler - Blue Boss, Blue Moon, Carmen, Mite Tower, Amadeus, Caesar. When arranging vertical gardening, it should be remembered that supports, nets, gratings must correspond to the architectural style of the building and the entire garden. Ground cover roses with flexible drooping shoots can be used to decorate hanging planters and baskets.

    ✔ In solitary plantings, roses are planted against the backdrop of a lawn, paved areas, at the turn of stairs, slopes, etc. For solitary plantations, you can use standard, climbing, hybrid tea roses, floribunda, scrubs and even ground cover roses. The choice of a group of roses depends on the style and size of the garden. If the size of the garden allows, then you can create a group of tall hybrid tea roses or plant 3-5 standard roses on the lawn. Nurseries offer standard varieties of roses 0.4–0.6, -0.9or 1.4 m tall. The optimal stem height is 0.9 m.

    ✔ Mobile rose beds in containers are very popular. Roses in tubs decorate sidewalks, terraces, balconies, patios. From the group of miniature for container culture, the varieties Lavender Ice, Arow Folies, Red Cascaded, Gold Baby, Red Macarena are suitable.

    ✔ The most common in landscape design are flower beds with roses. If the flowerbed is planted mainly with roses, then it is more correct to call it a rose garden. In large gardens and parks, rose gardens are complex compositions of flower beds, borders and borders, where each compositional element is represented by only one variety of roses.

    ✔ Roses are also used in the stalls for flower and decorative decoration of parade areas in both regular and landscape gardens. Usually parterre includes borders, ridges, flower beds, arabesques, sculpture, ponds and fountains.

    ✔ One of the ancient elements of floral design is the border, which performs the function of delimitation and shading in landscape design. Border - a monotonous flower garden, where one variety of roses of the same color is usually used. For low borders 20–40 cm high, patio and miniature roses are used, for medium (50–60 cm) - low varieties of spray floribunda and ground cover roses, for high (80–100 cm) - high varieties of floribunda and low scrubs.

    ⌂ Rose border

    ✔ In small gardens, small varieties of roses with a compact crown are planted in flowerbeds along paths in several rows. In one discount, you can plant one or two or three varieties of roses of different sizes and colors. Rabatki can be unilateral or bilateral review. In accordance with this, an assortment of roses is selected for discounts, taking into account the height and color of the plants. It is better to use bush and ground cover forms of floribunda and scrubs of appropriate height for rabatok.

    ⌂ Mixed flower beds

    For a long time it was believed that the highest decorativeness of roses is achieved in a monogarden. But new trends in green building have also reached roses, which are increasingly planted in mixed flower beds - mixborders and rocky gardens. It should only be remembered that partners of roses must have the same requirements for soil, moisture and lighting. It is also necessary to take into account the timing of flowering and the height of roses and their satellites. Do not use plants with a short decorative period and plants with large bright flowers in joint plantings. It is optimal to choose plants with contrasting inflorescence forms - paniculate, spike-shaped. Partners of roses in miskborders are aconite, initial letters, anafalis, yaskolka, chistets, brunner, soft cuff, Wittrock violet, narrow-leaved lavender, caustic ranunculus f. terry, various types of gypsophila, varieties of veronica, sage, astilbe, clematis, bluebells, geraniums, blue-leaved varieties of hosts and ornamental cereals - blue sisleria, evergreen fescue, varietal elimus. Early spring bulbous varieties of saffron, daffodils, hazel grouse, tulips, iridodictiums; flower beds in the spring, when roses do not bloom yet.

    ✔ The most demanding hybrid tea roses should be given a place in a rose garden, and roses of all other groups are quite suitable for use in mixborders, and they are selected depending on the planting place in a mixed flower garden. In the background of the mixborder, tall roses are planted: specific, climbing, high scrubs; on the middle - undersized scrubs and high floribundas; on the front - undersized floribunda and ground cover roses. The number of rose bushes in a mixborder depends primarily on its size, but there should not be many of them, they can be placed on different plans of the flower garden, but should not prevail over other types of plants, otherwise it will not turn out to be a mixborder, but a rose garden with plants of other species . But no matter how many rose plants, no matter what varieties and garden groups are used, roses should be accent plants in such mixborders - the center around which the whole composition is built. So, when designing a mixborder with roses, rose bushes are first placed on the plan, and only then, according to its size and color, partners are selected for the selected variety in terms of color, habit, shape of inflorescences and leaves.

    ✔ Ground cover and miniature roses are planted in rockeries and rock gardens to stabilize slopes.

    ✔ As for the use of roses in the landscaping of preschool and school educational institutions, according to the rules of landscaping, thorny plants cannot be used in them. But here, too, the selection of roses does not stand still. Today, among the tea-hybrid roses and scrub, varieties without thorns have been bred, which can be successfully used for landscaping schools and kindergartens.

    ✔ In conditions of unstable winters, a new variety group deserves attention - Canadian roses, which can withstand frosts down to -30–35 ° C. These are tall scrubs, climbing and spray roses, bred in Canada and the USA. The most popular variety series is "Easy Elegansce".

    ✔ Set up a rose garden in a well-lit and wind-sheltered area. The best soils for roses are well-drained loams with an acidity of pH 5.5-6.5. Spring planting of roses is recommended when the soil warms up to + 10 ° C. For a rooted rose, the fertile soil layer must be at least 50 cm thick, and for grafted roses - up to 70 cm. When planting roses, they are guided by the rule according to which the depth of the pit should be greater by 10–15 cm of root length and is usually 45–50 cm, and a width of 50 cm. Its content is humus or compost, rotted manure and the soil itself. Fertilizers should not come into contact with the roots of the plant, so you must first sprinkle them with a layer of soil. When planting roses with a closed root system, it is necessary to save the substrate of the container, which will help the roses quickly adapt to new environmental conditions. Polyanthus, hybrid tea roses and floribunda are planted at a distance of 30-60 cm, ground cover and miniature roses - at a distance of 30-40 cm, and the optimal distance between climbing rose bushes is one meter.
