Life Expectancy of Ornamental Cherry Trees | Home Guides

By SF Gate Contributor Updated May 13, 2021

You grow ornamental cherry trees (Prunus spp.) for their shape and scented flowers, rather than as a source of fruit. Like their fruiting cousins, ornamental cherry trees are fast growers in U. S. Department of Agriculture plant hardiness zones 4 through 9, with a shorter average life expectancy than other landscape trees. When growing an ornamental cherry cultivar, including the popular 'Kwanzan' flowering cherry, its normal 15 to 20 year lifespan is often shortened due to disease, pest infestation or poor conditions. They require careful attention to maintain good health.

Growth Rate and Size

Most ornamental cherry trees are considered fast-growing plants, with a height increase of more than 25 inches per year. Some larger varieties have a slightly slower growth rate and tend to live longer. As Clemson Cooperative Extension points out, 'Higan' cherries (Prunus subhirtella var. 'Autumnalis') reach heights of up to 30 feet in about 25 years, while the slower-growing Japanese 'Yoshino' cherry trees (Prunus x yedoensis) can get up to 50 feet high but take much longer to reach full height. Some types of ornamental cherry tree are remain quite small, such as the 'Nanking' cherry (Prunus tomentosa), which reaches only about 10 feet tall.

Lifespan of an Ornamental Cherry

On average, ornamental cherry trees live between 15 and 20 years, but some varieties can survive longer with the correct care. For example, 'Yoshino' cherries normally live only into their second decade, but some specimens in Washington, D.C., have survived since their donation in 1912 by the Japanese government. 'Higan' cherry trees are among the most stress-, heat- and cold-tolerant varieties and tend to survive well past their 20th year.

The oldest known flowering cherry trees are in Japan. According to NPR, the Takizakura or "waterfall cherry tree," is more than 1,000 years old and still blooming despite the disastrous 2011 earthquake and resulting tsunami and radiation from the damaged Daiichi nuclear power plant. Older still is the Yamataka Jindai Zakura, an 1,800- to 2,000-year-old weeping double blossom cherry tree of the Edo-Higan type that blooms around the 20th of March, or the spring equinox.

'Kwanzan' Cherry Tree Lifespan

The environment of a 'Kwanzan' or any other ornamental cultivar can have a significant effect on its lifespan. Ideally, these plants should be planted in moist soil with extremely good drainage and oxygenation. Cherry trees cannot tolerate salty soils, so use caution when planting near the coast or commercial farming operations where fertilizer salts may affect the soil.

The flowering cherries do best when planted in full sun in temperate climates. Where summers are hotter, USDA zone 8 and above, you may need to plant your ornamental cherry tree in partial shade or where it receives dappled shade in the afternoon to prevent heat damage.

To increase an ornamental or 'Kwanzan' cherry tree lifespan, take time to prune every winter when the tree is dormant. Cherry trees need regular pruning to remove dead or diseased wood. Be sure to put on safety goggles and gloves and sterilize your pruning tools in rubbing alcohol or Lysol.

Pest and Disease Control

Many ornamental cherry species are highly susceptible to pests and diseases. They can suffer heavily from mites, scale insects, leaf rollers, boring insects and aphids. Fungal diseases are also common, especially in areas with high humidity.

You can increase the expected lifespan of your ornamental cherry tree by planting it in a location with good air circulation and well-drained soil, which helps prevent wet roots. Handpick or knock pests off with a blast of water. In addition, This Old House recommends removing and destroying any diseased or infested wood as soon as you notice it to keep the problem from spreading.

    This variety has large, elliptical leaves. In summer, they are green, and in autumn they turn into a yellow-purple tone.

    Kiku-Schidare Cherry blossoms in March. The inflorescences are very dense. They are located along the entire length of the branch. Under the weight of the inflorescences, the shoots droop down.

    The fruits are small in size, quite pleasant in taste, with a slight sourness. Since the plant is self-fertile, it can be grown as a single specimen.

    Kiku-Schidare should be grown in moderately moist soil rich in nutrients.

    Shiro Fugen


    Sakura variety "Shiro-fugen"

    The variety is beautiful with its white inflorescences with a pink tinge. Flowering is quite long, plentiful. Yield is high.

    Planting Japanese Cherry Sakura in open ground


    Japanese Cherry Sakura takes root well in a new place, quickly begins to grow. However, in order for the tree to be comfortable on the site, so that it blooms profusely and gives a rich harvest, certain rules will have to be followed.

    Site selection


    The best place for Cherry Sakura is a gentle slope or hill. It must be bright and sunny. Experts recommend choosing a site located in the eastern or southwestern or northwestern part of the garden.

    If ​​Sakura is dropped off in a gentle valley, she may freeze. In addition, the tree must be protected from strong gusts of wind, drafts, and therefore it is better to plant it near a fence or trees.

    When planting in groups, the distance between trees should be 1.5-2 meters.

    Planting time


    Japanese Cherry Sakura is best planted in early spring, especially if it is warm and sunny. It is important that the snow is completely gone by this time, and the topsoil is thawed. You can also plant in the fall - in October.

    Choosing a seedling


    In order to grow a healthy, beautifully flowering and well-bearing tree, it is important not to make a mistake in choosing a seedling. It is better to acquire one-year-olds with a developed root system. The height of the seedling should not exceed 70 cm.

    Soil composition


    Cherry Sakura has minimum requirements for soil composition. The reaction can be any with a slight deviation from neutral. It will be nice if the seedling is planted on fertile air and water permeable soil.

    Method of planting seedlings


    Having chosen a favorable place for growing Cherry Sakura, it is necessary to prepare planting pits for seedlings. You need to dig them out in advance. A mixture consisting of humus and a fertile topsoil is added to the planting pit. Before planting the seedling directly, a 3% solution of superphosphate and potassium phosphate is additionally added to the planting pit. After planting, the tree is watered abundantly, the soil is mulched.

    How to take care of Japanese Cherry Sakura


    With proper and serious care of Sakura Cherry, you can achieve abundant flowering, a good harvest for a long time.

    Watering


    Water the tree regularly, but in moderation. The soil should be constantly slightly moist. During the period of active growth, in the phase of bud and ovary formation, the plant will need additional watering. To prevent moisture from evaporating quickly, the trunk circle should be mulched with a 5-cm layer of fir needles or cut straws.

    Top dressing


    Sakura especially needs nitrogen, potassium and phosphorus. With their lack, the tree begins to shed flowers and leaves. To prevent this, in the spring it is necessary to feed the tree with organic matter - humus or compost (about 8 kg per 1 sq. meter). Mineral fertilizers should not be neglected, for example, add superphosphate at the rate of 18 g per 1 sq. meter.

    Pruning


    In order for a tree to look neat and beautiful, it is necessary to trim it. The best time for this procedure is early spring, until the plant begins the process of sap flow. As a rule, pruning is carried out in late March - early April.

    It is necessary to remove shoots that have been frozen in winter, have been damaged by a thick layer of snow or from gusts of wind. Dry wood should also be removed. The places of cuts are processed with garden pitch, and if it is not at hand, then you can use brilliant green.

    Preparing for winter


    In late autumn, before the onset of frost, it is necessary to wrap the grafting site and stem with non-woven covering material. Large branches and trunk are covered with agrofibre.

    Preventive treatment against diseases and pests


    In order to prevent the defeat of Japanese Cherry Sakura by various fungal diseases, the appearance of pests, it is necessary to take timely preventive measures. After flowering is completed, the crown of the tree should be treated with Nitrofen. The recommended dose is 200 g of the drug per 10 liters of water.

    To prevent the appearance of aphids on the tree, it is necessary to treat Sakura with a nettle solution. It is prepared as follows: 1 kg of fresh nettle or 0.5 kg of dried nettle is poured into 10 liters of cool water, left for a day to infuse.

    Propagation


    Japanese Cherry Sakura can be propagated in two ways - seeds (stones) and cuttings.

    Propagation by seed (stone)


    The container is filled with a substrate consisting of river sand, sawdust and ash. The day before planting, the bones are soaked, and then placed in the substrate to a depth of 1 cm. The container is covered with glass or film, and then placed in the refrigerator for 2 months. During this time, the seeds will undergo stratification. From time to time, the degree of moisture content of the soil mixture should be checked, if necessary, moistened.

    After 2 months, the container is transferred to a warm room, installed in a bright place. Now it remains to wait for the seeds to sprout. When they appear, the shelter is removed from the container, then grown like any houseplant.

    Cuttings


    This operation is best done in summer. At the shoot, the extreme part is cut off (about 12 cm). It is necessary to ensure that there are three or more points of growth on the handle. The resulting cuttings are placed in a soil mixture prepared from river sand and peat. The optimum temperature for rooting is +18°C. When the cuttings have thin roots, they are transplanted into separate cups and cleaned in a cool room with a temperature of + 8 ° C, where they will stay all winter. In spring, the young plant is transplanted into a new pot filled with nutrient soil. A tree can be planted in open ground only after 3-4 years.

    Difference of Japanese cherries and other varieties

    Trees belong to the pink family and reaches the pink natural environment 20 meters high. Modern selection has about 400 varietal variants.

    Breeding of horticultural varieties is based on grafting and crossing cultivated species with serrated wild cherries.

    Sakura is characterized by spreading round crown . Its bark is brownish-red in color and covered with a network of small cracks.

    Cherry-sakura belongs to ornamental plants, its fruits are not suitable for eating

    Oval leaf blades with notches around the circumference change color in autumn in the range from dark crimson to brown. The fruits are not suitable for eating , therefore cherry-sakura is classified as an ornamental plant.

    East Asian cherries have won planetary fame by colorful flowering. The petals of the plant have shades of white and pink tonality. There are species with yellow, red and crimson brushes.

    During the period of their dissolution, Japan cancels working days and declares Hanami as a national holiday.

    Meaning of the plant for the Hanami festival

    According to one version of , cherry blossom petals were dyed red with the blood of family members of one of the village elders.

    After he showed the ruler the scars on the backs of his children due to the cruel treatment of the prince's servants, the latter flogged them to death on the top of the mountain where the cherry blossoms grew.

    Falling petals turned pink from blood stains. Now they symbolize the fragility of children's lives in the modern world .

    The celebration of Hanami is symbolically carried out in a family atmosphere. The duration of the process depends on the flowering period of the legendary cherry.

    When the sakura blossoms, Japanese working days are canceled and Hanami is declared a national holiday

    Each tree blooms for several days : sooner or later, depending on the species. As a result, a chain is formed - flowering plants pass the baton to blooming ones.

    Japanese media notify residents in advance of the estimated time of cherry blossoms and its duration: many prefer to travel around the country to catch the grandiose spectacle repeatedly.

    Traditionally Hanami falls at the end of March or beginning of April .

    Main varieties

    Kiku shidare

    The most suitable garden cherry variety for steppe and forest-steppe zones with temperate continental climatic conditions. Healthy trees grow to a height of 4 m, with an annual growth of about 30 cm.

    The crown of Kiku shidare plants is spreading and prone to thickening. The leaf blades have an elliptical shape with small frequent notches along the cut and a relatively large size (7-9 cm).

    The decorative feature of kiku shidare lies in an early prolonged flowering period (the end of March - the first ten days of April). Brushes of large-diameter (5-7 cm) densely double pink flowers are numerous and abundantly cover the branches.

    Self-fertile variety . A singly planted tree with qualified care intensively blooms and bears fruit.

    Prefers full sun on sandy clay, alkaline or neutral soils. The abundance of flowering depends on the regularity and timeliness of fertilizing with superphosphates.

    Kanzan

    This small-serrated tree-like variety of garden sakura is lower than its ornamental counterparts (up to 10 m in height for an adult tree). The shape of the crown is obversely conical. Because of this, kanzan is recognized as an exotic and creative decoration of suburban areas.

    The speed of growth of trees of the variety is medium. The elongated oval-shaped foliage becomes fiery yellow with the advent of autumn.

    Sakura kanzan blooms with massive fragrant pink flowers , which are grouped into hanging elongated inflorescences of 3-6 pieces. The duration of flowering is average.

    The plant is photophilous and prefers neutral or strongly alkaline soils.

    Sakura Kanzan is photophilous, blooms with massive fragrant pink flowers

    Planting and cultivation

    For planting ornamental sakura, it is necessary to choose a lighted and ventilated area without moisture stagnation during periods of floods and rains. Hills and elevations are the best choice.

    When choosing a landing site, it is necessary to strike a balance between light transmission (sakura does not like shadows) and the absence of strong winds. The wall option may be ideal.

    It is recommended to opt for grafted seedlings , which are traditionally purchased in the fall and aged until the spring thaw in humid spaces at room temperature. Before planting, the plants should have a height of about 1.5 meters, a mature trunk and a well-formed root network.

    Planting is preferably done in late autumn or early spring , before the buds swell, with a stable warm temperature regime. Simultaneous planting of several seedlings provides a greater degree of profusion of flowering and fruit formation in the future.

    Plants should be planted at a distance of 1.5-2 m from each other and between rows of 2.5-3 m. It is advisable to place in them a mixture of the upper fertile layers of the earth and humus.

    Immediately before planting, it is necessary to fertilize the soil with 15-18 liters of potassium sulfate solution with the addition of superphosphates. Do not cover the root collar with earth .

    At the end of planting, the near-stem zone is watered and carefully mulched with humus or a thin layer of peat 4-5 cm. It is impossible to allow damage to the root system and promptly remove weeds . In this case, the sakura will strengthen faster and overwinter without damage.

    Care instructions

    Successful growth of sakura is possible with proper care of and the creation of optimal conditions for development. Systematic drainage and regular feeding contribute to the growth of a healthy tree.

    The condition of cherries is largely influenced by the content of nitrogen and potassium in the soil. Their lack is fraught with manifestations of acute reactions of sakura: poor flowering and premature shedding of foliage.

    Soil depletion is eliminated by introducing humus and compost (6-8 kg) under each root. Chemical top dressing is carried out with a solution of the necessary elements at the rate of 15-18 g for one square meter of the near-trunk zone.

    A few heavy waterings of sakura are allowed during the active growth stage. The rest of the time it is enough to maintain the natural balance of soil moisture. Excessive moisture results in low bud formation, poor flowering, and reduced petals.

    Young sakura needs additional feeding, infrequent watering, pruning and shelter for the winter

    Before the start of sap flow in early spring dry and damaged branches are cut, the crown is thinned .

    Mature plants are frost-resistant , and young trees successfully winter in a sheltered form. Before the start of the cold season, graft sites, stems and bases of large branches are wrapped with agrofiber or improvised materials that do not create a greenhouse effect.

    During the vegetative season , the sakura is sprayed with chemical preparations : primary - before flowering, secondary - after a month after the berries are set.

    Cutting

    Removal of affected and dried branches , sprouts that prevent comfortable light absorption and sufficient air exchange, is carried out in early spring, before the start of sap flow.

    Fragments with traces of activity of harmful organisms are subject to cutting and burning.

    Cut areas should be treated with garden pitch . It is important to ensure that gum does not form at the site of the sections. The appearance of sticky growths is excluded in the case of competent drainage and watering.

    Diseases and pests

    If ​​the sakura is affected by harmful organisms, the intensity of flowering decreases, the petals wrinkle, and the tree develops behind the norm. There may be facts of exfoliation of the bark and the formation of growths.

    A common disease of sakura, as well as other cherry trees, is fungal infection, which leads to drying of foliage, blackening and mummification of berries .

    A spray of sulfur-charcoal powder can help the plant in this unpleasant situation. It should cover the affected segments and prevent further spread of fungal aggression.

    A common ailment of sakura is a fungus that leads to drying of foliage, blackening and mummification of berries. Healthy and infected leaves and branches must be taken outside the site and burned.

    This precaution prevents the spread of fungal diseases to neighboring crops.

    The effect of combating pathogenic organic matter is enhanced by the use of insecticides. Restrictions on the use of chemicals are imposed on the period of flowering and fruit set. In case of urgent need, this rule can be neglected.

    Growing one of the most spectacularly flowering plants on the planet on a personal plot is a feasible task and does not require excessive physical, material and emotional expenses.
