How to propagate Sorbaria sorbifolia? Detailed methods for sowing, cuttings, division and layering
Sorbaria sorbifolia is a fairly common flowering plant in people's lives. This flower naturally has a fresh quality, so it is also loved by many people, and many people in China grow it. As more people grow it, questions about its propagation have also drawn people's attention, so how do you propagate Sorbaria sorbifolia? What are the propagation methods of Sorbaria sorbifolia? Below, the editor takes everyone to learn about it.
I. How to propagate Sorbaria sorbifolia
II. Propagation methods of Sorbaria sorbifolia
1. Sowing propagation
Among the propagation methods of Sorbaria sorbifolia, sowing propagation is a relatively rarely used method. Although it can be sown, because the seeds are too small, not many people use it. When sowing Sorbaria sorbifolia, we need to mix the seeds with fine sand and scatter them. After scattering, cover them with 1-2cm of soil and then water. When watering, be careful to water thoroughly at one time, and after about 15 days they can germinate.
2. Cutting propagation
Among the propagation methods of Sorbaria sorbifolia, cutting propagation is mainly used when mass-propagating Sorbaria sorbifolia. Generally, cuttings taken in March or October each year root relatively quickly. Before cutting, we should choose robust growing branches, so the survival rate will be greatly improved. When cutting, we should insert the branches two-thirds into the soil, then water thoroughly and leave them for about 1 month, after which they can root.
3. Division propagation
Division propagation is a relatively commonly used propagation method for Sorbaria sorbifolia, generally best carried out in March-April. When carrying out this propagation method for Sorbaria sorbifolia, we should first carefully dig the mother plant out of the soil, then separate the tillers from the mother plant in the middle. The separated tiller seedlings must have complete roots, and then they can be planted. After planting is completed, they need to be kept in a shaded place for about a week, and then moved outdoors to receive light.
4. Layering propagation
For layering propagation of Sorbaria sorbifolia, it is also best around March-April. When carrying out this propagation method for Sorbaria sorbifolia, we need to bend the branches on the outer edge of the mother plant down into the soil to grow. After new roots grow, they can be separated from the mother plant.
III. Follow-up management
After Sorbaria sorbifolia has been successfully propagated, we can carry out follow-up care. There are also many points to note when caring for Sorbaria sorbifolia. For specific details, everyone can refer to the article on how to grow Sorbaria sorbifolia, which has detailed teaching. The editor will not repeat it here.

Cultivation methods and precautions for Sorbaria sorbifolia Introduction to Sorbaria sorbifolia
Sorbaria sorbifolia is native to northern Asia, and is distributed in Hebei, Gansu, Shandong, Shanxi, Inner Mongolia, Jiangsu and other places in China. It is a shrub-type, deciduous broadleaf shrub plant. It likes sunlight and also has strong shade tolerance, and is cold-resistant, moisture-resistant and drought-resistant. It is not strict about soil requirements and can grow normally in ordinary soil, while growing more vigorously in moist and fertile soil. It grows quickly, has strong sprouting ability, and tolerates pruning.
Spiraea thunbergii is a plant in the Rosaceae family, Sorbaria genus. Because its flowers are dense and all white when blooming, it got this name. Also because its leaf shape resembles willow leaves and its flowers are white as snow, it is also called "Snow Willow." Sorbaria sorbifolia is mostly planted as a single plant in gardens and courtyards. Generally it does not need fertilizing, but it must be watered frequently, especially in dry spring and summer when the soil must be kept moist.
Before winter, water sufficiently with winter water. In high-cold regions, it should be protected for overwintering. Other management is relatively extensive. Sorbaria sorbifolia has full plant clumps and elegant branches and leaves. Its value lies in producing elegant white flowers in midsummer when flowers are scarce, and the flowering period is very long. In particular, it has a killing or inhibiting effect on many harmful bacteria, and is suitable for planting in all kinds of garden green spaces. Especially because it has shade tolerance, it is therefore a flowering shrub species for greening the shady north side of high-rise buildings and various structures in northern cities.
Morphological characteristics of Sorbaria sorbifolia
Sorbaria sorbifolia is a shrub, up to 2 m tall, with spreading branches; branchlets cylindrical, slightly flexuous, hairless or slightly short-pubescent, green when young, dark reddish-brown or dark yellowish-brown when old; winter buds ovate, apex rounded and blunt, hairless or slightly pubescent at the tip, purplish-brown, with several alternate exposed scales.
Pinnate compound leaves, leaflets 11-17, together with petiole 13-23 cm long, 10-13 cm wide, leaf rachis slightly short-pubescent; leaflets opposite, 2-2.5 cm apart, lanceolate to ovate-lanceolate, 5-7 cm long, 1.8-2.5 cm wide, apex acuminate, rarely caudate, base nearly rounded or broadly cuneate, rarely oblique, margin sharply doubly serrate, both surfaces hairless or nearly hairless, pinnate reticulate veins, with 12-16 pairs of lateral veins, obvious below; leaflets sessile or nearly sessile; stipules herbaceous, ovate-lanceolate to triangular-lanceolate, apex acuminate to acute, margin irregularly serrate or entire, 8-13 mm long, 5-8 mm wide, slightly short-pubescent outside.
Terminal large dense panicle, branches nearly upright, 10-20 cm long, 5-12 cm in diameter, peduncle and pedicels stellate-hairy or short-pubescent, gradually shedding in fruit stage, nearly hairless; bracts ovate-lanceolate to linear-lanceolate, 5-10 mm long, 3-5 mm wide, apex long acuminate, entire or with shallow teeth, both surfaces slightly pubescent, gradually shedding in fruit stage; pedicels 5-8 mm long; flowers 10-12 mm in diameter; calyx tube campanulate, outside slightly short-pubescent at base; sepals triangular-ovate, apex obtuse or acute, sepals about as long as calyx tube; petals oblong or obovate, 5-7 mm long, 3-5 mm wide, white; stamens 40-50, about 1.5-2 times as long as petals, borne on the edge of the disk; carpels 5, hairless or slightly pubescent.
Follicles oblong, with terminal curved style, about 3 mm long, fruiting pedicel upright; sepals persistent, reflexed, rarely spreading. Flowering period July-August, fruiting period September.
Ecological habits of Sorbaria sorbifolia
Sorbaria sorbifolia is cold-resistant, semi-shade tolerant, and pruning tolerant. It grows better in well-drained sandy loam. It grows fast, sprouts easily, and is a good summer flowering ornamental plant.
Most plants in the Rosaceae family are sun-loving, and Spiraea thunbergii is no exception. It likes sun and tolerates a certain moist and wet environment, but should not be waterlogged for a long time. It is not strict about soil requirements and tolerates a certain degree of salinity and alkalinity, and is suitable for growing in the Shanghai area.
Cultivation techniques for Sorbaria sorbifolia
Sorbaria sorbifolia has strong adaptability and does not demand much fertilizer. Aside from newly planted plants needing a small amount of base fertilizer, afterward no further fertilizer is needed, but watering is required. Generally, during the period from leaf bud sprouting to flowering, water thoroughly 2-3 times; from the beginning of autumn to before frost, water 2-3 times, including 1 anti-freezing watering. In summer, water according to drought conditions; when there is a lot of rain, no watering is needed. After the flowers fade, the inflorescence turns yellow and withered, affecting appearance, so the remaining inflorescences should be cut off to keep the plant clean and neat, and to avoid the remaining inflorescences competing with the plant for nutrients and water. After autumn or in early spring, diseased and pest-damaged branches and old weak branches should also be cut off. Annual branches can be heavily pruned to promote branch renewal and lush flowers and leaves.
① It is not strict about soil requirements, but grows better and blooms more profusely when cultivated in deep, fertile sandy loam.
② It does not demand much fertilizer. When first cultivated, sufficient base fertilizer should be applied to meet its growth requirements, and generally no additional topdressing is needed. Afterward, combined with winter management, applying base fertilizer once every 1-2 years is sufficient.
③ In dry spring, water in time. In dry summer and autumn, water thoroughly to keep the soil from drying out; before winter, water once with anti-freezing water.
④ After flowering, promptly prune off remaining flower branches, diseased and pest-damaged branches, and old weak branches, to keep the plant shape neat, avoid nutrient consumption, and promote robust growth and lush flowers and leaves.
Propagation methods of Sorbaria sorbifolia
Propagation of Sorbaria sorbifolia is mainly by division, and it can also be sown. However, because the seeds are small, the sowing method is mostly not used. Division propagation is generally carried out before spring sprouting or after leaf fall in autumn. Dig out the clustered sprouting seedlings at the base of the plant with roots, take 3-5 plants as a clump, and plant them separately.
When planting, apply 2 shovelfuls of compost in the hole as base fertilizer, and water thoroughly after planting. Afterward, water about once a week until established. Plant clumps over 5 years old can grow into a very large crown width. In early spring before sprouting, the soil around the old clump can be dug open, and then the root tiller seedlings around it can be cut away from the mother body one by one and dug out, moved to a nursery for cultivation, and after 1 year they can become saleable seedlings. When propagating seedlings in large quantities, the sowing method can be used. Store seeds dry, and sow in spring the following year.
Division propagation
During growth, Sorbaria sorbifolia has the characteristic of easily sprouting root tillers, so division propagation can be carried out in early spring in March-April. Choose robust growing plants without pests or diseases and with many tillers as the mother plant.
The method is: dig open the soil around the roots of a mother plant over 5 years old, cut down from the middle of the gap with a knife, separate the tillers from the mother plant, and each clump can be divided into 5 to 7 plants. The separated root tiller seedlings must have complete roots. If the lateral roots of the root tiller seedlings are thin and numerous, appropriately cut off some when planting. This propagation method has a high survival rate, quick results in forming plants, and is relatively simple in management, but the number propagated is limited. After division, water sufficiently, and move the plant to a slightly shaded place. After one week, gradually place it in sunlight for normal care.
Cutting propagation
This method is suitable for mass propagation and can be carried out all year round, but cuttings root fastest in March and October, with a high survival rate. For the cutting soil, generally use 5 parts garden soil, 4 parts humus soil, and 1 part sandy soil, mix and make furrows and beds for open-field cuttings. For cuttings, choose current-year or two-year-old mature branches from robust plants, cut them to 15 to 20 cm long, and keep 4 to 5 buds or leaves. When cutting, insert 2/3 of the cutting into the soil, leaving only the top one or two buds or leaves above the soil surface. The cut on the cutting should be flat, cut into a horseshoe shape, insert as you cut, press down the soil at the base of the cutting, and water thoroughly once. After that, spray water 1 to 2 times a day and always keep the soil moist. After 20 days, reduce the frequency of spraying to prevent excessive moisture from causing the branches to rot. After about 1 month, they can root and be transplanted.
Layering propagation
In March and April, bend the branches on the outer edge of the mother plant directly down into the soil. The part pressed into the soil can also be ring-barked or notched to promote rapid rooting. After new roots grow, separate from the mother plant and transplant in the spring or autumn tree-planting season.
Disease control of Sorbaria sorbifolia
After the plants have grown, pest and disease control work should be carried out in time, and early control should be achieved to promote healthy plant growth. The main diseases of Sorbaria sorbifolia include: leaf spot, powdery mildew, and brown spot. The main insects to prevent include: scarab beetles, spotted leafhoppers, and others.
Leaf spot
When the disease occurs, round or irregular brown spots appear on the leaves, and sparse brown mold-like matter grows on the spots on the back of the leaves.
Control method: spray a 500-800 times diluted solution of 50% thiophanate.
Powdery mildew
When the disease occurs, white or grayish-white flour-like matter appears on the leaves. In severe cases, young tips curl, leaves become uneven, and fall early. Flowers are small and do not open, and the flower form is deformed, curled, and withered.
Control methods:
1. In late autumn, remove diseased and remnant plants to reduce the source of pathogens;
2. Pay attention to ventilation, reduce air humidity, strengthen light, apply more phosphorus and potassium fertilizer, and enhance resistance;
3. After the disease occurs, promptly cut off the affected parts, or pull out diseased plants and burn them;
4. Spray chemicals. During the dormant period, spray an equal-formula 1% Bordeaux mixture. In the early stage of disease, spray 70% thiophanate-methyl 800 times solution or 50% amobam 800-1000 times solution.
Brown spot
Sorbaria sorbifolia brown spot mainly damages leaves. At first, brown round to irregular lesions are scattered on the leaf surface, with darker edges and a clear boundary with healthy tissue. Later, sparse small dark brown to blackish-brown mold spots, namely the pathogen fruiting bodies, grow on the back of the leaves. The pathogen overwinters on affected leaves as mycelium or conidia. The following year it produces conidia that spread by wind and rain to neighboring plants. Generally, the disease occurs easily when tree vigor is weak or ventilation is poor.
Control methods
(1) From July to September, spray 65% zineb wettable powder 600 times solution or 70% mancozeb wettable powder 500 times solution, 25% benomyl emulsifiable concentrate, 12% copper green emulsifiable concentrate 600 times solution
(2) Strengthen management and improve disease resistance.
(3) In late autumn and early winter, collect diseased leaves and burn them in a concentrated manner to reduce the source of pathogens the following year.
Scarab beetles
Small green flower scarab beetles and others bite and eat leaves, flower buds, and flowers, causing leaves to become incomplete.
Control methods:
1. Taking advantage of the adults' death-feigning behavior, shake the branches in the early morning or evening to catch and kill them;
2. During the adult occurrence period, spray 40% omethoate 1000 times solution, or 50% malathion 1000 times solution.
3. Taking advantage of the adults' habit of entering the soil, scatter 2.5% phosmet powder around the plant. After application, loosen the surface soil so that the adults contact the chemical and die from poisoning.
Spotted leafhopper
Adults and nymphs often gather on the back of tender leaves to pierce and suck sap. Affected leaves show symptoms such as perforation, rupture, curling, or thickening depending on leaf age.
Control methods:
1. In winter, cut off overly dense branches and dead branches, and burn them to reduce the source of insects;
2. During the peak occurrence period of adults, use insect nets to catch and kill them;
3. During the damage period of nymphs and adults, spray 90% trichlorfon 1000 times solution, or 40% dimethoate emulsion 1200 times solution to kill them.
