Methods of繁殖 Syringa
The editor will explain the relevant content of Syringa propagation, the methods of Syringa propagation. Next, the editor of the website will introduce to the netizens.
Syringa can be propagated by several methods such as division, layering, grafting, cutting, and sowing. Generally, sowing and division are commonly used methods.
Sowing is carried out in early April. First, soak the seeds in hot water at 40-50°C for 1-2 hours, then mix them with sand at a ratio of one part seed to two parts sand, place them in a sunny spot, cover with straw or hemp bags, and water frequently to keep the bags moist. After about a week, the seeds can germinate and then be sown.
Division can be performed in March or November. Simply separate the stems and branches that grow from the base of the mother plant and transplant them elsewhere. Cuttings should be done in autumn. Grafting usually uses ligustrum or Fraxinus as the rootstock and performs high grafting, generally 120-150 centimeters above the ground. The scion and bud should be selected from good varieties of mother plants. It is also necessary to trim the new shoots of the rootstock in time to prevent the consumption of nutrients, which could lead to poor development of the scion and bud, overshadowing the main plant. Layering propagation is best done in February. When layering, thick branches should be treated with ring stripping. After the layering has taken root, it can bloom in 2-3 years.
Syringa is suitable for ground planting and can also be potted. When transplanting, the roots should be taken with as much soil as possible to ensure survival.
How to plant Syringa?
Syringa prefers sunlight, slightly shade-tolerant, moist but not waterlogged, cold and drought-resistant, generally does not require frequent watering. It requires fertile, well-drained sandy loam soil. If planted in a shaded environment, the branches will be thin and weak, the inflorescences short and loose, and the flowers will lack luster. If planted in poor soil, it can still grow, but the flowers will be few and far between, and the growth will be weak. Therefore, it is best to plant in a sunny, fertile, and deep-soiled location.
When planting, it is necessary to take the soil ball and cut some branches appropriately, then water thoroughly after planting. Every spring when the weather is dry, water thoroughly when the buds are germinating and before and after flowering. Syringa does not like heavy fertilization; excessive fertilization can easily cause excessive growth and affect flowering. Generally, applying a well-rotted manure once a year or every other year before winter can replenish the nutrients in the soil. After the flowers fade, if not saving seeds, the spent flowers and the two buds at the base of the inflorescence can be cut off, and some dense inner branches should be thinned to facilitate ventilation, light penetration, and a beautiful tree shape, which is conducive to promoting new branch growth and bud formation.
After defoliation, the diseased and withered branches, thin branches should be cut, and the crossed, overgrown, overlapping, and dense branches should be shortened appropriately to make the branches evenly distributed and maintain a round crown, which is beneficial for growth and flowering the following year. For ground-planted Syringa, it is especially important to drain and prevent waterlogging during the rainy season, as prolonged积水 can cause leaf drop and death.
The above specific introduction about the propagation methods of Syringa is hoped to bring some knowledge of flowers to flower enthusiasts.
