A comprehensive introduction to how to cultivate lilacs to make them bloom and the planting and maintenance methods of green plants and flowers, next our site editor will introduce to you.
Lilacs, also known as common lilacs, are a common ornamental flower. The blooming time varies with the variety, but most bloom between April and May, and in the autumn between July and August. Now many friends are raising lilacs, often used to decorate living rooms or bedroom balconies. So how to cultivate lilacs? What are the key points of maintenance?
I. How to cultivate lilacs?
1. Soil
When planting lilacs in pots, it is recommended to choose acidic sandy soil with good drainage and rich in humus. For ground planting, choose a sunny and fertile place with a deep soil layer and good drainage.
2. Planting
When transplanting, try to take more soil with the roots to make it easier to survive. It is best to transplant in early spring before the buds start to move. Apply enough base fertilizer in the transplanting hole first, then cover it with a layer of soil before placing the seedlings and filling the soil. After planting, water thoroughly once, and then water 2-3 more times to make it survive.
3. Fertilizing
Lilacs should not be fertilized too much, as excessive fertilizer can cause the plant to grow excessively and affect blooming. Reduce or stop fertilizing after winter. You can dig a circular trench around the plant and put in decomposed fertilizer, which can avoid the impact of excessive fertilization on the plant while supplementing nutrients. During the growing season, no fertilization is needed, just apply a thin solution of decomposed fertilizer once in early spring and after blooming.
4. Watering
Keep the soil slightly moist when watering, and ensure that the soil is loose and well-drained after watering. Timely drain the soil to prevent waterlogging. When waterlogging occurs, prune the lilacs promptly, removing the yellow rotting branches and leaves. After planting lilacs for the first time, water thoroughly.
5. Shaping and Pruning
Before the sprouts appear in mid-March, shape and prune the lilacs, thin out dense branches, weak branches, and diseased branches, cut the vigorous branches in half, allowing the crown to be ventilated and well-lit. After the flowers fade and if not left for seeds, cut off the残花 along with the two buds below the inflorescence to reduce nutrient consumption and promote the growth of new branches and the formation of flower buds. After the leaves fall, another pruning can be done to maintain a round and beautiful crown, which is beneficial for growth and blooming next year.
II. Key Points of Lilac Maintenance
1. Light
Lilacs are a warm-season tree species that prefer sunlight. They can also grow in slightly shaded environments, but the resulting inflorescences are smaller and the flowers lack luster. Therefore, lilacs should be placed in areas with strong scattered light. However, avoid placing them in direct sunlight during summer, and spray water on the leaves several times in the summer.
2. Temperature
Lilacs can withstand short-term low temperatures of 56°C, but from a production perspective, the extreme minimum temperature should not be lower than 6°C, and the average temperature in the coldest month should not be lower than 15°C, which is suitable for planting lilacs.
3. Pest and Disease Control
Lilacs have few pests and diseases. The main pests are aphids, bagworms, and tussock moths. You can spray 40% omethoate emulsion 800-1000 times or 25% phosmet emulsion 1000 times to control them.
