Lilac, also known as purple lilac, is a shrub with a strong fragrance. Its flowers are colorful and smell wonderful, making it an excellent choice for landscaping and courtyard planting. In recent years, with the growing demand for ecological environment and beautification of life, the planting area of lilacs has been expanding year by year. How to raise lilacs efficiently? This article will reveal the best methods for growing lilacs.
Choose a suitable planting location1. Soil requirements: Lilacs are not particular about soil, but prefer well-drained, fertile, and loose sandy soil with a pH value of 5.5-6.5.
2. Light requirements: Lilacs enjoy sunlight and should be planted in sunny areas. Insufficient light will affect the growth and flowering of lilacs.
3. Climate requirements: Lilacs are cold-resistant and can be planted in most parts of our country. However, attention should be paid to heatstroke prevention in southern regions and cold proofing and warming in northern regions.
Plant or propagate at the right time1. Planting: Generally done in spring, selecting mature and plump seeds, planting depth is 2-3 centimeters, keeping the soil moist.
2. Propagation: Select healthy branches, cut into 10-15 centimeters in length, insert into sand beds, keep moist, and roots will form in about 20-30 days.
Scientific fertilization1. Base fertilizer: Before planting, apply sufficient base fertilizer, such as decomposed organic fertilizer, compound fertilizer, etc.
2. Top-dressing: During the growing period, apply compound fertilizer once a month to supplement nutrients.
3. Foliar fertilizer: In the period of vigorous growth, spray 0.2% potassium dihydrogen phosphate solution to promote flowering.
Pruning and shaping1. Pruning: During the growth of lilacs, it is necessary to prune sick and weak branches, and dense branches to maintain a beautiful tree shape.
2. Shaping: According to the growth situation, prune in time to make the lilac tree crown neat and achieve better flowering results.
Prevention and control of diseases and pests1. Diseases: Lilacs are prone to leaf spot disease, root rot disease, etc. When diseases are found, it is necessary to cut off the diseased branches and spray 50% carbendazim wettable powder 800 times liquid for prevention and control.
2. Pests: Lilacs are easily invaded by pests such as aphids and red spiders. When pest infestations are found, spray 20% dimethoate emulsion 1000 times liquid for prevention and control.
Watering and drainage1. Watering: Lilacs prefer a humid environment. During the growing period, keep the soil moist but avoid waterlogging to prevent root rot.
2. Drainage: Dig drainage ditches around the planting site to ensure timely drainage of rainwater.
During the cultivation of lilacs, it is important to pay attention to selecting a suitable planting location, planting or propagating at the right time, scientific fertilization, pruning and shaping, prevention and control of diseases and pests, and watering and drainage, in order to make the lilac flowers more beautiful and add a touch of beauty to our lives.References:
