Lilacs are highly adaptable, with a relatively rough maintenance method. Just pay attention to weeding in time and water when the pot soil is dry without waterlogging, and they can grow normally. As for the frequency of watering, there are no strict requirements, water when it's dry.
3. Temperature
Lilacs prefer a warm and humid environment, native to the equatorial rainforest climate, with some cold resistance. The best growth temperature is between 15-20℃, when the temperature is below 3℃, the plant will freeze and die.
Lilacs like plenty of sunlight but can tolerate shade, so make sure to place the plant in a sunny place for maintenance.
4. Potting and Pruning
Lilacs need to be repotted every 2-3 years, remove the plant from the pot, prune the roots, cut off the old roots, replace with new cultivation soil to promote the growth of new roots.
Every mid-March, before the lilacs sprout, prune them by cutting off dense, weak, and diseased branches, and cutting back the vigorous branches. After defoliation, another pruning can be done to maintain a round and beautiful crown, which is beneficial for the next year's growth and blooming.
Three, Precautions for Cultivating Lilacs
1. Wind Protection
Lilac cultivation should start from its youth, and wind protection measures should be taken during the seedling stage. You can use bamboo to fix the trunk of the lilac plant to reduce the damage caused by shaking.
2. Weeding
Weeding should be done from July to October every year, removing all grass around the lilac plants. Do not throw away the grass, cover it on the plant, which can be used as green fertilizer. After the seedlings grow into large plants, appropriate pruning can be done, cutting off 30 centimeters from the ground to help branch growth and lush foliage.
3. Growing Environment
Lilacs like sunlight, moisture, but are drought-resistant, so do not water too much, but during the dry spring, water thoroughly during the germination and blooming periods to store enough water. They require fertile, well-drained sandy soil and do not like heavy fertilization, which affects blooming.
4. Potting
Lilacs need to be repotted and changed to new soil every 3 years or so. When repotting, prune the roots, removing long and old roots.
5. Weeding
From July to September and October every year, clear the weeds around the lilacs in time, but do not use a hoe to turn the soil, which may hurt the lilac roots, just pull the weeds by hand.
6. Pruning
After 3-4 years of planting, the branches of lilacs age, and the above-ground part should be pruned strongly, that is, cut off 30 centimeters from the ground. After cutting, strong branches will soon grow, making the crown full, and the next year, it can bloom luxuriantly.
