II. Cultivation methods for potted lilacs
1. Choosing a pot
The plant of lilacs is relatively large, with strong roots, so a deeper ceramic pot should be chosen, square or round both work. The color of the pot should be light blue or light yellow, which matches the white and purple lilac flowers better.
Select strong lilac seedlings and plant them in the pot from February to March. Trim the roots before planting, retain more fibrous roots, ensure the roots are spread out when planting, press the soil firmly, and let the soil and roots integrate closely. Then water thoroughly.
2. Watering
Lilacs are highly adaptable and relatively easy to care for. Just pay attention to weeding in time, water when the potting soil is dry, and avoid waterlogging to ensure normal growth. As for the frequency of watering, there are no strict requirements, just 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 growing temperature is between 15-20°C. When the temperature is below 3°C, the plant will freeze and die.
Lilacs also enjoy plenty of sunlight but can tolerate some shade, so make sure to place the plant in a sunny location 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 potting soil, and promote the growth of new roots.
Every mid-March, before the lilacs sprout, prune the plant by cutting off dense, weak, and diseased branches and trimming the vigorous branches. After defoliation, another pruning can be done to keep the crown round and beautiful, which is beneficial for growth and blooming the following year.
III. Precautions for growing 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 stabilize the trunk of the lilac plant to reduce the damage caused by shaking.
2. Weeding
From July to October every year, weeding should be carried out to remove all the grass around the lilac plant, but do not throw away the grass. Instead, cover the grass on the plant, which can be used as green fertilizer. After the seedlings grow into large plants, you can prune them, cutting off 30 centimeters from the ground to help the growth of branches and leaves.
3. Growing environment
Lilacs like sunlight, moisture, but are drought-resistant, so do not water too much. However, during the relatively dry spring, you can water thoroughly once when the buds are sprouting and during flowering to store enough water. They require fertile, well-drained sandy soil, and do not require excessive fertilization, as it may affect flowering.
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, September, and October, clear the weeds around the lilacs in time, but do not use a hoe to turn the soil, which may hurt the roots. Pull the weeds by hand.
6. Pruning
After 3-4 years of planting, when the branches of lilacs age, a severe pruning is needed, cutting the above-ground part from 30 centimeters above the ground. After cutting, strong branches will soon grow, making the crown full, and the plant can bloom profusely the second year.
The above-sharing about when lilacs bloom the most and the specific contents of precautions for growing lilacs are for everyone's reference and operation.
