When Does Lilac Bloom
Here we introduce the blooming time of lilacs and share some experience about the maintenance of green plants during the flowering season of syringa. Next, the editor of this site will introduce to the netizens.
Lilacs, also known as purple lilacs, are common ornamental flowers. Additionally, lilacs are the city flower of Harbin, Heilongjiang Province in China. Many have heard of them but never seen them. So, when do lilacs bloom? How to care for potted lilacs? What are the precautions?
1. When Do Lilacs Bloom?
1. Flowering Period
The blooming time of lilacs varies by variety, but most bloom between April and May, as well as in autumn from July to August.
Lilacs have a large number of flowers, mostly white, purple, yellow, and other colors, with rich and bright colors and sweet fragrance, making them highly ornamental flowers.
2. Varieties
Ornamental lilacs: They bloom various colors in spring, mostly grow in temperate regions of China, and have great ornamental value, forming a sea of flowers that bring beauty to people.
Spice and medicinal lilacs: This type of lilac is a tropical plant, originally from the Maluku Islands and surrounding islands in Indonesia, commonly used for making spices and drugs.
Male lilacs: Male lilacs do not bloom and only have flower buds, which can be dried to make spices.
Female lilacs: Female lilacs refer to mature fruit of the lilac, which, like flowers, can be used to make spices.
II. How to Care for Potted Lilacs
1. Choosing a Pot
The plant of lilacs is relatively large, with strong roots, so a deeper ceramic pot, square or round, should be chosen. The color of the pot is preferably light blue or light yellow, which matches the white and purple lilacs better.
Select strong lilac seedlings and pot them in February to March. Trim the roots before planting, retaining more fibrous roots, ensuring the roots are spread out, pressing the soil firmly, and making sure the soil and roots are closely combined. Then water thoroughly.
2. Watering
Lilacs are highly adaptable, with a relatively rough care method. Just pay attention to weeding in time and water when the soil is dry, avoiding waterlogging, and they can grow normally. There is no strict requirement for watering frequency; just water when it's dry.
3. Temperature
Lilacs prefer a warm and humid environment, originally from the equatorial rainforest climate, with some cold resistance. The best growth temperature is between 15-20°C. When the temperature drops below 3°C, the plant will freeze and die.
Lilacs like plenty of sunlight but can tolerate some shade, so make sure to place the plant in a sunny area for maintenance.
4. Repotting and Pruning
Lilacs need to be repotted every 2-3 years, taking the plant out of the pot, pruning the roots, removing old roots, replacing with new potting soil to promote new root growth.
Every mid-March, before the lilacs sprout, they should be pruned, removing dense, weak, and diseased branches, and cutting back the vigorous branches. After the leaves fall, another pruning can be done to maintain a round and beautiful canopy, beneficial for the next year's growth and flowering.
III. Precautions for Caring for Lilacs
1. Protect from Wind
Lilac care should start from its youth, with wind protection measures during the seedling stage. You can use bamboo to stabilize the trunk of the lilac plant, reducing damage from shaking.
2. Weeding
Weeding should be done from July to October every year, removing all grass around the lilac plant. However, don't throw away the grass; cover it on the plant to use as green fertilizer. When the seedlings grow into large plants, you can do some pruning, cutting about 30 centimeters from the ground to help branch growth and lush foliage.
3. Growing Environment
Lilacs like sunlight and moisture but can tolerate drought. Therefore, do not overwater, but during the dry spring, you can water thoroughly once during the germination and flowering periods to store enough water. They require fertile, well-drained sandy soil and do not like excessive fertilization, which can affect flowering.
4. Repotting
Lilacs need to be repotted every 3 years or so, replacing new soil. When repotting, prune the roots, removing long and old roots.
5. Weeding
From July to September and October, clear the weeds around the lilac plant promptly, but don't use a hoe to turn the soil, which could injure the roots. Pull the weeds by hand.
6. Pruning
After 3-4 years of planting, the branches of lilacs age and need to be pruned strongly, cutting the trunk about 30 centimeters from the ground. After cutting, strong branches will quickly grow, making the canopy full, and the plant can bloom profusely the following year.
The above is a comprehensive explanation of when lilacs bloom and methods related to the flowering season of syringa, hoping it can act as a starting point to solve your green plant problems.
