Why don't lilac flowers bloom?

1. Apply fertilizer with high phosphorus content 1-2 months before the lilac flowering period, and apply fertilizer according to the amount to prevent fertilizer damage. Applying phosphorus can promote the formation of flower buds, making it easier to bloom.
2. Excessive nitrogen fertilizer will cause excessive branches and leaves, resulting in excessive growth. Excessive nutrient consumption makes it difficult for flower buds to form, and the number of flower buds will lead to few or no flowers.
3. One month before flowering, you can control water to promote the formation of flower buds. Water thoroughly after the soil is completely dry. The alternating pattern of drying out and then being thorough can easily lead to the formation of flower buds.

What to do if lilac does not bloom

1. Get more sunlight: The flowering of lilac cannot be separated from the sun. If it does not see the sun for a long time, it will naturally not bloom. It can be moved to the sun for conservation and form flower buds through photosynthesis.

2. Watering in moderation: Although lilac is relatively drought-resistant, it is absolutely impossible to grow without water, which will cause the growth to decline and the petals to fail to form. Water it immediately when you find that the soil inside is ready, and water it in moderation during the growth period to replenish the water.

3. Effective fertilization: The opening of the petals requires a lot of nutrients. If fertilization is not done in time, there will be no balance of nutrient supply and demand and of course it will not bloom. If you find that there is a lack of chemical fertilizers, you need to fertilize in time, and you also need to do a good job of liquid fertilizer management on a regular basis.

4. Treatment of pests and diseases: If you do not pay attention to the maintenance methods during the maintenance process, the main stem may be infected with pests and diseases, which will affect flowering. The branches infected with pests and diseases must be cut off and then sprayed with medicines accordingly.
