What should I do if lilac does not bloom? How long is the flowering period of lilac?

1. What to do if it doesn't bloom

1. Supplement sunlight: The flowering of lilac cannot be separated from the effect of sunlight. If it does not see sunlight for a long time, it will naturally be difficult to bloom. You can move it to the sun for maintenance and nurture flower buds through photosynthesis.

2. Proper watering: Although lilac is relatively drought-resistant, it cannot survive without water, as it will lead to weak growth and inability to produce flowers. If you find that the soil inside is dry, water it in time, and water it appropriately during the growing period to replenish moisture.

3. Reasonable fertilization: The opening of flowers requires a lot of nutrients. If fertilization is not timely, they will not bloom without nutrient supply. If it is found that there is a lack of fertilizer, top dressing should be applied in time, and fertilizer and water management should also be done well at ordinary times.

4. Treatment of diseases and pests: If you do not pay attention to the maintenance methods during the maintenance process, the plants may be infected with diseases and pests, which will affect flowering. It is necessary to cut off the branches infected with diseases and pests, and then spray the corresponding pesticides.

2. How long is the flowering period?

Under normal circumstances, the flowering period of lilac is about two months, but there is a kind of four-season lilac, which has a longer flowering period, which may last from May to October, and the flowering period can last up to four or five months.
