2. How long is the flowering period?

There are many reasons why lilacs do not bloom. If it is due to lack of sunlight, they need to be moved to the sun for maintenance and germinating flower buds through photosynthesis. If it is due to lack of water, water it in time when the soil is dry, and water it appropriately during the growing period. If it is due to delayed fertilization, timely top dressing is required, and fertilizer and water management also need to be done regularly. If it is due to infection with diseases and insect pests, cut off the branches infected with diseases and insect pests, and then spray pesticides accordingly.

1. What to do if they don’t bloom

1. Supplement sunlight: Lilacs cannot bloom without sunlight. If they don’t see sunlight for a long time, it will naturally be difficult to bloom. It can be moved to the sun for maintenance, and flower buds can be produced through photosynthesis.

2. Proper watering: Although lilacs are relatively drought-tolerant, they cannot be planted without water, which will cause the growth to weaken and the flowers to be unable to germinate. If you find that the soil inside is dry, water it in time. Water it appropriately during the growth period to replenish the moisture.

3. Reasonable fertilization: The opening of flowers requires a large amount of fertilizers. Nutrients, if fertilizer is not applied in time, it will naturally not be able to bloom without nutrient supply. If it is found that there is a lack of fertilizer, it needs to be top-dressed in time. Fertilizer and water management also need to be done well.

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

2. How long is the flowering period

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