Reasons why lilac does not bloom

1. Increase lighting

1. Reason: If the light duration in the environment where the lilac grows does not meet its requirements, it will be difficult for it to bloom because it cannot synthesize nutrients normally.

2. Solution: It is best to grow this type of plant in a sunny place so that it can absorb enough light to synthesize nutrients, which is conducive to flowering.

2. Proper watering

1. Reason: As the source of life, water is essential for the growth of lilac, and water shortage is absolutely not allowed. Improper watering can also cause the plant to fail to bloom.

2. Solution: Water the plants every day, but the more the better. An appropriate amount is enough. In other words, water them when they are dry, but don't water too much. This can solve the problem of the plant not blooming due to improper watering.

3. Add fertilizer

1. Reason: During the flowering process, the plant needs to be fertilized at regular intervals and in fixed quantities. Too much or too little will not work, otherwise it will cause the plant to fail to bloom.

2. Solution: Plants, like humans, require different nutrients at different stages. The flowering period of plants is like a person's adolescence, requiring more nutrients than usual. At this time, the plants need to be fertilized to avoid the problem of the plants not being able to bloom.
