What to do if bougainvillea doesn't bloom

1. Replace flower pots in time

1. Reason: One of the reasons why it does not bloom is that the flowerpot has not been changed for a long time. Because its root system grows very fast, when it grows vigorously, its roots can extend to several meters. At this time, there is insufficient space in the pot, which affects the growth and flowering of the plant.

2. Solution: Always observe the growth of the plants and replace the flowerpots in time according to their size so that the plants have sufficient growth space.

2. Increase Lighting

1. Reason: If it lacks light for a long time, it will affect the flowering of the plant.

2. Solution: Move it to a place with plenty of sunlight. The longer the sunlight exposure time, the more and brighter the flowers it will bloom.

3. Regular pruning

1. Reason: If its branches are too many and too dense, it will affect the transmission of nutrients and inhibit the growth of flower buds.

2. Solution: During the maintenance period, you can prune the plant appropriately according to its shape and cut off those branches that are too long, so as to ensure the normal transmission of nutrients.

4. Control water and fertilizer

1. Reason: If the amount of water and fertilizer is not properly controlled, it will directly affect the growth of the plant and prevent it from blooming.

2. Solution: At this time, you should control the amount of water and fertilizer before it blooms, and wait until the leaves wilt before watering. Then stop applying nitrogen fertilizer and just add a little phosphorus fertilizer to allow it to bloom smoothly.
