What fertilizer should be used to make bougainvillea bloom? When should bougainvillea be fertilized?

1. What fertilizer to use

If you want to make Bougainvillea bloom, you need to apply some phosphorus and potassium fertilizers before it blooms. The amount of nitrogen fertilizer should be controlled. If you apply too much, it will not bloom. You can add some potassium dihydrogen phosphate to it so that it can bloom better after it has sufficient nutrients. If there is a lack of phosphorus, it will be difficult for the plant to form flower buds and it will not bloom. Stop fertilizing the plant after it grows flower buds, and do not fertilize it during the flowering period. However, do not apply concentrated fertilizer to it to prevent the appearance of fertilizer damage.

2. Which month to apply fertilizer

Bougainvillea needs to be fertilized during its growth period. It generally does not need to be fertilized in winter. It usually needs to be fertilized on schedule in spring, summer and autumn. From April to July, liquid fertilizer is mostly applied to it to help the plant grow more vigorously. From around August, phosphorus and potassium fertilizers should be applied.

3. Notes

1. If the temperature can be maintained at a normal level during the winter and the plant is still in a growth state, you can fertilize it appropriately.

2. If the soil is dry when applying fertilizer, you can apply fertilizer to it. If the soil is moist, do not apply fertilizer to it.
