What fertilizer should be used for bougainvillea? Is the fertilizer buried directly in the soil?

1. What fertilizer to apply

1. When bougainvillea is still a seedling, its branches are still sparse and the plant is also small. At this time, it is necessary to apply nitrogen fertilizer 1-2 times to promote the growth of branches and leaves. You can then apply some compound fertilizer to make the branches and trunks of the plant stronger.

2. For mature bougainvillea, it is mainly necessary to apply compound fertilizer with balanced nitrogen, phosphorus and potassium, and phosphorus and potassium fertilizer, which can provide nutrients for the plant to bloom. Usually after new buds grow and new leaves emerge, it is mainly phosphorus and potassium fertilizers that are applied, which can promote the differentiation of flower buds and help the plants bloom better. Once it becomes a mature plant, do not apply large amounts of nitrogen fertilizer, otherwise it will not bloom.

2. Is it buried directly in the soil?

When fertilizing bougainvillea, you can bury the fertilizer shallowly in the potting soil, or you can dilute it with water and then pour it along the edge of the pot. You can use farmyard manure, compound fertilizer, or fermented organic fertilizer for fertilization. No matter which fertilizer you use, the concentration of the fertilizer cannot be too high. Also, when the temperature is too low or too high, stop fertilizing.

3. Notes

If you accidentally apply too much fertilizer, you can take the fertilizer out of the soil. But if it is diluted before watering, it can be diluted by watering with large amounts of water. Of course, if the situation is more serious, it is necessary to remove the plant from the pot and change the soil. If there are rotten roots, reasonable pruning is also required.
