What fertilizer is good for bougainvillea

What fertilizer to use for bougainvillea

Bougainvillea needs nitrogen fertilizer once a week during the growth period and phosphorus fertilizer 2-3 times during the flowering period. In addition, it needs to be watered in time after fertilization to facilitate its root absorption. Of course, Bougainvillea has different requirements for fertilizers at different stages.

1. It is best to apply nitrogen fertilizer to Bougainvillea, which can promote the growth of new buds and leaves of the plant. It is especially suitable when the plant is a seedling. Applying nitrogen fertilizer once or twice after pruning can promote the normal growth of new buds, and at the same time make the branches and trunks of the plant thick and full, which will promote flowering in the later stage.

2. Soon after the new buds of Bougainvillea grow new branches, you should start applying phosphorus and potassium fertilizers. This can promote the differentiation of flower buds of the plant and make the plant mature and bloom as soon as possible. It is more suitable to fertilize the plant during its mature period.

How to fertilize bougainvillea

When fertilizing Bougainvillea, you can sprinkle some slow-release fertilizer on the surface of the potting soil to ensure the basic nutrient supply in the potting soil, so that it will not lack nutrients.

When fertilizing bougainvillea, you should apply thin fertilizers frequently. The interval between each fertilization should not be less than one week. When fertilizing, pay attention to whether the temperature is suitable. When the temperature is lower than 15℃ or higher than 33℃, stop fertilizing, otherwise fertilizer damage is likely to occur.

Spring fertilization

Bougainvillea should be fertilized in spring in March and April. Fresh water fertilizer should be used as the main fertilizer and an appropriate amount of fertilizer should be applied. The soil can be loosened before fertilization to help the plant absorb nutrients better.

Summer fertilization

After summer, new buds grow, and the branches and the entire plant begin to grow and develop, requiring greater nutrients. Fertilizer should be applied every 15-20 days. After fertilization, water can be applied appropriately to promote the dissolution of the fertilizer, which is beneficial for the plant to better absorb nutrients.

Fall Fertilization

After entering the flowering period, bougainvillea needs a lot of nutrients. You can increase the amount of fertilizer appropriately and water it in time after fertilizing to promote better absorption by the plant.

Winter fertilization

If you live in the north, the temperature is low in winter and bougainvillea will not grow. During this period, do not fertilize it. Keep the soil in the pot slightly moist to help it survive the winter safely.

Points to note when fertilizing bougainvillea

1. If bougainvillea causes fertilizer damage when fertilizing, if the situation is not serious, you can pour more water to flush it. If the situation is more serious, you can remove the pot and replant it.

2. Bougainvillea is a light-loving plant and likes to grow in sunny places. After fertilizing, it should also be placed in a ventilated and sunny place for maintenance, which can encourage it to absorb nutrients as soon as possible.
