What is the best fertilizer for hibiscus?

Hibiscus flower fertilization time

In spring, hibiscus should be fertilized after it sprouts, around mid-to-late April, mainly with quick-acting fertilizer, which can promote the healthy growth of the plant.

From May to October, two top dressings can be carried out during the peak flowering period, mainly applying phosphorus and potassium fertilizers, supplemented with nitrogen fertilizers. This can increase the number of flowers and maintain the growth shape of the whole plant. Finally, after the hibiscus flowers wither, the branches and leaves need to be pruned to accumulate energy for the winter, which requires appropriate fertilization.

What fertilizer is good for hibiscus

Hibiscus flowers are mainly fertilized with phosphorus and potassium fertilizers, supplemented by nitrogen fertilizers, which can prolong the flowering period, promote flowering, make the flowers more colorful, and sprout branches.

How to fertilize hibiscus

1. When putting it in the basin

When potting, base fertilizer should be applied to the bottom of the pot or in the soil. Since hibiscus does not require high soil pH, base fertilizer can be applied with confidence. It can be made by mixing decomposed livestock manure and compound fertilizer.

2. After germination

After germination, hibiscus will enter a period of vigorous growth, which is generally in mid-to-late April. At this time, quick-acting fertilizer is used mainly to ensure that the seedlings can absorb sufficient nutrients more quickly, which can promote the healthy growth of hibiscus and make the leaves greener.

3. Before flowering

Phosphorus fertilizer can be applied once before flowering, which can promote flowering, make the eyes more colorful, and promote weak plants to bloom.

4. Flowering

When flowering, you need to reduce fertilization. Generally, fertilization once every two months is sufficient. Fertilizer should mainly be compound fertilizer, which can effectively prolong the flowering period.

5. After the flowers fade

After the flowers naturally wither, the temperature will gradually drop and the hibiscus will slowly enter its winter dormancy period. Before winter, you can apply nitrogen fertilizer once to improve its resistance during the winter so that it will not be damaged by frost in winter.

Notes on fertilizing hibiscus

When applying fertilizer, be careful not to over-fertilize, and do not apply raw or concentrated fertilizer. Phosphorus and potassium fertilizers can be applied before flowering. During the flowering period, fertilization needs to be controlled. The temperature is high in summer and low in winter, which is not suitable for fertilization. You can reduce the number of fertilizations or stop fertilizing.
