What fertilizer is best for hibiscus flowers?

Hibiscus flower fertilizer

Hibiscus likes fertilizer. Generally, when fertilizing hibiscus, potassium fertilizer should be used as the main fertilizer and phosphorus fertilizer as the supplement. It is best to fertilize hibiscus when it is potted, repotted, transplanted, growing leaves and flowering. It is usually best to apply decomposed liquid fertilizer, nitrogen fertilizer and urea to hibiscus.

Hibiscus can be grown with compound fertilizer. Generally, nitrogen-containing compound fertilizer or decomposed liquid fertilizer can be applied during topdressing. Hibiscus needs to be supplemented with some phosphorus fertilizer in time during the flowering period, and some urea or nitrogen fertilizer can be added after the flowering period.

How to fertilize hibiscus

1. When applying fertilizer to hibiscus, apply it thinly and frequently, and the concentration of the fertilizer should not be too high.

2. During the growth period of hibiscus flowers, it is necessary to apply decomposed and diluted fertilizer water.

3. When the hibiscus begins to differentiate flower buds, it is necessary to add 1 or 2 times of phosphorus and potassium fertilizers in time to promote growth differentiation.

Homemade Hibiscus Fertilizer

When fertilizing hibiscus, you can also make your own fertilizer. You can crush used bean skins, peanut shells, melon seeds, vegetable leaves or fruit peels, place them in a container filled with water, seal it, and place it in the sun for fermentation.

Fertilizer damage to hibiscus

When hibiscus flowers suffer from fertilizer damage, the leaves will turn yellow and in severe cases the flowers will fall off. At this time, you need to stop fertilizing, immediately fill the potting soil with water, cut off the affected leaves or flowers, and disinfect them.
