What is the best fertilizer for hibiscus?

Hibiscus flower fertilization time

The best time to fertilize hibiscus is during its vigorous growth period, because the growth rate is faster at this time, and sufficient nutrients are needed to ensure its normal growth. Around May every year, thin liquid fertilizer needs to be applied every 7-10 days.

What fertilizer to use for hibiscus

You can choose to use phosphorus and potassium fertilizers for fertilizing hibiscus, and make sure there is enough phosphorus and potassium fertilizers. The benefit of applying this fertilizer is that it can promote the continuous growth of flower buds, so that the plant can continue to bloom. In addition, it is better to apply calcium and magnesium fertilizers to the plant during the flowering period, which can make the flowers bloom more brightly and prolong the flowering period.

Hibiscus fertilization method

Hibiscus needs to be fertilized with thin liquid fertilizer every 7-10 days during its vigorous growth period. In addition, be cautious when fertilizing after autumn, and apply less fertilizer in the later period to avoid the growth of autumn shoots. This is because the tissues of autumn shoots are relatively tender and have weak cold resistance, and they are easily damaged by frost in winter.

Matters Needing Attention in Fertilizing Hibiscus

Do not apply too much nitrogen fertilizer during the peak flowering period of hibiscus, otherwise it will easily cause the plant to grow branches and leaves but not bloom. In addition, when using potassium dihydrogen phosphate to promote flowering, do not use foliar spraying, as this will easily cause flowers and buds to fall off.
