Plant Food for a Hibiscus

Although the hibiscus is grown because of its large, tropical flowers, the American Hibiscus Society recommends against using plant foods that claim to be "bloom boosters." They also recommend that you keep away from high-nitrogen fertilizers, which will promote foliage growth at the expense of flowers.

Function

• Plant food helps the hibiscus build strong stems and healthy foliage. It is also responsible for the number and size of flowers.

Features

• Adequate nutrition for a hibiscus includes trace elements, such as copper and iron. Professional growers use 7-2-7 fertilizer, according to specialists with The Tropical Hibiscus.

Considerations

• The hibiscus thrives when it is fertilized frequently with a light solution. The American Hibiscus Society recommends growing the hibiscus in a slightly acid soil, with a pH of 6 to 7, to help the plant better absorb the nutrients in the fertilizer.
