Tropical Hibiscus Care Guide

Tropical hibiscus brings big, bold, exotic-looking flowers to Florida gardens and containers with relatively straightforward care. Here's how to keep yours thriving.

 

Sun and Location

 

Hibiscus needs at least 6 hours of direct sun daily to produce its best blooms. Morning sun with light afternoon protection works well in the hottest parts of the state, but most established plants handle full sun just fine. Choose a spot with good air movement to help prevent fungal issues.

 

Soil and Planting

 

Hibiscus prefers rich, well-drained soil with consistent moisture. Amend sandy Florida soil with compost or organic matter at planting time to improve water and nutrient retention. It also grows very well in containers, which makes it easy to move indoors or to a protected area during cold snaps.

 

Watering

 

Unlike many Florida-friendly plants, hibiscus likes regular, consistent moisture and doesn't tolerate extended drought well, especially in containers. Water deeply when the top inch of soil feels dry, more frequently during hot summer months.

 

Fertilizing

 

Hibiscus is a heavy feeder and blooms best with regular fertilizing. Use a fertilizer formulated for hibiscus or flowering tropicals, applied every 2 to 4 weeks during the growing season. Look for a formula with more potassium than nitrogen to support blooming over leafy growth.

 

Pruning

 

Regular light pruning encourages bushier growth and more blooms, since hibiscus flowers on new wood. Prune after a bloom flush or in late winter to shape the plant and remove any leggy growth.

 

Cold Protection

 

Tropical hibiscus is not cold-hardy and can be damaged or killed by freezing temperatures. In North and Central Florida, container plants should be brought indoors or to a protected area during cold snaps, and in-ground plants may need frost cloth covering.

 

Common Problems

 

Yellowing leaves are usually a sign of inconsistent watering or a nutrient deficiency rather than disease. Bud drop can happen from sudden temperature swings, moving the plant, or underwatering. Aphids and whiteflies occasionally appear and are treatable with insecticidal soap.
