How to Care for Hibiscus Flowers

Overview

The hibiscus plant, with its large, beautiful blooms, is available in 220 different species, according to the Brooklyn Botanic Garden. In annual, perennial or tree form, a healthy hibiscus is always more resistant to insect attacks and climate changes. While the hibiscus is typically considered a hardy plant to zone five, it flourishes when soil and sun conditions are optimal.

Planting and Growth

Step 1

Keep newly purchased plants in partial shade for seven to 10 days. This will acclimatize the plant to full sun.

Step 2

Plant hibiscus plants in well-fertilized and loose soil, with a pH between 6.2 and 6.5. The chosen area should receive at least 50 percent sun throughout the day.

Step 3

Place indoor hibiscus in front of a south- or west-facing window with direct sunlight.

Step 4

Add mulch to the soil regularly to keep the soil organic. Mulch should be no closer than two inches from the hibiscus' trunk.

Step 5

Allow soil to dry before watering. For hibiscus plants in planters, water should disappear into the soil within a half-hour of watering.

Insect Protection

Step 1

Water the hibiscus plant thoroughly before applying any insecticide.

Step 2

Spray for insects in temperatures under 80 degrees Fahrenheit. The early morning or evening is best.

Step 3

Fill a spray bottle with a mixture of Orthene, unscented soap and fertilizer. Mist tops and underside of all the hibiscus leaves.

Step 4

Repeat application every five to seven days for heavy insect infestations.

Pruning Hibiscus

Step 1

Prune a hibiscus using sharp pruning shears from early spring to early fall.

Step 2

Make a cut one-quarter inch above an eye growing in the direction you wish to encourage new growth.

Step 3

Prune to encourage the growth of three to four main branches. Also, prune excess main branches, as well as weak or misdirected branches.
