Plant Care
Light Requirement
Hibiscus plants thrive in full sun or partial shade. They need at least 6 to 8 hours of sunlight each day.
Water Need
Hibiscus plants require regular watering, especially during dry periods. They prefer well-drained soil and should be watered until the water drains out the bottom. However, they should not be left in standing water as this can lead to root rot.
Fertilizer
Hibiscus plants prefer a high-potassium fertilizer. An example of a synthetic option is a slow-release granular 12-4-18. Organic options include compost, manure or a balanced organic fertilizer. They should be fertilized once a month during the growing season and not at all during the winter.
Pruning
Pruning helps to maintain the shape of the hibiscus plant and encourage blooming. Pruning should be done in late winter or early spring before new growth begins. Remove dead and damaged branches and cut back the plant by one third.

Hibiscus plants are not toxic to humans, however, they can be mildly toxic to pets. If ingested, they may cause mild gastrointestinal upset.
Common Issues
