Care for a hibiscus plant by placing it in a sunny location, composting the soil and watering it well. This plant also needs to be fertilized regularly during the growing season and pruned to manage growth.
Select a site for your hibiscus plant that is exposed to full sun and has well-drained soil. Because the plant can grow up to 15 feet tall, make sure that the site has plenty of room for future growth. The hibiscus can also thrive in a growing container. If the climate in your location drops below 32 degrees Fahrenheit in the winter, keep the plant in pot that can be brought indoors. You can move the pot back outside once the temperature is above freezing, although the plant grows best in temperatures between 60 and 90 degrees Fahrenheit.
Before or after planting the hibiscus, work compost into the soil to add nutrients. Make sure the plant gets at least 1 inch of water per week if rainfall isn't sufficient. Fertilize the plant twice a month using a high-potassium fertilizer. If you use diluted liquid fertilizer, feed the plant every week. Cease fertilizing after the growing season. Prune the plant regularly to the nearest side shoot to manage the growth.
