Tropical hibiscus (variety: rosa-sinensis) can be grown outdoor year around in zone 9 and up. These hibiscus love the sunlight and heat. It doesn't tolerate cold weather. When the temperature drops to the 40s, some of the leaves will curl up and fall off the plant. If you are in zone 8 and below, it is best to bring the hibiscus indoor to overwinter. Or grow as an annual.
Container:
Transplant your hibiscus to 1-2 gallon container. Use any good potting soil. Make sure the containers have good drainage.
Sunlight:
Full sunlight -Or- Full morning sunlight and partial afternoon shade. Choose a location with unobstructed sunlight for several hours a day.
Watering:
Water generously after transplanting. The growing environment varies by region and seasonality. If you received your plant in the spring-fall, we recommend watering daily for the first week. If the temperature is in the 80s+ and sunny, water will be needed daily or every other day. It is imporatant to observe your plant to adjust watering accordingly. If your plant looks wilted, give your plant a good drench and increase frequency. It should perk back up. Observation is the best way to tailor the amount of watering it needs. In general, during the summer, water daily or every other day. Cut back during the winter.
Fertilizer:
Hibiscus are most actively growing when the weather is hot/sunny. Fertilizer in the spring and summer with a balanced slow release fertilizer.
