Hibiscus plants are known for their large, colorful flowers that really make a statement in any garden But did you know these tropical beauties can also be grown as houseplants and enjoyed indoors? In this article, we’ll look at how to successfully grow hibiscus plants both indoor and outdoor.
A Bit About Hibiscus
Hibiscus belong to the mallow family and are native to tropical and subtropical regions around the world. There are several hundred species, but the most popular varieties for ornamental use are in the Hibiscus rosa-sinensis group. These hibiscus are prized for their showy flowers that can grow up to 6 inches across. The flowers come in a range of colors like red, pink, yellow, orange, purple and white. They have a prominent central stamen that gives them an exotic, tropical look.
Hibiscus are fast-growing shrubs in warm climates. Outdoors, they can reach 6 feet tall and wide within one to two years. The leaves are glossy and green, providing a nice backdrop for those gorgeous blooms Hibiscus flower during the summer and fall, but can bloom year round in tropical areas.
Growing Hibiscus Outdoors
If you live in USDA plant hardiness zones 9-11, you can grow hibiscus outdoors year-round. They thrive in the warm temperatures, full sun, and moderate humidity of these climates. Space hibiscus plants 4-6 feet apart in well-draining soil. Water them regularly to keep the soil consistently moist. Feed monthly with a balanced liquid fertilizer during the growing season.
In zones 8 and below, hibiscus can be grown outdoors in summer but must be brought inside before the first fall frost. Select a spot that receives full sun. Plant in rich, humusy soil with good drainage. Water whenever the top inch of soil becomes dry. Fertilize every 2-3 weeks to fuel growth and flowering.
To get your hibiscus ready for its move indoors, prune back leggy stems in early fall. This will make the plant more compact for indoor living. Stop fertilizing 6 weeks before bringing it inside to harden off the growth
Always check first and last frost dates for your area so you know when it’s time to bring hibiscus back inside. Even a light frost will damage the foliage and buds.
Caring for Hibiscus Indoors
The key to growing hibiscus as a houseplant is providing plenty of bright, direct light. A south or west-facing window is ideal. Turn the plant periodically so all sides get sun exposure. Supplement with grow lights if needed.
Indoors, hibiscus prefers daytime temperatures of 65-75°F and nights around 60°F. Keep humidity around 40-50% if possible. Water thoroughly when the top inch of soil dries out, taking care not to overwater. Drainage is critical to prevent root rot.
Fertilize monthly during the active growing season with a balanced houseplant food. Stop feeding for 2 months in fall and winter when light levels and growth slow down.
Prune back overlong, leggy stems to keep plants full and compact. Pinch off spent flowers to encourage more blooms. Wipe leaves periodically with a damp cloth to keep them dust-free.
With the right care, hibiscus will reward you with gorgeous, tropical flowers even when it’s cold outside! They make a stunning and conversation-starting houseplant.
