Tropical hibiscus adjusts to winter indoors

Question: I had two hibiscus trees in pots outdoors last summer and brought them in for the winter. I placed them in front of a sunny window, but now most of the leaves have turned yellow and fallen off. It does appear that new leaves are trying to grow. What should we do to keep these beautiful plants alive?

Hibiscus c Rojypala wikimedia commonsWhen you bring tropical hibiscus plants (Hibiscus rosa-sinensis) indoors, they respond to the lower level of light by dropping their leaves, so your plants are doing what is normal. You can see that the plant is healthy, because new leaves are already sprouting.

To keep it healthy while it’s indoors this winter, provide water when the soil dries out to within 1 inch of the surface and feed it lightly every few weeks with a high-nitrogen fertilizer. Watch for spider mites, and use insecticidal soap to keep them under control.

A hibiscus growing outdoors can grow to unmanageable size, so now might be a good time to prune it, and if the plant needs repotting, it’s a good time to take care of that chore, as well.

Return the hibiscus to its outdoor home when the weather warms up again in the spring.
