The Q&A Archives: Hibiscus Care

Question: My hibiscus in a container was happy last year and through the winter in doors. Now that is outside again some of it's leaves are turning yellow. It has only one bloom. What is wrong?

Answer: Yellowing can be a symptom of several issues. If you just moved it outside, it may be suffering from too much direct, strong sun. Move it gradually from a shaded area to the sun over about a week to ten days so it can adjust.

If the yellowing is primarily at the base, it may be dropping older lower leaves as it grows and develops new foliage at the growing tips.

Or, it may be responding to overwatering. Make sure your container has drain holes in the bottom.

Sometimes yellowing can be a sign of lack of nutrients. Use a water soluble or slow release fertilizer (such as 10-10-10 plus minors) per the label directions.

Yellowing can also be a sign of insect infestation. Check the plant carefully from top to bottom.

I hope this helps you troubleshoot.
