Why are the leaves on my hibiscus plant curling up?
Curling Leaves on My Hibiscus
Certified GKH Gardening Expert
Generally, this is a sign of an insect infestation. Spider mites, mealy bugs, aphids, thrips, and whiteflies are common pests that affect hibiscus plants, sucking sap from them and resulting in anything from poor growth to leaf curl and drop. Thoroughly inspect the plant to see if this is indeed the problem and then treat the plant with neem oil. If you do not see any signs of pests, check the soil to ensure it is getting adequate moisture.
