Problem Solver: Leaf Curl

If the leaves on your dwarf citrus are curling, there are three common possibilities:

  1. Some insect pests will cause some leaf curl. In spring, aphids might do this on soft new leaves. Look inside the curl for presence of insects. If none are present, consider 2 or 3 below.
  2. Overwatering can cause leaves to curl or cup INWARD. Also, stress from very hot weather will cause leaf cupping
  3. Sometimes leaves will cup DOWNWARD in the late fall or early winter. This is not a problem to worry about, as the new growth will come out with normal shaped leaves in the spring.
