  • Aphids: These small, soft-bodied insects may infest the leaves and cause curling, yellowing, or stunted growth. Control them with insecticidal soap or neem oil.
  • Cedar rust: This fungal disease may cause yellow spots, blisters, or rust-colored spores on the leaves, fruit, or twigs. Remove infected parts and use fungicides if necessary.
  • Fire blight: This bacterial disease may cause wilting, blackening, or cankers on the branches or leaves. Prune the infected parts and use antibiotics if necessary.
  • Scale insects: These small, flat insects may attach to the bark and suck the sap, causing yellowing, wilting, or death. Control them with horticultural oil or insecticides.
