Camellia Leaf Gall

This disease is caused by a fungus and is more common on Camellia sasanqua than on Camellia japonica. Leaf galls are most often observed during or just before the spring growth flush. The affected, off-colored leaves become thick, fleshy, and distorted. The galls later rupture on the undersides of the leaves revealing a whitish mass of spores produced by the fungus. The wind carries these spores to other plants. The galls eventually harden and become brown. Humid, shady conditions favor gall formation.

Control: Handpick galls and destroy before the lower leaf surface breaks and release spores. Avoid wetting the leaves when watering. Fungicides are available.
