It is early spring but be sure to be on the lookout for AZALEA LACE BUGS. These will show up first on the lower foliage of your azaleas. The first generation starts around mid February and this visible damage starts showing up in April. Azalea lace bugs have 5-7 generations annually with another peak generation in August, September.
Control with horticultural oil, spinosad and similar contact insecticides or use systemic insecticides like acephate.
Plants in sun have more azalea lace bugs than plants in shade. Plants in stressed environments (reflective heat near sidewalks and parking lots) have more lace bugs usually.
