Aphid populations spike during Kern County's peak summer heat, and the sticky honeydew they leave behind on leaves and branches often leads to sooty mold, a black fungal coating that makes a tree look far sicker than the aphids alone would cause.
The mold itself doesn't infect the tree directly, but it blocks sunlight from reaching the leaf surface, which cuts into a stressed tree's ability to photosynthesize during the hottest part of the year.
Ants are often part of the picture too, since they protect aphid colonies in exchange for the honeydew, so an ant trail up a trunk is sometimes the first sign something's off in the canopy above.
Noticed a sticky residue or blackish coating on the leaves of anything in your yard this summer?
