Aphids devour my apricot tree every year. I water with soap and water and also add tons of lady bugs, but that doesn't seem to fix the problem. Any other ideas?
Mine as well. I have a variety of issues with my apricot: fireblight, cankers, and aphids. This year we heavily pruned the tree, trying to remove all branches that were sick or damaged. When the tree went into bloom, I noticed some weeping branches, which were early signs of blight, and removed those as well. With the disease under control, I have yet to see aphids this year.
