black aphids on prunus trees

Kathy Hall asked 11 years ago

A few days ago I noticed that the leaves at the tips of the branches of two of my 3-year old cherry trees have curled, and inside the curl are what appear to be black aphids. I have sprayed with an insecticide but of course couldn’t reach the top of the trees. The aphids seem to have reduced but are not gone. Are the trees likely to overcome the problem?

Cherry blackfly is a form of greenfly or aphid, causes leaf curl and some withering. It lasts just a few weeks and is not a major problem, though unsightly.

It is not necessary to spray and trees cannot be sprayed in any case.
