Video: Black aphids on cherry

In late May, we see a fan-trained cherry tree that has set a good crop and has healthy leaves, but it is also showing a problem. The young leaves are curled up, as a result of black aphids. These can be a problem because of the damage that they cause to the leaves, and in addition, the sweet nectar that the aphids exude also attracts wasps. Infected shoots should be cut right out and placed in a basket and eliminated. Don’t drop the cut shoots on the ground because ants will take the aphids back into the tree so that they can continue to use them as a source of sweet nectar. An organic treatment for cherry black aphids is to spray the tree with a diluted solution of washing-up liquid, the same sort of dilution that you would use to wash dishes, to the point of run-off.
