Peaches are still blooming. I usually go out with a paintbrush and play the honeybee, pollinating the flowers. This year I'm not. There are usually way too many pollinated flowers, resulting in way too many fruits. Then they need to be thinned. Good peaches only happen if they are at least a hand width apart. That's a fat hand like mine. Maybe 6 inches.. That's for genetic dwarf peaches. If there is a lot of leaf curl, many if not all of the peaches are lost, and pollination was not worth the effort. The trees are lovely. If they did not have peaches, they would be sold purely as ornamentals. That is, except here in the Maritime Pacific Northwest, where ornamentals that get leaf curl are not needed. It lookes like the infestation could be small. It's on some leaves. Not all tips. Leave curl results in a very pretty appearance at this stage. The leaves have a maroon variegated edge and start to become curly. Evil is sometimes quite pretty. It usually gets worse as the leaves grow. Wait and see. Treatment now is not helpful. Maybe the midwinter copper spray was helpful. I try not to get my hopes up. It would be great if that method worked.
