Q.Fruit Tree Winter Washes
I have a plum tree that is producing fruit, but the leaves shriveled or curled almost immediately after the blooms fell. I noticed black spots inside the leaves, but nothing appeared to be alive. I found a Winter Wash that can be used to treat aphids, which can cause the type of curling I’m seeing, but I can’t find the wash in the US (simply called, Winter Tree Wash). Any other tips on how I can treat this tree to save both the tree and its fruit?
