Red Twig Dogwood - Leaf spot
I put in a small row of Ivory Halo this past spring, and I have been plagued with leaf spot on all the leaves. I did not check the plants when I bought them. Did not know enough to do that. I have sprayed them with a lot of different things to no avail. If I start spraying early next spring will that likely be more successful? Once the fungus is in the soil near the plants am I doomed to a permanent problem?
