I live in SE Wyoming. I have always loved lilacs, and the new place we purchased only had 1 bush. I have pampered it to a healthy plant. I planted 7 new plants last fall. 6 of them the rabbits ate off the new growth this spring before I caught them and corrected the problem. They are now coming up from the base and look very healthy. My question concerns the white bush I planted. It was about 3 ft. tall and leafed out this spring and had a few blooms. I thought it was a result of everything new. Now the blooms are accompanied with a few fuzzy brown growths, looks possibly like early die off of the blooms, and all of the leaves are curling and looking unhealthy. Not sure what to do. Thanks Nancy
