My Aster plants are turning almost completely yellow already. One is yellow except the top few inches. Where it isn't yellow yet there were hundreds if not more of some light brown small bugs on the top sides of the leaves. I think I am going to just cut them right down to the ground, but wanted to know if anyone had experience with this or knew what's going on. They are New England asters, and usually bloom in September. Thanks
