I have 5 endless summer. I planted them almost 3 years ago. They are in a Sunny/partial shade area. They have done nothing since I've planted them. Very small and frail looking. Last year I got just a few flowers but they also were small and very fragile. They are in good new topsoil. Last year I fertilized them in an effort to get them to take off. I am about to dig them up and forget them, however I see new leaves coming out and will give them one more year. Does anyone know what the problem might be. Hydrangeas are my favorite and I am so dissappointed with their showing. Could I have fertilized them too much and if so what should I do this year.
PS. I also have some Dooley and they did wonderful. Except both plants had a greenish, with slight blue tint flowers but stayed mostly green. Can't figure that out also.
