I have (what I was told) encore. There are 3-4 not sure of them in a very small area between the sidewalk and house. About 24" wide and 10 ft. long. A south east exposure. I feel they are to crowded and would like to move a couple of them or at least one.

I had to trim them back last fall ( they were growing over the sidewalk) and they didn't bloom much in the spring.

When can I move them? Were in NEOk. zone6.

Thanks.
