I'm trimming back my EE's to the ground, as I always do. I usually don't do anything else to them, after I put a little mulch on them. They're so thick, though, and some of the biggest ones are so high on top of the ground. Do you guys pull those up and store them? And, if so, how? Do you pull a bunch of them up? Mine always do pretty good considering the north Texas sun, but I'm just wondering if they would do better if I really thinned them out. Please advise.
