Just as I suspected...no "easy" fix. I hate to get rid of it because the humming birds LOVE it and all the other birds love it summer and winter. It's so pretty to see the cardinals in there during the winter. But I just can't take digging out all those suckers in the flower beds. Dozens and dozens every year. There is a large slab of cement right next to it. The cement has actually cracked an raised up a couple inches. I wouldn't be surprised if it is from the suckers running under the cement to reach to the flower bed on the other side (because they ARE there). It was planted in the center of a TV antenna tower about 10 years ago. We will have a time just getting it out of the tower.
I know I'll have to battle the suckers for years to come. But if I'm diligent I should, eventually, win the battle; don't you think?
