I have two Easy Going bushes (sport of Livin' Easy) that I moved to a new location in the garden 4 years ago. That year both adjusted beautifully to their move with no issue. The next summer a Livin' Easy bush grew where I had removed one of the Easy Going bushes...guess I didn't get all the roots out. It's still growing and flourishing as Livin' Easy. Last summer, one of the Easy Going's had a Livin' Easy bloom mixed in with all it's other blooms....only one all season...which was fine with me...kind of cool when that happens. This spring the same bush gave me a halfer and a Livin' Easy bloom together on the opposite side of the bush as last year's Livin' Easy bloom...which was fine with me...really cool when that happens. Now this weekend, the bush had a full new cane in the middle with all Livin' Easy blooms. I removed the cane, but am worried that it will continue to revert more and more. Is there anything I can do to prevent that?
