A rocky situation
This will be my fourth winter in WNY. Two years ago, I planted a wisteria in my front yard, planning on "tree shaping" it, which I've done before. I do provide winter protection as I know it's kind of "iffy" in this area. Here's my dilemma. What I hadn't realized when I planted it, was that there's a large rock (boulder?) right underneath. I hadn't had to dig down far enough when I planted to find it. I DID find it this winter when I went to pound in the stakes to support the winter protection (a mulch-filled Quick Tube) around the plant. The stakes would go down anywhere from 3 to 8 inches, depending on where I was in the yard, and stop. I could hear it hit rock, and no amount of pounding would persuade it to go any further. So I know my wisteria is planted right on top of it. Which also means that the rock is going to prevent the root system from growing down deep enough to go below the frost level. Frozen roots equal dead plant.
Question - should I go ahead and dig it up, while it's dormant, and replant it elsewhere in the yard (probing for underground rocks/boulders first). Or should I just leave well enough alone, cross my fingers and hope for the best? Am I worrying about nothing? LOL
I just haven't lived here long enough to feel comfortable in my knowledge of winter weather and plants. And this is a problem I've never had to deal with before. Any advice, opinions, solutions, thoughts would be appreciated.
