and do they go deeper than wide or wider than deep or is it about even? i realize it will depend on the size of the rose in question, so lets just say that it's for a big rose, a hybrid musk or a large shrub rose.
It's hard for me to answer that question definitively, Debi, because the gophers nibble on the roots of mine so much that I really don't know how big they might get if they were left alone, but when I've moved roses, I've sometimes had to dig down as far as a foot and a half, and about a foot and a half away from the trunk in all directions. Any roots sticking out or down farther than that get chopped off by my shovel. I don't think that's a bad thing. I know Kell grows some roses in pots and she actually pulls them out regularly and prunes the roots back to a manageable length when she prunes the bushes.
