Hi, all. I have a hole in my front yard, about 8-12" deep and 12-18" in
diameter. I was about to fill it in last year, when a giant Canna popped
out of it. I can't tell how deep it's actually planted, but the one
that's emerged seems to be growing out of the side of the hole, with an
air pocket beneath it. There are a couple more, which I believe are
growing out of the middle of the hole. I love the Cannae, but I hate the
pit in my yard. If I were to fill it in, would I endanger the plants?
