nandina filamentosa: can I plant it over a buried tree stump?
I just bought a very healthy looking (2-3 ft) nandina filamentosa in a big, deep nursery pot, and had my heart set on planting it in a spot where I could see it from the kitchen window. In the process of digging the hole, I discovered that a tree that had been taken out in that area (the stump above ground and down to about 8" below the soil line had been ground up) has left behind a very hard and solid stump or root in exactly the place I had wanted to plant the nandina.
Is there any hope that I could still plant the nandina there, in the soil above the part of the stump that was not ground up? There is plenty of room for the roots to go sideways, but I didn't take the plant out of the nursery pot to check what kind of roots it has. If it has a tap root, it would never work of course, but if it's shallow rooted, maybe it might??
