I like the idea of planting clover as a ground cover, and I've seen a few people suggest it. However, I'm wondering about whether this will compete with blueberries and other bramble berries in the root zone?
I've got an additional limitation in that my blueberries/bramble patch is on top of my septic drain field. So, I can't plant anything with roots that go much deeper than the brambles'. I'll definitely be encouraging dandelions and rhubarb at the edge of the bramble patch (which sits in full sun atop a small plateau) and I'll be planting lots of acid-loving nutrient accumulators for chop-and-drop, but does anyone have any other ideas for working with shallow root limitations?
