I had a tree service remove a large yucca plant and we want to grow a citrus in the empty spot. The yucca seems yo have left behind soil that feels almost like felt - very fibrous and woven. I'm guessing its either roots or decaying root matter. Do we need to remove the soil and replace before planting the tree?
