I've just had a number of very large shrubs and conifers cut down to ground level, leaving the roots and stumps. Unfortunately, I can't afford to have all these removed, but I need to re-plant the area with easier to manage shrubs and plants. I'm on my own and struggle with a bad back. Does anyone have any ideas or tips on how I can go about digging the area and re-planting around the roots and stumps? Is there something I can put in the stumps to prevent them growing again? The ground is very hard clay. TIA
