What a fantastic idea. This summer I planted 63 comfrey plants on a new plot that that was very weedy and grassy. I first rototilled it, then tried to pull out as much of the grass as possible. I then used a heavy duty tarp and cut X's with a box cutter in 18" intervals. The comfrey is now coming up very well with very little weed pressure. Thank s for the post and your genius idea. #GetShitDone #Homestead #GrowNostr
