2. Weed Out the Bad Ones & Start Digging
Cut any bad peony stems down all the way to the ground and toss them aside. Then dig up the clump you want to divide with a spade around the perimeter, until the roots can easily be lifted out. Shake the soil from the roots. You should see the tuberous roots, large and small. There will also be a crown with plenty of “eyes” at the top. This mother plant can be divided into several new plants.
