How and when do I prune snowberry (Symphoricarpos albus)?
Symphoricarpos albus is a suckering plant, so you can literally prune it to the ground. It will probably come back healthier than ever (assuming it’s healthy at the time), especially if you do it in early spring. Snowberry can take over and will likely crowd out lower plants; keeping it in check can be done with a lawn mower, weed eater, or by hand pruning. I suppose you could shear it or selectively prune it, but to maintain its natural growth habit, pruning it to the ground is your best bet.
