Q: Should grasses that only get a few inches high, like blue fescue and carex, be cut back before new spring growth? Would now be a good time?
A: Unlike big grasses, such as pampas grass and maiden grass, the small evergreen grasses and sedges you noted don’t need annual pruning. I would simply wait until warm weather returns and check the plants for frozen tips. if found, it’s easy to clip off the damage and let them grow for summer.
