I grew these from cuttings I got from neighbors. I haven't put them in the ground because a passle of chipmunks in my yard dig everything up. I've also got tons of squirrels, wild bunnies, and a resident hawk! It's middle of September, so is it too late to move them anyway? Will they have time to set before it gets too cold, if the chipmunks don't uproot them? The Purple Heart are flowering, and the Sedum looks like it will soon. What should I do?
