I’ve got obscenely large mounds of liriope in my front garden as a border, and I was told to cut them back in early spring to allow for new growth. How far down do I cut them? They are ridiculously thick, as I don’t think they’ve been cut down or thinned out in several years. I’m planning on dividing and moving some of them to another area - what’s the best way to do that? Pre-trimming? Post? Skip the trimming if I’m moving them? I’m a relative novice to gardening, so please feel free to dumb down the instructions.
Also - irises. When can I move those safely? I have some in a weedy overgrown area of the yard and I want to put them where I can enjoy them.
