I live in the Chicago area. I have had a bed of lilies of the valley for years, in my yard, about 4' wide x 15' long. This year was a hot, very humid summer. We had some rain, inconsistent, and I am pretty good at watering my yard, my containers, and so on.
Many of my lilies of the valley browned up and withered away already (mid Sep) while some are still looking good. Will the shriveled up ones come back in the spring time?
Can I transplant NOW the good looking ones from the back of the bed to the thinner areas -- if not now, when? And how deep down do you need to dig them out to transplant successfully?
Much appreciate any guidance you can provide. Thank you!
