When to mulch newly transplanted peonies
I am in Zone 5, Chicago area. I transplanted some peonies two weeks ago and a couple more last weekend. The news says we are supposed to get our first frost this week. I read somewhere not to mulch too soon--to wait until the first time the ground freezes.
Two questions: 1) is the first frost the same as the first time the ground freezes? 2) with the brand new (one week old) transplants, should I go ahead and mulch before the frost? They really haven't had any time to grow roots yet. I was planning to mulch with straw.
