Trust me, I used to constantly worry about my plants in the early spring and the various fluctuations in Spring temperatures. At some point I began to realize that panicking got me nowhere. Our peonies break ground and can really take quite a hit with the weather. Lots of times you'll see them look a bit droopy after colder temperatures but once it warms up, having done nothing special, they rebound. They really are meant to take a whole lot in regards to weather. Overall, hail damage is one of those things you can't reverse that and a really hard freeze.... Below 20, at least that has been my experience here in the frozen tundra .
