Yes, I've had frost damage when the temps warm up early and then we get hit with a frost. Fortunately, we've never had a really hard frost or freeze to ruin them for the season. But, some have looked pretty ratty and smaller throughout the season! I'm fortunate enough to live in sand, so drainage isn't a problem in the spring. But, I'm sure I water more often than anyone that has good soil when it gets hot and dry. But, with my sprinklers set up just right, it's not a big deal to water.
Maybe somebody should post a few pictures from some of their collections from last year to warm us all up!
