It sounds like you've hit your yearly quota of stress. Is it vacation time yet? I hope things get better.
The roses look great and that was a super deal on the mulch.
The heat killing roses? I'm confused. We've been in the 90's with high humidity (yuk) but it hasn't killed any of my roses. I HAVE had lots of blackspot though. Poor roses. But tell me more on heat killing roses----or give me a link to the thread. I'm curious if I should be doing something that I'm not.
