Kitty Belendez has a calendar on the Santa Clarita Valley (CA) web site (scroll down the page to find "Exhibitor's Rose Care Calendar", it is a .pdf file). Adjust accordingly for your zone. Also see the article, "Pruning for the Fall Rose Shows" for info on when to prune.

Typically, HTs, grandifloras and floribundas will need a 45 - 60 day rebloom cycle (the more petals, the longer the rebloom cycle), minis/mini-floras 30 - 45 days, singles about 30 days. But, learn what the cycles are in your garden. Also you have to take weather into consideration, get a hot spell in the middle and you'll bloom early.

Thanks, Diane. You've been a big help.
