I usually do try to prune this month (July) during the rainy season (now) so that they don't stay leggy. A lot of my roses start out the season (the whole 3 years I've been doing this, so 2 regrowing seasons!) leggy due to winterkill, so I have to prune drastically for spring (this year, almost down to the bud union/dirt for some.. that's how blackened the canes were). So I do a second pruning around now-ish so that they grow faster before winter hits. I don't mind losing a week or two or 3 with no buds.. I have enough other problems on my plate to worry about whether I get a bloom or two. In fact, almost every single rose that I have planted this year hasn't rebloomed yet for me until now.. so I'm not missing out on much. I do NOT prune in the fall because our fall is too unpredictable. It could be 80+ on Monday, 60 on Tuesday, snowing on Wednesday, then back in the 70s on Saturday. If I prune someone, I usually do a 1/3 cut, but that's only if the bush is too leggy/sprawly. If they've got leaves all the way down, or don't look like retarded saplings, I leave 'em alone.
