I believe most grapes are pruned in late Fall after the fruits are done ripening, but if you're not trying to get fruit this year you can prune any time you want. Perhaps you should consider binding the vines to the wire so they won't fall off. Just be sure to use something that will not cut into the vines as they get bigger.

docgecko, The answer to all of your questions is yes. Just remember, vines grow toward the sun. So, stand on your deck and see where the sun comes up and sets where you have it placed. You will be doing alot of pruning on the honeysuckle! LOL!!! GOod Luck!

There is a fruit growing forum that may be of more help.

Thanks everyone for the thoughtful responses. Sheila, since they're 1st year I'm letting them be for now, but it's hard not to cut them back, they're so gangly Halloblondie, our climates are indeed very different, I can't imagine having to prune down to the ground...but good to know they spring back and look OK. Carol, I'm with you, not very fond of sprawling roses. If they continue being so gangly, several of them will get the shovel. Ben Britten and Gertie are very likely to go . Jude has been excellent in habit and bloom. Evelyn is somewhat promising, looks better with maturity. I understand Golden Celebration gets really big,so mine probably needs more time. Dizzylizzy, good to know a few varieties are well behaved, your climate is probably most similar to mine. I've had my eye on Falstaff, I've read its very good in heat. I'll probably start shaping more severly next sping.
