It's possible that it's just trying to grow and get strong, but because of the cooler weather we've been having, it's not there yet. I'd leave it and see what happens.

I had 6 new canes coming out of my QE and now one of them is very droopy. Either the cold or something else got it.

could be light burn. If you have those lights on for warmth, you are probably also telling her that the days are longer and to start putting out new growth that is probably getting a little chilled. Just a guess, but then i have never seen lights strung on a rose, christmas tree yes.

thanks guys...the lights are actually along the fence and up in the top of the arbor for AMBIENCE not for warmth. Quite pretty when turned on....that is too funny. I'm sure hoping it will straighten itself out. Never saw it look that way before. April

Have the plants checked for verticillium (or other) wilts if you are pretty certain it is not environmental or pests.

Most areas have a plant disease clinic to which you can send your samples for testing.

In the meantime, practice the highest level of sanitation: keep your tools sharp and clean, and disinfect pruners (and other tools) between plants; don't work on the plants when they are wet; etc.
