Watering roses in cold weather?

I live in NY zone 6a and the roses look very dry. We didn't have precipitation for a while. Now the temps are 48-49 but at night they are forecasted in the 26-29 range. Should I water or not?

Should I water roses in dry cold weather?
Day temps are 49, but at night they'll fall to 27.
We hadn't have precipitation for a while.

In general, once the trees lose their leaves, the water doesn't go anywhere until spring. It just sits there going squoosh. For it to be a real issue, it would have to have not rained for more than a month, which means you somehow missed Sandy.

Not exactly. Some roses still have leaves and I planted a new one just a few days ago. Sandy took place 3 weeks ago. We had extreme winds but only 1" of rain.
The question is if 27-29 deg during nighttime is enough to damage the roots. Tomorrow, the temps will climb again to the 50 deg range.

The new one should have been watered in.

If it is temperature you are worried about, don't. Those nighttime temps shouldn't even bother leaves and canes. Roots won't even notice until the ground freezes at depth.

Thank you. I though it is something more people are interested to know, since such day/night temperature differences are common also in spring.

I continue to water right up until they go dormant. You don't want them to go into dormancy dehydrated because that further stresses them over winter. Well hydrated rose canes fair far better over the winter and come out stronger in the spring.

My roses are all still green and some of them even trying to put on some new growth so I watered everything Sunday when it was in the 50s and will probably water at least one more time before winter. If yours still have green leaves on them I'd say water them. Once the leaves have dried up they should be dormant and you can stop.

Here, if possible, you want roses to dry out a bit in the fall. Fall is usually our wettest season, and the modern roses have serious problems with this dormancy concept if they have plenty of water. So they grow and bloom, and then get the equivalent of a smack in the face with a hammer when winter comes.

This does assume that the soil is actually somewhat dry. I know mine isn't because I'm still waiting for the ten minutes of perfect weather when the grass catcher on the tractor can suck up the leaves and not jam.

Well obviously if it's raining like mad you don't need to water anyway. The roses will already BE hydrated, lol!

We haven't had more than a quarter inch of rain in the last month so my roses do need watering.

Mine do too. Water past the drip line before I mulch for winter...encourage roots to stretch for a drink.
