I have had this situation with other evergreens. You can take a broom to gently knock the snow off. A blower also works well. Obviously delicately, lest you break something off. It will probably be fine leaving alone unless you get some freezing rain on top of it.

Melissa, I live in northern Oklahoma, about 4 hours from Dallas.

I worry about the ice and snow breaking the branches, and we go under the roses from time to time, lift them, and put in rebar. We estimate the height that we need, my husband bends the rebar, and we have put it under Mrs. B.R. Cant, Cramoisi Superieur, Monsier Tillier, and Duchesse de Brabant. We don't worry about Penelope and Ballerina since theiri branches are large. And we don't worry about the Carefree Wonder, Delight, etc. that can be easily cut back.

When we insert the rebar under a large rose, we have to carefully lift the entire area of the rose to get the rebar posts far enough into the ground. This is not a fun project.

I grow roses on an exposed hill top and most of my winds are from the west. I don't tie the roses up or anything like that. They mature accustomed to being buffeted by winds. Maybe that makes the canes more elastic.
More damage is done by someone (who shall remain nameless) who doesn't slow down when he zips by on his rideing lawnmower and I do get canes with longitudinal breaks from his lack of patience. Good news is that that teas can live with longitudinal breaks in woody canes. (Bad news is that this has happened often enough, that I can report this as a fact.)

This winds probably are the reason I don't worry about snow weighing down the canes.

We don't get snow very often, but occassionally get freezing rain & sleet during the winter. And it can get pretty windy here.
Because of the above, I can sometimes have winter problems with damage to my tea roses when they are young.
The young, flexible canes can be bent way down or even broken.
My tea roses barely go dormant at all, and our long growing season means that lots of new growth has usually been produced by the teas until very late in the year, just before potential ice can occur.
But after about 5 years, when the tea roses have built a solid structure, they begin to hold up well to the occassional winter storms that we have.
For example, my Mrs. Dudley Cross used to be very scared of winter freezing rain & ice. Now, she's a seasoned, portly lady and doesn't blink an eye.
Same for Mr. G. Nabonnand.

Last winter here we got a very heavy, wet snow about 12" but the roses were fine. Had plenty of damage to other plants but all the roses recovered well on their own.

Thanks for the input, folks, and it sounds like my non-strategy ought to work. In fact, the roses that are biggest and most squashed are those that have the protection of a wall. It's my experience as well that Teas recover quickly from the loss of canes, and fill in any spaces that open in the plant with new growth.

Ann, those who shall be nameless can be a trial, can't they? Mine has the faults of his virtues, as they say in French; he gets the job done where I would be dillying and dallying, but at the cost, at times, of a certain neglect of details. The garden wouldn't exist without him, though, and all in all he's a treasure.

My teas just went through a week of temps in the low twenties at night with seven inches of snow draped over them. For the most part there does not seem to be any damage to any of the bushes. They get more damage from wind I think.

Lance, did your roses go into this weather fully covered with leaves?

In my experience, rose canes do better under snow & ice pressure than most trees aka Leland Cypress and Arborvitae. I worry more about them than the roses.

Barbara

No snow here, though occasionally I can see it on the top of Mount Hamilton across the bay.

I actually hihacked this thread to tell Melissa that I sent her an email.

Thanks, Paula!
