Hybrid tea roses are among the world's most favored roses, and for good reason. They're beautiful, low-maintenance plants with blooms that fill the air with sweet aroma. Although it's crucial to protect hybrid tea roses from cold weather damage, don't be in a hurry. Let the roses survive a few freezing nights and protect them after the leaves turn brown and drop off.
Make sure your hybrid tea roses are healthy and well-maintained. Keep them properly watered and pruned. Fertilize them regularly throughout the growing season, using a fertilizer formulated especially for roses. Healthy roses will be stronger and more able to withstand cold wind and freezing temperatures.
Decrease fertilizing gradually in mid-summer and stop entirely by the end of August. Fertilizing at this time will encourage new growth, which will be tender and more susceptible to damage. Give the roses a deep watering before you expect the first freeze.
Prune to remove any broken or diseased canes but don't prune severely until spring. Clean the area around the rose and rake up dry and dead leaves.
Tie the tips of the hybrid rose together loosely with strips of fabric, soft twine or nylon stockings. This will provide support and prevent damage caused by wind. Shorten any canes that extend beyond 36 inches.
Create an 8-to-10-inch mound of compost and soil around the bottom of the hybrid tea rose. Bring the soil from another part of your yard and don't risk damage to the roots by loosening the soil under the rose.
Add a 12-to-16-inch pile of mulch such as straw, sawdust or bark over the top of the soil and compost. If you live in an extremely cold climate, you can provide additional protection by building a three-foot cage from fencing or chicken wire. Pile the mulch loosely in the cage.
