Apparently propagating roses from cuttings is very common and can be quite successful but that is where the commonality seems to end. There are a variety of methods for doing so. First please be advised that it is illegal to propagate patented roses by any method.

In general it would seem that late fall (November) is a good time to take cuttings just after the rose has finished blooming. A cutting 6 to 8 inches long, with several nodes (eyes) and several leaves in place, should be pruned at a 45 degree angle to expose as much inner tissue as possible. Do so with a sharp knife or pruning shears. Also remove spent blooms and leaves from the bottom half. Do not let the cuttings dry out or be exposed to heat or cold as you undertake this process but get them quickly into rooting medium. The use of some kind of rooting hormone has been shown to be beneficial and will increase the chance of the rose rooting. (Fresh willow can also be used as a natural rooting hormone.) Then choose a place where the roses will receive bright light but shade from the hot or direct afternoon sun. A north or east facing garden bed is a good nursery site. Keep the cuttings well watered and by mid-spring you should have a rooted rose , which can then be moved to your desired location.

As far as winterizing roses, again there are many schools of thinking. Most wild roses and some native species are quite capable of handling the cold and wind in the winter months with many temperature swings. Hybrid tea roses on the other hand are not. The general guidelines are:

  • Prune the roses back before deep freezing sets in. Trim long canes and any material showing disease. (An anti-desiccant can be sprayed on the roses to help seal in moisture.)
  • Hill up the plants with dirt (pile it around the base of the plant) brought from outside the rose garden to the desired height. It should cover the center of the plant. Don’t pull the dirt away from the plants as you may expose crowns or roots. Adding mulch in the form of straw, leaves, pine needles or boughs on top of the dirt further protects the plants from any temperature swings. (We don’t want the plant to freeze and thaw as the temperatures change over the winter and early spring months.)
  • In the spring, when the ground has thawed remove the mulch and dirt and prune back any dead plant material

 

I hope that your roses, new or old,  live long, healthy and bloom-filled lives.
