“Un-wintering” your roses
“Un-wintering” your roses
Those of you lucky enough to be growing roses in the warmer regions of the country, you don’t have to be so concerned about getting your rose plant to survive the winter season. Your plants are already actively growing, and some are already seeing flowers.
In areas where roses go completely dormant and need protection, those roses are just starting to wake up.
We have found the best way to over winter Hybrid tea, Floribunda, Grandiflora, shrub roses, and climbers is to mound up the base of the plants with at least a foot of arborist wood chips, or mulch of any kind. This covers the bottom foot of so of the canes protecting the plants. Climbing roses that are not hardy should be carefully laid down and those canes covered with wood chips or mulch too.
Now that winter has finally receded from the northern areas it is time to pull that mulch away from the bottoms of the rose canes and get them pruned! Wear some good heavy gloves to protect your hands.
Hybrid Teas, Grandifloras, Floribundas, and many shrub roses all make flowers on NEW GROWTH. That means that these roses you are uncovering really do need to be trimmed so the plants produce the best flowers.
In these colder regions, we do not trim roses in the fall. We leave the rose branches (canes) alone until early spring just before they start to grow.
Older rose bushes that have been in place for many years you should take a bit of time with each plant eliminating any dead or brown and dry canes right down to the ground with a nice sharp pruning shears. Any nice green stems that are not broken and look healthy should be reduced to about 6-8 inches in height.
The new growth that develops from those 6-8-inch canes will produce nice strong stems with large and healthy flowers.
Any of the older shrub rose types that bloom on old stems should not be pruned now. Know what kind of rose you have before you prune. Some of these older native roses that bloom on last years growth will flower in June and when that stem flowers you cut it down to the ground and new stems arise from the ground. Those stems make next year’s flowers.
Climbing roses are a bit fussier in the more northern climates for sure. Very formally trained climbing roses that are trained over arches or trellises may need to have some professional advice based upon the variety to best know how to prune them.
In most cases Climbing roses will bloom on the stems from last year. Then the newest shoots from the ground may also produce roses on the tips of those newest canes later in the summer. When the oldest, fattest stems are done blooming after their first set of blooms, those stems can be removed as far down as the ground allowing new stems to take over that arise from the ground. In some cases, if you are trying to maintain cover of an entire rose arbor you may decide to leave more of the older wood in place, so the plant does continue to cover the entire trellis or structure it has been trained on.
The key is removing older and/or diseased stems leaving clean and healthy stems each year. Winter damage may make pruning decisions for you.
Clematis vines make and incredible companion plant that can be planted among climbing roses allowing the Clematis vines to mingle with the rose canes adding complementary or even contrasting colors to the rose blooms. Both the Clematis and the Rose can co-mingle quite nicely neither overtaking the other making them perfect companions to co-exist.
Roses love sun. The more sun, the more flowers you will see. Sun makes strong canes and sturdy flowers, and initiates reblooming roses quicker. Water the roots, do not water the leaves. Keeping the leaves dry will lessen the chance of foliar diseases. Mulch over the soil up to the rose canes will not only look nice, also reduces the incidence of soil born diseases.
Treating roses for insects can be done with organic options or if not many. Or if you are in an area that has a lot of pressure from insects you may want to consider using a systemic rose care option. Granular systemic rose care is applied to the soil, watered in, and the plant takes up the active ingredient to prevent bugs from chewing on those plants.
