Climbing Roses
Climbing roses are a fantastic way to bring colour and charm to a bare wall, arch, fence or pergola. Climbing roses produce main canes and side shoots, the main canes are the backbone of a climbing rose, the side shoots produce the flowers.
The secret to successful climbing roses is to train and prune to encourage side shoots. Train the main canes of the rose horizontally, across rather than straight up. This may mean a ladder effect, ‘across and back’. It is best to tie or clip the canes to the support, rath er than weave, this makes it easier to prune back dead canes.
Those climbing roses whose names start with ‘Climbing’ are sports (genetic mutations of the bush varieties of the same name). They generally have a heavy spring bloom followed by scattered blooms throughout the season. The individual rose blooms on climbing roses can be of a finer quality and larger in size than those on standard rose bushes. Climbing rose bushes whose names are not prefaced with ‘Climbing’ are bred by crossing two rose bush varieties.
They generally have a heavy spring crop of rose blossoms followed by a repeat bloom and usually a good fall crop of rose blooms with a few exceptions. Climbing roses are a diverse group with many different heritages, which makes this a wonderfully useful collection of roses. Climbing roses have wonderful color in the rose garden without taking up much ground.
Climbing roses vary in winter hardiness. Generally, the climbing rose varieties are hardy zones 5 or 6 through 10 except as noted, some with more or less hardiness as noted.
Size: The first step is to determine how much room the rose will have to climb or ramble. Do you want a monster vine that will climb 30 feet, up onto the roof? Or do you need a delicate, well-mannered rose to cover a six-foot arbor over the garden gate? Many people make the mistake of choosing a rose they happen to like even though it wants to grow 25 feet or more, thinking they can keep it cut back to fit a five-foot trellis. This simply will not work. The constant pruning needed to keep it under control will butcher the plant, prevent it from blooming, and exhaust the gardener.
Shade Tolerance: Once you’ve determined the ideal size for your rose, the next thing to consider is the amount of sunlight that will reach the site. Although most roses need full sun and heat to bloom and stay healthy, there are a few climbers that will thrive in partial shade. In general, though there are exceptions, the white, light pink, and light yellow roses can tolerate more shade, while the reds, oranges, and stronger colors need more sun.
Disease Resistance: Even if you like to spray your roses (which I don’t!), it can be very difficult to reach all the leaves on a climber that’s tall and massive, so starting out with a healthy variety can save you a great deal of trouble. It’s also important to choose disease resistant varieties if you’re planning to grow the rose along a wall (which greatly reduces air circulation), or if you’re planning to grow it in partial shade. Roses on a chain link fence or on top of a pergola in full sun will have fewer fungal problems than roses on a north wall, which will need to be chosen with great care.
Rebloom: Many climbing roses, particularly the old Ramblers, bloom only once in the spring, while others will continue to bloom spring through fall. If this rose is going to be the star attraction in a small garden, you probably want to choose one that will perform for more than a month or two. But if you have room, many of the once-bloomers are so beautiful they’re worth growing for their annual spring show.
Many climbing roses will repeat with much greater frequency if given adequate water, fertilizer, and sunlight.
