Climbing and rambling roses are a wonderful addition to the garden. Arched over an entry or trellis, they bring color and interest above ground level. Among the most popular and carefree of the climbers is the New Dawn. With a moderate level of attention, this rose will provide generous blooms year after year.
Choose a site for your climbing rose that receives at least six hours of sunlight per day. While New Dawn is a bit more forgiving than some other varieties in this respect, it will grow faster and produce more blooms if it receives the optimum amount of sunlight. Plant your rose in the early fall or early spring.
Test your soil to gauge the pH level. This can be done by using a soil test kit available at your local agricultural extension office. Roses tend to grow best in soils with a pH between 5.5 and 7.0. If yours falls outside this range, you can amend the soil with lime or sulfur to urge the pH up or down. Consult with your extension office about application amounts based upon your soil test results, along with other mineral needs for your plant. Fertilize accordingly.
Tie the growing shoots of your climbing rose to a support in a horizontal position. The main shoots will then produce lateral stems along their length, ultimately producing a generous number of buds and flowers.
Use a soaker hose to give your rose about an inch of water weekly during times of low precipitation. The soaker hose is recommended because it gets water to the roots, where it's needed, without wetting the foliage. Wet rose foliage is more susceptible to disease and pests.
Prune your New Dawn rose just after the first flush of blooming in the spring. At this time, remove diseased or damaged canes. Make sure your pruning shears are sharp and make clean, angled cuts. Avoid anvil-style pruners with just one blade, as these may crush the stems as you cut. You might also clean the blades with a 70 percent alcohol solution to prevent the spread of disease.
Continue to care for your rose during the dormant winter months. Before the ground freezes, apply a thick mound of mulch around the base of the plant. Water monthly during the winter on a warmer day, allowing the water to soak down to the roots.
