Rosa is a genus of about 150 species of deciduous (occasionally evergreen) shrubs and climbers noted for their beautiful, often fragrant, single, semidouble or double flowers which are borne singly or in clusters on often prickly stems clad with 5-9 leaflets often having toothed margins.
If you lay the canes horizontally along a wall or fence, New Dawn will burst into bloom all along the canes. From early spring until late autumn, when roses are vigorously growing, they will need about an inch of water every week. If it doesn't rain, then give each bush about four gallons of water once a week.
Care: Scatter organic granular fertilizer formulated for roses around the base in March and again in June. Work compost into the soil at planting. Keep consistently damp for best performance (water the soil, not over the leaves) but can go without water except in extended hot, dry spells.
Each year before the plant leaves out, trim your rose plant's shoots, so only a few nodes extend past the structural canes. Also, refasten the major canes to the structure if necessary. Continue to check that everything is securely fastened throughout the year, so no damage to the plant or structure occurs.
Plant bare-root New Dawn climbing roses in early spring, or potted bushes anytime up until frost. Bare-root roses establish themselves best when day temperatures are below 70 degrees Fahrenheit. Choose a spot that gets full sun.
