Blaze climbing rose, known botanically as Rosa x 'Blaze,' is a popular climbing rose cultivar that was first introduced in 1932. An ever-blooming rose variety, Blaze climbing roses are prized for their vibrant red, semi-double blooms that grace the plant from spring until the first fall frost. Blaze climbing roses can be successfully cultivated in United States Department of Agriculture (USDA) plant hardiness zones 4 through 10 with simple, basic care.

Provide your Blaze climbing roses with 1 inch of irrigation per week whenever rainfall is insufficient. Water climbing roses planted in sandy soils more often, if necessary, to maintain soil that is moist, but well-drained.
Spread a 3-inch layer of peat moss, pine straw or ground tree bark on the surface of the soil around your Blaze climbing roses to keep the soil moist and cool and suppress the growth of weeds. Add more mulch, as necessary, to maintain a 3-inch layer around the roses.
Fertilise Blaze climbing roses once a month from spring until the end of summer, while the plant is in its active growth phase. Feed your climbing roses with a specially formulated rose fertiliser, applied according to the directions on the product label. Cease fertilisation one month before the first projected fall frost.
Snip spent blossoms from your climbing roses with a pair of sharpened and sterilised pruning shears, as needed, to maintain the plant's appearance and encourage it to bloom again. Cut weak growth or suckers from the plant to allow it to focus its energy on producing healthy, beautiful flowers.
Prune Blaze climbing roses annually in the early spring to remove any damaged or dead wood. Prune the plant's lateral branches to control its size, if desired, by cutting them back to just three to four healthy buds.
Provide winter protection for Blaze climbing roses in cool climates. Form a 6- to 8-inch mound of peat moss or ground tree bark around the base of your climbing roses. Cover the rest of the plant with pine straw. Remove the mound and pine straw in the spring, before new growth is observed.
