Rosa 'Radrazz'
Nursery Pro tip: Blooms March to Thanksgiving with a haircut in February. That's it.
The rose that changed everything for Texas yards — bloom from April to Thanksgiving, no spraying, no deadheading, and disease resistance the old hybrid teas never had. Single and double forms in red, pink, coral and yellow, 3–4 ft mounds.
Full sun — six hours minimum, eight is better. Good air circulation. Any soil that drains; work compost into the bed before planting. Space 3–4 ft apart.
Spring or fall. Hole twice the pot width, ball at grade, native soil plus compost, Root Stimulator, 3 inches of mulch kept off the canes.
Deep soak twice a week the first month, then once or twice a week all summer at the base — not on the leaves. Roses bloom on water.
Rose food or a balanced fertilizer in March, again in June, and a last feeding by mid-August. Stop after that so growth hardens off.
Cut back by about a third in mid-to-late February, before the buds swell, and shape lightly after each bloom flush. Every few years cut the whole plant to 18 in to renew it.
Rose rosette disease is the one real threat: witch's-broom growth, bright-red distorted shoots and excessive thorns. There is no cure — remove the whole plant, roots and all, and don't replant a rose in that spot. Aphids in spring (hose them off), blackspot only in wet years.
Mass along a drive or fence; underplant with lantana, salvia or liriope. Beautiful with crape myrtle overhead.
