Full Answer

  1. Clean and disinfect the tools

    To prevent the spread of bacteria and disease, clean your tools with an antibacterial household cleanser before and after use.

  2. Do seasonal pruning

    Prune Rosa rugosa after the last frost but before its blooming season begins when new growth is visible. Start by removing dead, withered, discolored or diseased branches. Cut the canes at a 45-degree angle away from the plant. Remove the suckers, which resemble fleshy outgrowths, from the base of the plant to stop unnecessary growth. Deadhead roses by cutting them to 1/4 inch of the next leaf cluster.

  3. Do renewal pruning

    Renewal pruning is done at the same time as seasonal but only every 2 to 3 years. Remove one-third of the oldest stems, working with clusters of four to five canes at a time from the base of the plant using loppers. Cut back each remaining cane between 3 and 10 inches.
