Roses come in a dazzling array of shapes, sizes, colors, fragrances and bush types. Grandiflora, Floribunda and Hybrid Tea roses, which can vary in height from 3 to 6 feet, are usually considered bush roses because their natural shape is to bush out. Proper pruning of bush roses can result in a healthier bush with more abundant blooms. The following are the basic pruning steps for all bush roses.

Difficulty: Moderately Challenging
Instructions

Things You'll Need:

  1. Step 1

    Plan to prune most aggressively during late winter/early spring, when the bush rose is dormant--all the leaves have dropped off, and there are no real signs of growth. At this time you should prepare to remove all dead or diseased wood, cut back the canes, and thin out twigs and thin branches. You will need pruning shears, lopping shears and possibly a pruning saw.

  2. Step 2

    Remove any canes that are crossing and on top of each other, and prune out spindly twigs and branches out the center of the bush to ensure light and air can circulate. Depending on your rose type and its location, you made need to cut the canes back to a height of 12 to 24 inches, shaping them to accommodate their location.

  3. Step 3

    Prune gently during blooming and growing season. Shape the plant by cutting back depending on what you want the bush to do. Look at the leaflet clusters. Rose leaves usually cluster in groups of 5 and 7. Each type of cluster results in a somewhat different growth patterns.

  4. Step 4

    Cut for new blooms. If you want to stimulate blooms, cut the rose branch at a 5-leaflet cluster. Prune about a ¼ inch above where the leaf stem meets the branch-the new bud is tucked in there. The resulting branch will be shorter and bloom sooner.

  5. Step 5

    Cut for new branches. If you want to stimulate new branch growth (which will result in new blooms at the end, but it will take longer) cut the rose branch at the 7-leaflet cluster. Prune about a ¼ inch above where the leaf stem meets the branch--the new bud is set in there.

  6. Step 6

    Keep an eye out for die back (branches turn yellow or black, then die) or diseased wood. This can happen throughout the season, and should be promptly removed.

  7. Step 7

    Clean up all debris and dispose of properly to avoid pests and disease wintering on the trimmings.

Tips & Warnings
  • When pruning, always prune at an angle to prevent standing water on the “open wound” of the branch. This helps it seal more quickly.
  • Some gardeners like to seal the open cuts on shrubs and bushes to minimize infection. For an environmentally friendly and child-safe option, consider using water-based Elmer’s glue.
  • Don't spray water on the bush immediately after pruning; you may increase the risk of infection on the “cut” because it literally is open. Give the "cut" a few hours to seal over.
  • Rose thorn scratches can become infected. Clean scratches with soap and water, and then apply a disinfectant or antibiotic ointment.
