How to Cut Back Tree Roses

Pruning tree roses properly helps them thrive.

Tree roses, plants created by grafting a rose variety onto a long stem, can add striking beauty to any landscape. Tree roses typically need a significant amount of care but, for many gardeners, are worth any additional maintenance. Pruning tree roses is particularly important, since improper pruning can leave the plant vulnerable to pests and diseases.

Things You'll Need

• Pruning shears
• Pruning sealer

Instructions

1. Determine your purpose for pruning. Decide if you wish to establish a particular shape for the tree. Prune for a symmetrical shape, if desired. Cutting about 1/4 inch above a bud will ensure growth in the direction that the bud points. Determine how far you wish to cut back the branches. Wear gloves to protect yourself from thorns.

2. Prune all dead, diseased or broken branches. Make all cuts at a 45-degree angle just above the bud to stimulate new growth. Use pruning shears and make clean cuts. Cut back any branches that rub against other branches or cross into the middle of the crown. Prune any branches sticking out from beyond the crown to achieve a rounded shape.

3. Cut back any unproductive twigs to allow more nutrients to go to productive branches. Remove any growth from beneath the bud union.

4. Seal large pruning cuts with a pruning sealer to prevent insects from entering the plant at the wound site. Do this also to prevent dieback, a condition caused by fungi and bacteria.

Tips & Warnings

• Prune your tree rose annually to maintain its desired shape.
