What's the proper angle for rose pruning cuts?

Prof. Samuel Fitzgerald, Ph.D.The angle of your pruning cuts has a major effect on the health of your roses and the direction of their growth. Making precise 45-degree angled cuts just above outward-facing buds allows water runoff from delicate bud tissue. Rot is avoided, and new stems grow outward rather than crowding. Correct angles will promote healthier bushes over time.
Angled Cut Mechanics
- Position shears at 45° relative to the cane
- Slope cuts downward away from buds
- Allows rainwater to run off cleanly
- Mimics natural leaf-fall patterns
Bud Positioning Rules
- Always cut 0.25 inches above buds
- Select buds facing outward from center
- Avoid buds pointing inward or sideways
- Ensures balanced growth distribution
Problem Prevention
- Prevents water pooling on flat surfaces
- Stops fungal spores from colonizing cuts
- Reduces cane borer infestation risks
- Minimizes winter dieback at bud sites
Learning the angle takes a little practice. Hold your bypass pruners parallel to the angle of the cane before you cut. Imagine water running down the angle away from the buds. I practice with a few old canes I've discarded until the motion feels like second nature. With some repetitions of consistent angles, it becomes instinctual.
Unattractive angles cause permanent issues. Flat angles hold moisture, leading to diseases produced by fungi. Inward angles create dense centers with poor air circulation. I helped my neighbor with their rose problems by simply adjusting their cut angles. Easy adjustments made sickly shrubs into healthy plants.
For precise angled cuts, bypass pruners are the best choice. They make cleaner cuts than anvil types due to the scissor action. I always ensure my blades are razor sharp, so they slice through food easily. Dull tools rip stems, creating uneven angles. Sharp means I get to control the cut every time.
Some special cases may require some special considerations. For curved canes, you'll have to modify the angle along the cane's length. I turn the plant around so that its branches are pointing outward. For stems that are growing downward, cut above the buds that are pointing sideways. The flexibility here is that you keep the outward growth motto.
