How to Use Pruning Shears? | Clean Cuts Every Time

Guide / By

Use pruning shears by opening the jaws fully, seating the branch deep near the pivot, and squeezing the handles in one smooth motion.

Whether shaping roses or cleaning up spent perennials, technique comes down to a few habits: a sharp blade, the right cut placement, and one decisive squeeze instead of a sawing motion. Get those three things right and your plants heal faster and look better all season.

Position the Branch and Blade Correctly

Where you place the branch in the jaws matters more than most people realize. Set the stem as deep into the blades as you can, close to the pivot. Cutting near the pivot gives the most leverage and the cleanest cut; cutting near the tips invites twisting and mangled stems.

For bypass-style pruners, blade orientation determines where the clean cut lands. Bypass pruners have one sharp cutting blade that slides past a thicker hook. Put the sharp cutting blade on the side of the plant you want to keep, so the clean cut stays on the retained branch while the crushed side ends up on the removed piece. Grip the handles with the base of your hand and fingers, not just fingertips, to keep the cut controlled and prevent slipping.

Where to Make the Cut on Live Wood

Cut location depends on whether you’re working with live or dead wood. For live wood, cut just above a bud or node at roughly 45 degrees, sloping away from the bud, so water sheds off the wound instead of pooling. This helps the cut heal properly and reduces rot risk. For dead wood, spent flower stalks, or dry twigs, a straight cut works fine since healing concerns don’t apply the same way.

Avoid leaving a stub above the bud. Iowa State University Extension recommends cutting close enough to the branch collar or bark ridge that the wound heals well, but not so close that you damage the collar itself. A stub invites dieback and pests; a gouged collar invites decay. Also avoid cutting too far above the bud, a common mistake leaving an ugly dead tip.

Pruning shears are for small-diameter stems. If a branch is thicker than the tool’s maximum, switch to loppers or a saw. For larger branches, use the three-cut method to prevent bark from tearing: make an undercut partway through, then a top cut slightly farther out letting the limb break away cleanly, then a final cut at the collar to remove the stub.

Keep Blades Sharp, Clean, and Lubricated

Dull blades crush plant tissue instead of slicing it cleanly—an open door for disease that heals much slower. Sharpen only the sloped side of the cutting blade. Match the angle already ground into the blade rather than inventing a new one.

Clean blades before starting and again after finishing with warm soapy water and a scouring pad. If pruning plants with known disease issues, disinfect between cuts or plants with 70 percent isopropyl alcohol or a diluted bleach solution; rinse blades afterward since bleach corrodes metal. A light oil on the hinge and blades after cleaning prevents rust and keeps action smooth.

Safety, Common Mistakes, and the Right Tool

Wear gloves and safety glasses, cut away from your body, and ensure stable footing. Don’t reach awkwardly or balance on unstable positions just for one more cut. Keep shears away from children and pets, and engage the lock when setting them down.

The most common mistakes are easy to avoid:

  • Cutting with dull blades, which crushes tissue instead of slicing it.
  • Twisting or yanking the branch instead of making one clean, decisive squeeze.
  • Leaving a stub, cutting too close to the bud, or angling the cut wrong.
  • Using shears on branches too thick for the tool, bending or straining blades and joint.
  • Skipping sanitizing between plants that might carry disease.

Take less, spread work over multiple seasons, and plants reward you with healthier regrowth.

FAQs

Do I need to oil pruning shears after every use?

You don’t need to oil after every single cut, but a light coating on blades and hinge after each cleaning prevents rust and keeps the pivot smooth. Wipe off excess oil before storing, and reapply after washing with soap and water.

Can I sharpen pruning shears with a file or stone?

Yes. Use a flat file or whetstone on the sloped side of the cutting blade only, following the existing bevel angle. Use smooth, even strokes and avoid the flat back side, which would change the cut’s geometry.

How do I know if my pruners are bypass or anvil style?

Bypass pruners have one sharp blade that slides past a thick hook, like scissors. Anvil pruners have a single blade that closes onto a flat metal plate. For live green wood, bypass pruners give a cleaner cut; anvil pruners work better for dead, dry wood where crush damage matters less.
