Alt text: "garden shears trimming a hedge in an urban garden setting"
Garden shears are the go-to cutting tool for shaping hedges, trimming ornamental plants, and tidying borders. These two-bladed tools work like oversized scissors, giving you wide cutting coverage in each stroke. Unlike single-blade pruners that cut one stem at a time, shears handle multiple thin stems at once. This makes them far faster for shaping tasks where precision on individual branches matters less than overall form. Urban gardeners use shears to maintain neat hedge lines, trim herb gardens, and cut back perennials at the end of the season. Pair them with pruning shears for a cutting toolkit that covers every trimming job in your garden.
What Is a Garden Shear
Garden shears consist of two long, straight blades joined by a central pivot bolt, with handles extending outward from each blade. The blades range from 15 to 30 cm in length depending on the type. Hedge shears have the longest blades for broad, flat cuts across hedge faces. Grass shears have shorter, lighter blades angled for cutting at ground level. Blades are forged from hardened carbon steel or stainless steel. Carbon steel holds a sharper edge, while stainless steel resists corrosion better. Handles are made from wood, aluminium, or fibreglass, often with rubber or foam grips for comfort. Some models include a shock absorber between the handles to reduce hand fatigue during long trimming sessions.
How to Use Garden Shears
Good shearing technique produces clean, even results and keeps your hands comfortable throughout the job. Follow these steps for effective trimming.
- Inspect and clean the blades. Before starting, wipe the blades with a damp cloth and check for nicks or burrs. Dull or damaged blades crush stems instead of cutting them. A quick pass with a sharpening stone restores the edge if needed.
- Position the shears correctly. Hold one handle in each hand with a firm but relaxed grip. For hedge trimming, keep the blades parallel to the surface you are cutting. Angle the shears slightly upward from bottom to top so the hedge tapers, allowing sunlight to reach the lower branches.
- Cut with steady, rhythmic strokes. Open the handles fully and close them in smooth, even motions. Let the blade length do the work rather than chopping with the tips. Move along the hedge face at a consistent pace. Avoid jerky or rushed movements that leave an uneven finish.
- Step back and check your line. After each pass, step back several metres to view the overall shape. Identify any high spots or uneven sections. Return and make targeted correction cuts. Working along a taut string line helps you maintain a perfectly straight edge.
- Clear debris as you finish. Shake cut material off the hedge face with a gentle sweep of the shears. Collect fallen clippings from the base and add them to your compost. Use grass cutting scissors for any fine detail work around the base of the hedge.
Maintenance and Care Tips
Sharp, clean shears give the best results and last the longest. Wipe sap and moisture from the blades after every use. Dried sap creates a sticky buildup that forces the blades apart and reduces cutting efficiency. Clean stubborn sap residue with rubbing alcohol or a purpose-made blade cleaner. Sharpen both blades evenly with a flat file or diamond stone, following the factory bevel angle. Oil the pivot bolt with a drop of light machine oil every few uses to keep the action smooth. Check the pivot bolt tension regularly. Blades that are too loose leave ragged cuts, while blades that are too tight strain your hands. Tighten or loosen the nut until the shears open and close with gentle, even resistance. Store in a dry location with a blade guard to protect the cutting edges.
Choosing the Right Garden Shears
Match the shear type to your primary trimming task. Hedge shears with long blades and straight handles work best for flat hedge faces and topiary. Grass shears with angled handles let you trim lawn edges without bending over. General-purpose garden shears with medium-length blades handle mixed tasks like cutting back perennials, trimming herbs, and light hedge work. Consider handle length and weight. Longer handles reach further but add weight. Lighter shears reduce fatigue during extended sessions. Test the spring tension before buying. Shears with adjustable tension let you customise the feel. Pair your shears with a garden trowel for a compact set that handles trimming and planting in small urban spaces.
Frequently Asked Questions
What is the difference between garden shears and pruning shears?
Garden shears have two long, straight blades that close together like scissors. They cut multiple thin stems at once and excel at shaping, hedging, and broad trimming. Pruning shears (also called secateurs) are single-handed tools with short, curved blades designed to cut one stem at a time. Pruning shears give you precision on individual branches up to about 2 cm thick. Garden shears cover wider areas but cannot handle thick, woody stems. Use pruning shears when you need to make selective cuts on specific branches, such as removing dead wood or shaping a fruit tree. Use garden shears when you want uniform coverage across a surface, such as flattening a hedge face or trimming a row of herbs. Most gardeners own both, as each tool excels at tasks the other cannot do efficiently.
How often should I sharpen garden shears?
Sharpen your garden shears after every three to four heavy trimming sessions, or whenever you notice the blades tearing instead of slicing. Dull blades leave ragged, brown edges on stems that invite disease and slow healing. To sharpen, disassemble the shears by removing the pivot bolt. Clamp each blade securely and run a flat file along the bevelled edge at the original angle, usually around 25 degrees. Count your file strokes to keep both blades evenly sharpened. Remove the burr from the flat side with a few light passes. Reassemble, adjust the tension, and test on a sheet of paper. The blades should slice cleanly without tearing. If you trim resinous plants like conifers frequently, you may need to sharpen more often because sap buildup dulls the edge faster than clean-stemmed plants do.
Can I use garden shears to cut thick branches?
Garden shears are not designed for thick branches. They work best on stems and twigs under 1 cm in diameter. Forcing shears through thicker wood damages the blades, bends the pivot mechanism, and gives you a crushed rather than clean cut. Crushed cuts heal slowly and leave the plant vulnerable to infection. For branches between 1 and 2 cm, use bypass pruning shears. For branches between 2 and 5 cm, use loppers. For anything thicker than 5 cm, use a pruning saw. Matching the tool to the stem size protects both the plant and the tool. If you try to cut a branch that feels too tough, stop immediately and switch to a stronger cutting tool. Replacing damaged shear blades costs nearly as much as buying a new pair, so respecting their limits saves money and produces better results.
