Many gardeners are trying a simple, low-cost idea this winter: scattering old tennis balls around gardens. The practice is becoming popular because it is easy to do, reversible, and can reduce risks for small wildlife when done correctly.
Why gardeners are scattering tennis balls this winter
Gardeners are using tennis balls to reduce hazards that can trap or injure birds and hedgehogs. The bright, round shapes are visible, lightweight, and non-toxic, so they make a practical temporary tool in gardens.
This tactic is not a cure-all, but it can be useful in specific situations where small animals get caught in netting, gaps, or plastic containers during cold months.
How scattering tennis balls can help birds and hedgehogs
Tennis balls can be used as visual markers, gentle plugs, or soft stoppers. They help in three basic ways: visibility, blockage, and cushioning.
- Visibility: Bright balls highlight hazards like holes in bird netting, drainage covers, or mower detritus so people notice and remove risks.
- Blockage: A tennis ball can be used to block narrow gaps or pipe ends temporarily so animals cannot crawl into dangerous cavities.
- Cushioning: Placed around low garden edges or under fragile panels, balls can reduce sharp impacts for small mammals and birds.
Practical steps to scatter tennis balls safely
Follow simple safety steps when using tennis balls around wildlife. The aim is to reduce harm without creating new hazards or litter.
What you will need
- Used tennis balls (cleaned, no loose felt or foam)
- Scissors or a safe cutting tool if you need to modify balls
- Gloves and a bucket for collecting debris
- A notebook or phone to mark problem spots
Step-by-step guide
1. Survey your garden for hazards. Look for netting holes, open drains, uncovered compost bins, and garden furniture with gaps that a hedgehog or bird might enter.
2. Use tennis balls as temporary markers. Scatter them near hazards to draw attention during clean-up, or place a ball snugly in a narrow opening to block accidental entry.
3. Modify balls only when needed. If a ball must be fixed in place, cut a small slit and wedge it gently so it won’t fall into a drainage pipe or break into pieces.
4. Monitor and remove. Check marked areas daily and remove any balls once the hazard is fixed. Never leave balls where they could become micro-trash or be chewed by animals.
Where to place tennis balls and what to avoid
Place balls in visible locations, close to the hazard but not inside narrow cavities. Use them as temporary measures while you make permanent fixes, like patching netting or covering drains.
Avoid placing balls where animals might try to use them as bedding or food sources. Do not use balls inside burrows, tunnels, or small openings that wildlife may enter; this could trap or stress them.
- Good uses: marking net holes, blocking exposed pipe ends, cushioning sharp edges on garden furniture
- Bad uses: leaving balls inside compost piles, stuffing into burrows, or attaching with toxic adhesives
Hedgehogs can travel up to a mile a night when foraging in winter. Small obstacles or open containers in a garden can become trapping hazards if not noticed.
Materials and alternatives
Tennis balls are useful because they are common and soft, but there are alternatives. Small plastic cones, brightly colored garden markers, or capped drain covers can serve the same purpose without creating wear particles.
Always choose materials that are weather-resistant and easy to remove. Reuse old balls rather than buying new ones specifically for this task.
Tips for environmentally safe use
- Clean and inspect balls before use to remove loose fibers.
- Prefer natural or tightly bound materials to reduce shedding.
- Check local wildlife guidance if you are unsure whether a placement could disturb nesting birds or hibernating hedgehogs.
Small real-world example
Community gardener Clare in Sheffield noticed hedgehog tracks leading to a plastic drainage collar with a large gap. She placed three cleaned tennis balls around the collar and wrote a quick note about the hazard. Neighbors saw the markers, covered the collar, and fitted a small mesh over the drain within 48 hours.
The tennis balls acted as a quick, visible prompt that helped neighbors take action, and they were removed after the repair. Clare reports fewer tracks leading into the area afterward, and the hedgehogs were not disturbed.
When to ask for help
If you find an animal trapped, injured, or clearly in distress, contact a local wildlife rescue or vet immediately. Do not attempt complex rescues yourself unless you have training.
Local conservation groups can also advise on permanent fixes to garden hazards so you won’t need temporary markers in future winters.
Summary: practical, temporary, and careful
Scattering tennis balls this winter can be a helpful, temporary way to protect birds and hedgehogs by highlighting or blocking hazards. Use them thoughtfully, check placements often, and switch to permanent repairs as soon as possible.
When in doubt, consult local wildlife experts. Simple actions, combined with careful monitoring, can make gardens safer for small wildlife through the colder months.
