The problem with a fence that is hemmed in
When a garden is only a few steps wide, the beds, paths and lawn all end at the fence. Over a season, soil creeps up the boards, mulch gets heaped against them and leaves settle in the corners. Each of these holds water against the timber and cuts off the air it needs to dry out. Narrow gardens also mean there is less room to work, so a short handled brush and a small trowel are the most useful tools.
The damage is slow and easy to miss, because the boards still look fine from above. By the time a bottom board feels soft, the rot is often in the rail and post behind it. Checking the foot of the fence a couple of times a year catches this early, while a simple fix still works. A plastic or gravel strip beside the fence can stop the soil spilling onto the base.
Beds, planters and climbers
If you grow in a border against the fence, think about how it is built. Soil piled to the full height of a board is the same as burying that board. Where you can, keep soil below the bottom edge of the lowest board, and consider a gravel board or a raised edge that holds the soil back instead. Because everything is close together, protect plants and paving from drips and splashes before you treat the wood.
Planters and pots are better moved a hand's width from the timber so air moves behind them. For climbers, a trellis or a few wires fixed on short spacers lets the plant grow while keeping its stems and wet leaves off the wood. Prune back anything that is pushing between boards or lifting a panel. Where fences are shared between several houses along a street, repairs on one length can affect the next, which is another reason to talk to neighbours early.
A quick tidy that makes a difference
Once a season, pull everything away from the base, brush the boards down and look for any green slime, soft patches or fungus. A dry brush clears the surface, and a damp cloth does the rest. Let the timber dry, then apply preservative to any bare patches in dry weather. If you have a raised bed against the fence, a liner between the soil and the boards will help keep the wood drier.
Check the shared sides of the fence with your neighbour in mind. If a panel on the boundary needs work, it is wise to have a friendly word before anything is changed. For questions about who owns or looks after a particular fence, check your deeds or ask the local council, as this is general information only. It is general information only, so check your deeds or ask the council if you are unsure about a boundary.
Quick tips
- Keep soil and mulch below the bottom board, and use a gravel board or edging to hold it back.
- Move pots, bins and stored items a hand's width from the fence so air can circulate behind them.
- Fix trellis or wires to the fence on short spacers so climbers do not press stems against the wood.
- Treat bare or cut timber in dry weather and wait for it to dry fully before putting anything back.

Frequently asked questions
Why is soil against the bottom of my fence a problem?
Soil piled to the full height of a board is the same as burying that board. It holds water against the timber and cuts off the air it needs to dry. In narrow Sparkhill gardens, keep soil below the lowest board, or use a gravel board or liner.
How can I grow climbers without harming the fence boards?
Fix a trellis or a few wires on short spacers so the plant grows while its stems and wet leaves stay off the wood. Prune back anything pushing between boards or lifting a panel. In tight Sparkhill gardens, also move pots a hand's width away.
