By the time the clocks go back, most British gardens have made up their minds about winter. Lawns turn to sponge, beds sulk, and the path you laid so carefully in June starts collecting whatever the wind throws at it. Pebble paths are tougher than most surfaces, but they are not self-maintaining. Leave the job until March and you will spend spring picking silt out of the gravel, scraping green film off the stones and wondering where half the surface went.
The work is not difficult, but the order matters. Get it done while the ground is still workable and the light is good enough to see what you are doing, and you will head into spring with a path that drains, sits flat and looks deliberate.
Clear Leaves Before They Turn to Silt
Fallen leaves are the biggest threat to a pebble path over winter. Dry, they blow about harmlessly. Wet, they mat into a soggy blanket that stops water reaching the drainage beneath and slowly rots into a fine, dark silt. That silt settles between the stones, fills the gaps and holds moisture against the surface — precisely the conditions moss and algae need to spread.
Keep on top of it rather than waiting for one big clear-up. Ten minutes with a leaf blower on its lowest setting, or a soft rubber rake, does more good than an hour of scraping at half-rotted sludge in January. On longer paths, work from one end and push everything ahead of you instead of sweeping in both directions.
- Empty leaves onto the compost heap or into a leaf bin — never onto the border, where they will simply blow back.
- Give corners, steps and the bottom of slopes a second pass; that is where leaves gather and stay damp.
- Conifer needles and birch catkins slip between pebbles, so a stiff broom works better than a rake.
- Check again after every named storm. An hour's work after a gale saves a weekend in February.
Check Drainage While You Can Still See It
A pebble path is only as good as the water it gets rid of. Once the autumn rain arrives, faults that were invisible in August show themselves quickly: puddles that sit for days, dark patches that never dry, gravel that feels soft underfoot.
Test the fall
On a dry afternoon, run a hose slowly across the highest point and watch where the water travels. It should move steadily towards a drain, a soakaway or a planting bed. If it stalls midway, the surface has settled or been compacted by foot traffic. Raking the pebbles level again, and topping up the low spots, often restores the flow.
Clear the outlets
Check any channel drain, gully or French drain at the end of the run and clear the silt, leaves and grit collected over summer. If a downpipe empties onto or beside the path, add a gully or a length of rigid pipe to carry water away from it. Water with nowhere to go will find the lowest point, which is usually the bit you walk on.
Reduce Moss and Algae Gently
Moss is a symptom, not the disease. It appears where light is poor, air is still and the surface stays damp. Shade from an overgrown shrub or a low branch will keep a path green no matter how often you scrape it, so start by pruning whatever is casting the shadow. Lift the skirts of shrubs, thin the canopy a little and let the wind reach the stones.
Then deal with what is already there. A stiff broom or a plastic-tined scarifying rake lifts moss from between the pebbles without shifting them. Work when the moss is dry and brittle; it comes away far more easily than the damp, clinging version.
Resist the urge to blast the path with a pressure washer at full power. It strips bedding sand, fires pebbles into the borders and can punch holes in the weed membrane underneath. If you do use a washer, keep it on a low setting, work on a dry day and be ready to re-level and top up afterwards. Proprietary path cleaners will kill moss and algae, but read the label and keep run-off away from ponds, borders and pets.
Check Edges, Liners and Loose Stones
Winter is hard on the details. Frost lifts and drops the ground repeatedly, and any weak point in the edging will open up. Walk the whole length and check:
- Edging boards, kerbs or setts that have shifted or begun to lean
- Weed membrane showing through where pebbles have worn thin
- Bare patches at gateways, steps and anywhere you turn on the spot
- Weeds pushing up along the edging, where roots loosen the structure
Firm or reset loose edging before the ground becomes too wet to work. Top up the pebbles so the membrane stays covered, but keep the layer shallow enough that it does not move constantly underfoot. Keep a bucket of matching pebbles in the shed: a five-minute repair in November beats rebuilding a corner in February.
Prepare for Frost and Ice
Loose pebbles freeze into a rough, shifting surface, and standing water on top of a path turns into a sheet of ice that catches everyone out. Before the first hard frost, clear any hollow that holds water and make sure leaves are not blocking the flow.
For gritting, sand or a salt-free de-icer is kinder than rock salt, which can damage planting and some types of edging over time. Scatter sparingly, and sweep off the worst of the slush once the thaw comes rather than letting it drain straight into the soil beside the path.
A Simple Seasonal Rhythm
- October: clear leaves weekly, prune back overhanging growth, rake the surface level.
- November: test drainage, clear gullies, reset loose edging, top up pebbles.
- December to February: sweep after storms, keep drains clear, grit carefully, repair bare patches as you spot them.
- Late February: check for frost damage, re-level hollows, and deal with the first flush of moss before spring growth takes hold.
Safety, and Knowing When to Call Someone In
Cold, wet work is the sort that causes injuries: lifting sodden bags of gravel, wrestling with a jammed pressure washer, running power tools on damp ground. Take the job in stages, keep loads sensible, and use an RCD on any outdoor socket. Wear gloves — pebbles, frost and slimy stone are a poor combination for bare hands.
If water still stands on the path once everything is cleared, or drains away only to return every time it rains, the problem is likely below the surface rather than on it. That is the moment to bring in a drainage or landscaping professional instead of digging hopefully at the edge of the gravel. A path that sheds water properly will shrug off most British winters. One that does not will keep reminding you about it until spring.
