Keeping Allotment Paths Clear and Safe

Why Clear Paths Are the Making of a Plot

Every allotment holder knows the feeling. You have spent a satisfying morning weeding the beds, then the heavens open and the next three weeks are spent tiptoeing round the mud, balancing a fork in one hand and hoping your boots come back out of the clay. The beds were never the problem. The paths were.

Paths are the skeleton of a plot. Giving a quarter of your ground over to them is not waste; it is what makes the other three quarters workable. Good paths let you push a barrow of well-rotted manure to the far bed in February, reach a row of brassicas without compacting the soil beside them, and stay upright while carrying a full watering can. They also set the tone. A plot with clean, defined lines feels cared for even in the depths of winter, and it is far easier to spot the weeds that need dealing with.

Work Out the Layout Before You Buy Anything

Pace the plot out first, and be honest about how you actually move around it. Most people overestimate how much growing space they need and underestimate how much walking they do. A little time with a tape measure and some canes will save a great deal of lifting and cursing later.

• Main path: allow 90cm to 1.2m. A loaded wheelbarrow needs roughly 70cm of clear width, plus a bit of room for your knuckles.
• Bed-side paths: 45cm to 60cm is plenty, just enough to kneel, weed and reach across a bed without stepping on it.
• Corners: a tight right angle is where barrows get stuck. Sweep the turn slightly, or widen the junction by a slab's width.
• Slope: water runs downhill whether you plan for it or not. Let paths fall gently towards a drain or a soakaway at the lowest corner rather than pooling outside the shed door.

If your site has rules about permanent structures, check them before you start digging a sub-base. On many allotments, slabs and edging count as permanent; bark chips and membrane generally do not.

Bark Chips: Cheap, Quick and Kind Underfoot

For most plots, bark chips are the sensible starting point. Spread them 50mm to 75mm deep over a woven membrane and you have an instant, soft path that suppresses weeds, drains well and takes a barrow without rutting. If you can get hold of woodchip from a local tree surgeon, so much the better — it is usually free, and a coarse, chunky chip lasts far longer than the fine ornamental bark sold for borders.

Do be aware of the drawbacks. Chips break down over time and need topping up every year or two, which is a job best done in spring when the ground is warming up. Fresh woodchip can also rob nitrogen from the soil at the edges if it is dug in, so keep it on the path where it belongs. On a slope, and especially once the chips have rotted to a mush, they can become genuinely slippery — consider slabs or gravel there instead.

Paving Slabs and the Permanent Spine

If you only invest in one hard surface, make it the main path. Concrete slabs at 600 x 600mm, or the larger 900 x 600mm, will outlast your tenancy and can often be picked up second-hand from a builder's yard or a neighbour's skip. Lay them on a bed of sharp sand over a compacted sub-base of MOT Type 1, firming each slab down with a rubber mallet and checking for level as you go. Aim for the surface to sit just proud of the soil, with a very slight fall for drainage.

Slabs give you a firm, dry route in all weathers and a clean edge to mow or strim against. Their one weakness is moss and algae, which turn a smooth surface into an ice rink by November. An annual scrub with a stiff broom and a bucket of sharp sand, plus a little extra attention to shaded stretches, keeps them safe. Avoid polished or glazed stone; a lightly textured riven or brushed finish is far more forgiving.

Woven Membrane: The Hidden Workhorse

Underneath everything, a good woven geotextile does the quiet work. Woven fabric has a much higher tear strength than the non-woven fleece sold for mulching, and it resists the punctures that come from kneeling, forks and stray stones. Overlap the edges by 100mm to 150mm and pin them down well, turning the fabric up at the sides of the bed to stop soil spilling across.

Lay it under bark chips, and under the sand bedding for slabs. Be realistic about what it can do: it stops annual weeds germinating, but couch grass and bindweed will happily creep through a tear or over the top, so keep the edges tidy. It also degrades in sunlight, so it needs to stay covered.

Keeping Paths Clear Through the Year

A path is only as good as its maintenance. A few minutes each week keeps the whole plot safer and more pleasant to work in.

• Brush fallen leaves off slabs in autumn — wet leaves are as treacherous as ice.
• Re-cut the edges of bark paths with a half-moon edger in spring, before grass and weeds creep in.
• Top up chips little and often rather than in one thick dump, which smothers the membrane and holds water.
• Clear any debris from the base of a slope so winter rain has somewhere to go.
• Inspect the whole route in the wet, in wellies, with a barrow. Anything that makes you slow down is a job for next weekend.

Get the paths right and everything else on the plot becomes easier — more time growing, less time sliding about in the mud.
