If you consider yourself a budding horticulturist or generally just like to keep your garden in tip-top shape, then it's likely you've acquired an extensive range of gardening tools over the years. But chances are, you've not got enough space to store them.

It happens to the best of us — we don't think before we buy. Which is why now's the perfect time to think about investing in a garden storage box to house all your green fingered bits and bobs.

Sturdy outdoor storage comes in various shapes, colours, materials and sizes, and is ideal if your garage or shed is full to the brim or you're simply short on storage space.

Not only compact and easy on the eye, they're often super affordable and (sometimes) even double up as garden furniture.

Stumped for choice? Fear not, as we've compiled a list of the top-rated designs to suit everyone’s needs and budgets. Here's the best garden storage units, ranging in price from as little as £28 to £185.
