Want to give your soil some TLC? Plant cover crops in your garden and you’ll reap the benefits.

Just the other day, I discovered a half-empty bottle of an energy drink left behind in the euphorbia trough by one of the scaffolders. A visiting architect joked, “Are you sure that’s Lucozade?” giving me a new perspective.

In short, the garden is a bit of a mess. But there’s a lot to be said for negligence; coming back from a trip, I spotted a sunflower sprouting in the back corner.

This week, though, some necessary firefighting is underway. Being six months pregnant, I’ve hired a local gardener to tackle troublesome weeds like green alkanet and robinia saplings from the neighbour’s tree, while leaving the good stuff. Then, in the newly cleared patches, I’ll be sowing cover crops.

Green manure are superheroes when it comes to improving soil health.

My gardening friend Claire has previously discussed cover crops, as they are essential in seasonal planting for edible gardens. But, the only things I’m picking from my garden right now are a few scrumped apples and some hardy herbs.

My garden goals are modest and consistent – and improving the soil is top of the list. To update concerned readers, the scaffolding is for roof repairs, and the garden boundaries are yet to be fixed, but the neighbours are on board with replacing them.

Cover crops work wonders for your garden’s foundation. Bare soil invites weeds, which is why weeds appear. Yet by sowing fast-growing plants, you can control weeds, bring in bees, host pest-eating creatures, and fix nitrogen.

Cover crops may not look exciting – though some, like lupins ‘Blue Sonet’ and a flowering legume, have lovely blooms – but their purpose is to grow vigorously rather than look decorative. Once established, you can turn them under, cut them for compost, or let them decompose for worms to pull down. Their work happens underground.

Now is the ideal time for sowing these cold-season plants. My selection includes forage rye, great for clay soil, a nitrogen-lifter, vetch, and beans that aerate soil.

There’s satisfaction in planting seeds that won’t stay forever – on the surface, anyway.
