Soil in need of some love? Plant green manure in your garden and you’ll reap the benefits.

Just the other day, I discovered a half-empty bottle of an energy drink placed in the euphorbia trough by one of the scaffolders. A visiting architect joked, “Are you sure that’s Lucozade?” which made me see it differently.

All this is to say, the garden is in disarray. 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 urgent tidying is underway. As I’m expecting a baby, I’ve hired a professional gardener to tackle invasive plants like a prickly weed and robinia saplings from the neighbour’s tree, while leaving the good stuff. Next, in the open patches, I’ll be sowing cover crops.

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

A fellow garden writer has written about cover crops, as they are essential in seasonal planting for edible gardens. However, the only things I’m picking from my garden right now are a few scrumped apples and some woody herbs.

My ambitions for the garden are simple and steady – and improving the soil is my main priority. To update concerned readers, the scaffolding is for roof repairs, and the fences are still wobbly, but the neighbours agree with the plan.

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 suppress weeds, bring in bees, shelter beneficial insects, and fix nitrogen.

Cover crops aren’t always showy – though some, like lupins ‘Blue Sonet’ and a flowering legume, have pretty flowers – but their role is to thrive rather than be admired. Once established, you can turn them under, cut them for compost, or leave them on the surface for worms to incorporate. Their work happens below the surface.

Now is the ideal time for sowing these overwintering crops. I’ve chosen forage rye, great for clay soil, a nitrogen-lifter, a weed-suppressor, and beans that aerate soil.

It feels rewarding in sowing something that won’t stay forever – at least above ground.
