Does your garden soil need a boost? Sow 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 commented, “Are you sure that’s Lucozade?” giving me a new perspective.

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

This week, though, some necessary firefighting is underway. As I’m expecting a baby, I’ve enlisted a professional gardener to remove 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 boosting soil quality.

My gardening friend Claire has written about green manure, as they are essential in crop rotation for edible gardens. However, the only things I’m harvesting from my garden right now are a few foraged apples and some woody herbs.

My ambitions for the garden are simple and steady – and enhancing soil health is my main priority. For those wondering, the scaffold is for roof repairs, and the garden boundaries are still wobbly, but the neighbours are on board with replacing them.

Cover crops are like superheroes for soil health. Bare soil invites weeds, which is why weeds appear. But by sowing vigorous crops, you can control weeds, attract pollinators, host pest-eating creatures, and fix nitrogen.

Cover crops aren’t always showy – though some, like lupins ‘Blue Sonet’ and bird’s foot trefoil, have pretty flowers – but their purpose is to thrive rather than be admired. After they’ve grown, you can turn them under, cut them for compost, or leave them on the surface for worms to incorporate. Their work happens underground.

Now is the ideal time for sowing these cold-season plants. My selection includes rye grass, great for clay soil, Italian ryegrass, a weed-suppressor, and beans that aerate soil.

It feels rewarding in sowing something knowing it’s temporary – on the surface, anyway.
