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

I recently found a half-empty bottle of Lucozade left behind in the euphorbia trough by one of the scaffolders. An architect friend joked, “Are you sure that’s Lucozade?” giving me a new perspective.

In short, the garden is in disarray. Sometimes neglect has its perks; coming back from a trip, I spotted a sunflower growing in the back corner.

This week, though, some necessary firefighting is underway. Being six months pregnant, I’ve hired a professional gardener to remove troublesome weeds like green alkanet and young tree shoots from the neighbour’s tree, but keeping desirable plants. Next, in the open patches, I’ll be sowing green manure.

Green manure are superheroes when it comes to boosting soil quality.

A fellow garden writer has written about green manure, as they play a key role in seasonal planting for edible gardens. But, the only things I’m harvesting from my garden right now are a few foraged apples and some hardy herbs.

My ambitions for the garden are modest and consistent – and enhancing soil health is my main priority. For those wondering, the scaffolding is for roof repairs, and the fences are still wobbly, but the neighbours are on board with the plan.

Green manure work wonders for your garden’s foundation. Bare soil invites weeds, which is why weeds appear. But by sowing fast-growing plants, you can suppress weeds, bring in bees, shelter beneficial insects, and fix nitrogen.

Green manure plants aren’t always showy – though some, like lupins ‘Blue Sonet’ and bird’s foot trefoil, have lovely blooms – but their purpose is to grow vigorously rather than look decorative. Once established, you can turn them under, chop them for mulch, or let them decompose for earthworms to pull down. Their work happens underground.

Now is the ideal time for sowing these overwintering crops. My selection includes rye grass, great for clay soil, a nitrogen-lifter, a weed-suppressor, and field beans.

There’s satisfaction in sowing something knowing it’s temporary – at least above ground.
