Soil in need of some love? Sow cover crops in your garden and you’ll improve your yields.

I recently found a partially finished 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. Sometimes neglect has its perks; coming back from a trip, I spotted a sunflower sprouting in the back corner.

Now, however, some necessary firefighting is underway. Being six months pregnant, I’ve enlisted a professional gardener to remove troublesome weeds like a prickly weed and young tree shoots from the neighbour’s tree, while leaving the good stuff. Then, in the open patches, I’ll be sowing cover crops.

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 vegetable plots. But, the only things I’m picking from my garden right now are a few scrumped 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 replacing them.

Green manure are like superheroes for your garden’s foundation. Bare soil invites weeds, which is why unwanted plants pop up. But by sowing vigorous crops, you can suppress weeds, bring in bees, host pest-eating creatures, 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, cut them for compost, or let them decompose for earthworms to incorporate. Their work happens below the surface.

Autumn is perfect for sowing these cold-season plants. My selection includes forage rye, which breaks up heavy earth, Italian ryegrass, a weed-suppressor, and field beans.

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