Does your garden soil need a boost? Plant green manure in your garden and you’ll improve your yields.

I recently found a partially finished bottle of an energy drink left behind in the euphorbia trough by one of the scaffolders. An architect friend 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 sprouting in the back corner.

This week, though, some necessary firefighting is underway. Being six months pregnant, I’ve hired a local gardener to remove troublesome weeds like a prickly weed and young tree shoots from the neighbour’s tree, but keeping desirable plants. Then, 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 previously discussed green manure, as they are essential in crop rotation for edible gardens. However, the only things I’m picking from my garden right now are a few foraged apples and some hardy herbs.

My garden goals are modest and consistent – and enhancing soil health is top of the list. For those wondering, 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 are like superheroes for your garden’s foundation. Bare soil invites weeds, which is why weeds appear. Yet by sowing vigorous crops, you can suppress weeds, attract pollinators, host pest-eating creatures, and fix nitrogen.

Cover crops aren’t always showy – though some, like lupins ‘Blue Sonet’ and a flowering legume, have lovely blooms – but their role is to thrive rather than be admired. After they’ve grown, you can dig them into the soil, cut them for compost, or let them decompose for worms to incorporate. The real magic happens underground.

Autumn is perfect for sowing these overwintering crops. I’ve chosen rye grass, great for clay soil, Italian ryegrass, a weed-suppressor, and field beans.

There’s satisfaction in sowing something that won’t stay forever – at least above ground.
