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 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. Sometimes neglect has its perks; after returning from holiday, I spotted a sunflower sprouting in the back corner.

Now, however, some necessary firefighting is underway. Being six months pregnant, I’ve hired a local gardener to remove invasive plants like a prickly weed and robinia saplings from the neighbour’s tree, while leaving the good stuff. Then, in the open patches, I’ll be sowing green manure.

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

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

My garden goals are simple and steady – and improving the soil is top of the list. To update concerned readers, the scaffolding is for roof repairs, and the garden boundaries are still wobbly, but the neighbours are on board with the plan.

Green manure are like superheroes for your garden’s foundation. Soil likes to be covered, which is why unwanted plants pop up. Yet by sowing vigorous crops, you can control weeds, attract pollinators, shelter beneficial insects, and fix nitrogen.

Green manure plants may not look exciting – though some, like lupins ‘Blue Sonet’ and a flowering legume, have lovely blooms – but their purpose 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 earthworms to pull down. Their work happens below the surface.

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

It feels rewarding in sowing something knowing it’s temporary – at least above ground.
