Soil in need of some love? Sow cover crops in your garden and you’ll reap the benefits.

I recently found a half-empty bottle of an energy drink placed 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 a bit of a mess. Sometimes neglect has its perks; 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 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. Then, in the newly cleared patches, I’ll be sowing cover crops.

Cover crops act like heroes when it comes to improving soil health.

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 harvesting from my garden right now are a few scrumped apples and some woody herbs.

My garden goals 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 yet to be fixed, but the neighbours agree with the plan.

Cover crops work wonders for soil health. Soil likes to be covered, which is why weeds appear. Yet by sowing fast-growing plants, you can suppress weeds, attract pollinators, 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 pretty flowers – 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 earthworms to pull down. Their work happens underground.

Autumn is perfect for sowing these overwintering crops. My selection includes rye grass, great for clay soil, a nitrogen-lifter, vetch, and field beans.

It feels rewarding in planting seeds knowing it’s temporary – at least above ground.
