Soil in need of some love? Plant green manure in your garden and you’ll enrich your soil.

Just the other day, I discovered a half-empty bottle of Lucozade placed in the euphorbia trough by one of the scaffolders. A visiting architect commented, “Are you sure that’s Lucozade?” which made me see it differently.

In short, the garden is a bit of a mess. 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. As I’m expecting a baby, I’ve enlisted a professional gardener to remove troublesome weeds like a prickly weed and robinia saplings from the neighbour’s tree, while leaving the good stuff. Next, in the open patches, I’ll be sowing green manure.

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

A fellow garden writer has previously discussed green manure, as they play a key role 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 ambitions for the garden are modest and consistent – and improving the soil 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.

Cover crops are like superheroes for soil health. Bare soil invites weeds, which is why unwanted plants pop up. But by sowing vigorous crops, you can control weeds, attract pollinators, shelter beneficial insects, and fix nitrogen.

Green manure plants aren’t always showy – though some, like certain lupin varieties and a flowering legume, have pretty flowers – but their purpose is to thrive rather than be admired. Once established, 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 cold-season plants. My selection includes rye grass, great for clay soil, Italian ryegrass, a weed-suppressor, and beans that aerate soil.

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