Want to give your soil some TLC? Plant green manure in your garden and you’ll enrich your soil.

Just the other day, I discovered a partially finished bottle of Lucozade placed 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 a bit of a mess. Sometimes neglect has its perks; after returning from holiday, I spotted a sunflower growing in the back corner.

This week, though, some urgent tidying is underway. Being six months pregnant, I’ve hired a local gardener to tackle troublesome weeds like a prickly weed and robinia saplings from the neighbour’s tree, but keeping desirable plants. Then, in the newly cleared patches, I’ll be sowing cover crops.

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

A fellow garden writer has written about green manure, as they play a key role in seasonal planting for vegetable plots. However, the only things I’m picking from my garden right now are a few scrumped apples and some woody herbs.

My garden goals are modest and consistent – and improving the soil is my main priority. For those wondering, the scaffold is for roof repairs, and the garden boundaries are still wobbly, but the neighbours agree with the plan.

Green manure are like superheroes for your garden’s foundation. Bare soil invites weeds, which is why weeds appear. But by sowing vigorous crops, you can suppress weeds, attract pollinators, shelter beneficial insects, and fix nitrogen.

Green manure plants aren’t always showy – though some, like certain lupin varieties and bird’s foot trefoil, have pretty flowers – but their purpose is to thrive rather than look decorative. Once established, you can turn them under, cut them for compost, or leave them on the surface for earthworms to pull down. Their work happens below the surface.

Autumn is perfect for sowing these cold-season plants. My selection includes rye grass, great for clay soil, Italian ryegrass, a weed-suppressor, and field beans.

There’s satisfaction in sowing something knowing it’s temporary – on the surface, anyway.
