Want to give your soil some TLC? Sow green manure in your garden and you’ll improve your yields.

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

All this is to say, the garden is a bit of a mess. But there’s a lot to be said for negligence; after returning from holiday, I spotted a sunflower sprouting in the back corner.

This week, though, some urgent tidying is underway. As I’m expecting a baby, I’ve enlisted a professional gardener to remove invasive plants like a prickly weed and young tree shoots from the neighbour’s tree, but keeping desirable plants. Next, 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 crop rotation for edible gardens. However, the only things I’m harvesting from my garden right now are a few foraged apples and some hardy herbs.

My ambitions for the garden are simple and steady – and improving the soil is my main priority. For those wondering, the scaffold is for roof repairs, and the fences are still wobbly, but the neighbours agree with the plan.

Green manure work wonders for your garden’s foundation. Soil likes to be covered, which is why unwanted plants pop up. Yet by sowing fast-growing plants, you can suppress weeds, bring in bees, shelter beneficial insects, and fix nitrogen.

Green manure plants aren’t always showy – though some, like certain lupin varieties and a flowering legume, have lovely blooms – but their role is to thrive rather than look decorative. After they’ve grown, you can turn them under, cut them for compost, or leave them on the surface for earthworms to pull down. The real magic happens below the surface.

Now is the ideal time for sowing these overwintering crops. My selection includes rye grass, which breaks up heavy earth, Italian ryegrass, a weed-suppressor, and beans that aerate soil.

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