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

I recently found a half-empty bottle of Lucozade left behind in the euphorbia trough by one of the scaffolders. A visiting architect joked, “Are you sure that’s Lucozade?” giving me a new perspective.

All this is to say, 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 enlisted a local gardener to tackle troublesome weeds like green alkanet 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.

A fellow garden writer has written about green manure, as they are essential in crop rotation for edible gardens. But, 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 simple and steady – and enhancing soil health is my main priority. To update concerned readers, the scaffold is for roof repairs, and the garden boundaries are still wobbly, but the neighbours agree with the plan.

Cover crops work wonders for your garden’s foundation. Soil likes to be covered, which is why unwanted plants pop up. Yet by sowing vigorous crops, you can suppress weeds, attract pollinators, host pest-eating creatures, and fix nitrogen.

Cover crops may not look exciting – though some, like lupins ‘Blue Sonet’ and a flowering legume, have pretty flowers – but their role is to grow vigorously rather than be admired. Once established, you can dig them into the soil, chop them for mulch, or leave them on the surface for worms to incorporate. The real magic happens below the surface.

Autumn is perfect for sowing these cold-season plants. My selection includes rye grass, which breaks up heavy earth, a nitrogen-lifter, vetch, and field beans.

There’s satisfaction in sowing something that won’t stay forever – on the surface, anyway.
