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

I recently found a half-empty bottle of Lucozade left behind 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. But there’s a lot to be said for negligence; coming back from a trip, I spotted a sunflower sprouting in the back corner.

Now, however, some urgent tidying is underway. Being six months pregnant, I’ve enlisted a professional gardener to remove invasive plants 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 cover crops.

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. However, the only things I’m harvesting from my garden right now are a few foraged apples and some woody herbs.

My ambitions for the garden are simple and steady – and improving the soil is my main priority. To update concerned readers, the scaffolding is for roof repairs, and the garden boundaries are still wobbly, but the neighbours agree with the plan.

Cover crops work wonders for soil health. Soil likes to be covered, which is why weeds appear. But by sowing vigorous crops, you can control weeds, attract pollinators, host pest-eating creatures, and fix nitrogen.

Cover crops aren’t always showy – though some, like lupins ‘Blue Sonet’ and a flowering legume, have pretty flowers – but their role is to grow vigorously rather than look decorative. After they’ve grown, you can turn them under, chop them for mulch, or let them decompose for earthworms to incorporate. The real magic happens underground.

Now is the ideal time for sowing these cold-season plants. I’ve chosen forage rye, great for clay soil, a nitrogen-lifter, vetch, and field beans.

It feels rewarding in sowing something knowing it’s temporary – at least above ground.
