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?” 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 growing in the back corner.

Now, however, some urgent tidying is underway. Being six months pregnant, I’ve hired a local gardener to tackle invasive plants like green alkanet and young tree shoots from the neighbour’s tree, but keeping desirable plants. Then, in the open patches, I’ll be sowing cover crops.

Green manure are superheroes when it comes to boosting soil quality.

My gardening friend Claire has written about cover crops, as they are essential in crop rotation for vegetable plots. However, the only things I’m picking from my garden right now are a few foraged apples and some woody herbs.

My ambitions for the garden are modest and consistent – and enhancing soil health is top of the list. To update concerned readers, the scaffold is for roof repairs, and the fences are yet to be fixed, but the neighbours are on board with the plan.

Green manure work wonders for soil health. Bare soil invites weeds, which is why weeds appear. Yet by sowing fast-growing plants, you can suppress weeds, attract pollinators, host pest-eating creatures, and enrich the soil with nutrients.

Green manure plants 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 be admired. Once established, you can turn them under, chop them for mulch, or leave them on the surface for worms to incorporate. Their work happens underground.

Autumn is perfect for sowing these cold-season plants. My selection includes forage rye, great for clay soil, Italian ryegrass, vetch, and beans that aerate soil.

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