Want to give your soil some TLC? Sow cover crops in your garden and you’ll reap the benefits.

I recently found a partially finished bottle of an energy drink left behind in the euphorbia trough by one of the scaffolders. An architect friend 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; coming back from a trip, I spotted a sunflower sprouting in the back corner.

This week, though, some urgent tidying is underway. Being six months pregnant, I’ve enlisted a professional gardener to remove invasive plants like a prickly weed and young tree shoots from the neighbour’s tree, while leaving the good stuff. Next, in the newly cleared patches, I’ll be sowing green manure.

Cover crops act like heroes when it comes to boosting soil quality.

My gardening friend Claire has previously discussed green manure, as they play a key role in seasonal planting for edible gardens. But, the only things I’m picking from my garden right now are a few scrumped apples and some hardy herbs.

My garden goals are simple and steady – and improving the soil is top of the list. To update concerned readers, the scaffold is for roof repairs, and the garden boundaries are still wobbly, but the neighbours agree with replacing them.

Green manure work wonders for soil health. Soil likes to be covered, which is why weeds appear. But by sowing fast-growing plants, you can suppress weeds, attract pollinators, shelter beneficial insects, and enrich the soil with nutrients.

Green manure plants aren’t always showy – though some, like certain lupin varieties and bird’s foot trefoil, have lovely blooms – but their purpose is to thrive rather than look decorative. Once established, you can turn them under, chop them for mulch, or let them decompose for earthworms to pull down. The real magic happens underground.

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

It feels rewarding in sowing something that won’t stay forever – on the surface, anyway.
