Does your garden soil need a boost? Plant cover crops in your garden and you’ll improve your yields.

I recently found a half-empty bottle of Lucozade left behind 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 in disarray. 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 necessary firefighting 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 newly cleared patches, I’ll be sowing cover crops.

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

My gardening friend Claire has previously discussed cover crops, as they play a key role in seasonal planting for vegetable plots. But, the only things I’m picking from my garden right now are a few foraged apples and some hardy herbs.

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

Green manure are like superheroes for soil health. Soil likes to be covered, which is why unwanted plants pop up. Yet by sowing fast-growing plants, you can control weeds, attract pollinators, host pest-eating creatures, and fix nitrogen.

Green manure plants aren’t always showy – though some, like lupins ‘Blue Sonet’ and bird’s foot trefoil, have lovely blooms – but their role is to grow vigorously rather than be admired. Once established, you can dig them into the soil, cut them for compost, or leave them on the surface for worms to incorporate. Their work happens below the surface.

Now is the ideal time for sowing these cold-season plants. My selection includes rye grass, great for clay soil, a nitrogen-lifter, a weed-suppressor, and beans that aerate soil.

It feels rewarding in sowing something that won’t stay forever – at least above ground.
