Does your garden soil need a boost? Sow cover crops in your garden and you’ll enrich your soil.

Just the other day, I discovered a half-empty bottle of Lucozade placed in the euphorbia trough by one of the scaffolders. An architect friend joked, “Are you sure that’s Lucozade?” giving me a new perspective.

In short, the garden is in disarray. Sometimes neglect has its perks; after returning from holiday, I spotted a sunflower growing in the back corner.

This week, though, some urgent tidying is underway. Being six months pregnant, I’ve enlisted a professional gardener to tackle troublesome weeds like a prickly weed and young tree shoots from the neighbour’s tree, while leaving the good stuff. Then, in the open patches, I’ll be sowing cover crops.

Cover crops act like heroes when it comes to improving soil health.

My gardening friend Claire has written about cover crops, 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 foraged apples and some woody herbs.

My garden goals are modest and consistent – and enhancing soil health 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 replacing them.

Cover crops are like superheroes for soil health. Bare soil invites weeds, which is why weeds appear. But by sowing vigorous crops, you can control weeds, bring in bees, shelter beneficial insects, and fix nitrogen.

Cover crops 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 turn them under, cut them for compost, or let them decompose for worms to pull down. The real magic happens underground.

Now is the ideal time for sowing these overwintering crops. My selection includes rye grass, which breaks up heavy earth, Italian ryegrass, a weed-suppressor, and field beans.

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