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

Just the other day, I discovered a half-empty bottle of Lucozade placed in the euphorbia trough by one of the scaffolders. A visiting architect joked, “Are you sure that’s Lucozade?” which made me see it differently.

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 necessary firefighting is underway. Being six months pregnant, I’ve hired a professional gardener to remove troublesome weeds like a prickly weed and young tree shoots from the neighbour’s tree, while leaving the good stuff. Next, in the open patches, I’ll be sowing cover crops.

Green manure are superheroes 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 scrumped apples and some hardy herbs.

My ambitions for the garden 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 garden boundaries are still wobbly, but the neighbours are on board with replacing them.

Cover crops are like superheroes for your garden’s foundation. Soil likes to be covered, which is why weeds appear. But by sowing vigorous crops, you can suppress weeds, attract pollinators, host pest-eating creatures, and fix nitrogen.

Cover crops aren’t always showy – though some, like certain lupin varieties and a flowering legume, have lovely blooms – 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 leave them on the surface for worms to pull down. The real magic happens underground.

Now is the ideal time for sowing these overwintering crops. I’ve chosen rye grass, great for clay soil, Italian ryegrass, a weed-suppressor, and beans that aerate soil.

There’s satisfaction in planting seeds knowing it’s temporary – on the surface, anyway.
