Want to give your soil some TLC? Sow cover crops in your garden and you’ll improve your yields.

I recently found a half-empty bottle of Lucozade placed 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.

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

This week, though, some necessary firefighting is underway. As I’m expecting a baby, I’ve hired a professional gardener to tackle troublesome weeds like green alkanet and robinia saplings from the neighbour’s tree, while leaving the good stuff. Next, in the newly cleared patches, I’ll be sowing cover crops.

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 vegetable plots. However, the only things I’m picking from my garden right now are a few scrumped apples and some woody herbs.

My garden goals are simple and steady – and improving the soil is top of the list. For those wondering, the scaffold is for roof repairs, and the garden boundaries are yet to be fixed, but the neighbours are on board with the plan.

Green manure work wonders for your garden’s foundation. Soil likes to be covered, which is why unwanted plants pop up. But by sowing fast-growing plants, you can suppress weeds, bring in bees, shelter beneficial insects, and fix nitrogen.

Green manure plants 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, cut them for compost, or leave them on the surface for worms to pull down. Their work happens underground.

Autumn is perfect for sowing these overwintering crops. My selection includes rye grass, which breaks up heavy earth, a nitrogen-lifter, vetch, and field beans.

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