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

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

All this is to say, the garden is a bit of a mess. Sometimes neglect has its perks; coming back from a trip, I spotted a sunflower growing in the back corner.

This week, though, some necessary firefighting is underway. As I’m expecting a baby, I’ve enlisted a local gardener to tackle invasive plants like a prickly weed and robinia saplings from the neighbour’s tree, but keeping desirable plants. Next, in the open patches, I’ll be sowing green manure.

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

A fellow garden writer has written about green manure, as they play a key role in crop rotation 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 ambitions for the garden are simple and steady – and improving the soil is top of the list. For those wondering, the scaffold is for roof repairs, and the fences are still wobbly, but the neighbours agree with replacing them.

Green manure work wonders for your garden’s foundation. Bare soil invites weeds, which is why unwanted plants pop up. Yet by sowing fast-growing plants, you can control weeds, attract pollinators, host pest-eating creatures, and enrich the soil with nutrients.

Cover crops aren’t always showy – though some, like lupins ‘Blue Sonet’ and a flowering legume, have lovely blooms – but their role is to grow vigorously rather than be admired. After they’ve grown, you can dig them into the soil, chop them for mulch, or leave them on the surface for worms to incorporate. The real magic happens underground.

Autumn is perfect for sowing these overwintering crops. My selection includes rye grass, great for clay soil, a nitrogen-lifter, a weed-suppressor, and field beans.

It feels rewarding in planting seeds knowing it’s temporary – on the surface, anyway.
