Does your garden soil need a boost? Plant green manure in your garden and you’ll reap the benefits.

Just the other day, I discovered a partially finished bottle of Lucozade left behind 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 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 local gardener to tackle invasive plants like a prickly weed 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.

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

A fellow garden writer has previously discussed cover crops, as they play a key role in crop rotation for vegetable plots. But, the only things I’m harvesting from my garden right now are a few scrumped apples and some hardy 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 fences are still wobbly, but the neighbours are on board with replacing them.

Cover crops work wonders for your garden’s foundation. Bare soil invites weeds, which is why weeds appear. But by sowing vigorous crops, you can suppress weeds, attract pollinators, host pest-eating creatures, and enrich the soil with nutrients.

Green manure plants may not look exciting – though some, like lupins ‘Blue Sonet’ and bird’s foot trefoil, have lovely blooms – but their role is to thrive rather than be admired. After they’ve grown, you can turn them under, cut them for compost, or leave them on the surface for worms to pull down. The real magic happens underground.

Autumn is perfect for sowing these overwintering crops. I’ve chosen forage rye, which breaks up heavy earth, a nitrogen-lifter, a weed-suppressor, and beans that aerate soil.

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