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

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

All this is to say, the garden is in disarray. 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. Being six months pregnant, I’ve hired a professional gardener to tackle troublesome weeds like a prickly weed and robinia saplings from the neighbour’s tree, while leaving the good stuff. Next, in the newly cleared patches, I’ll be sowing green manure.

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

A fellow garden writer has previously discussed cover crops, as they play a key role in crop rotation for edible gardens. 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 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 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. Yet by sowing fast-growing plants, you can suppress weeds, attract pollinators, host pest-eating creatures, and fix nitrogen.

Green manure plants aren’t always showy – though some, like lupins ‘Blue Sonet’ and a flowering legume, have pretty flowers – but their purpose is to thrive rather than look decorative. Once established, you can dig them into the soil, cut them for compost, or let them decompose for earthworms to pull down. The real magic happens below the surface.

Autumn is perfect for sowing these overwintering crops. I’ve chosen forage rye, great for clay soil, a nitrogen-lifter, a weed-suppressor, and beans that aerate soil.

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