Want to give your soil some TLC? Sow green manure in your garden and you’ll reap the benefits.

Just the other day, I discovered a half-empty bottle of an energy drink placed in the euphorbia trough by one of the scaffolders. A visiting architect commented, “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.

Now, however, some necessary firefighting is underway. Being six months pregnant, I’ve hired a professional gardener to remove 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 cover crops.

Green manure are superheroes when it comes to improving soil health.

A fellow garden writer has previously discussed green manure, as they play a key role in seasonal planting for edible gardens. But, 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 top of the list. For those wondering, the scaffold is for roof repairs, and the garden boundaries are still wobbly, but the neighbours agree with the plan.

Green manure are like superheroes for your garden’s foundation. Soil likes to be covered, which is why weeds appear. Yet by sowing vigorous crops, you can control weeds, bring in bees, host pest-eating creatures, and fix nitrogen.

Cover crops aren’t always showy – though some, like certain lupin varieties and bird’s foot trefoil, have pretty flowers – but their purpose 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 earthworms to pull down. The real magic happens below the surface.

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

There’s satisfaction in sowing something knowing it’s temporary – on the surface, anyway.
