Want to give your soil some TLC? 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. An architect friend commented, “Are you sure that’s Lucozade?” giving me a new perspective.

In short, 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 urgent tidying is underway. Being six months pregnant, I’ve enlisted a local gardener to tackle troublesome weeds like green alkanet and young tree shoots from the neighbour’s tree, but keeping desirable plants. Then, in the open patches, I’ll be sowing green manure.

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

My gardening friend Claire has written about green manure, as they play a key role in seasonal planting for edible gardens. However, the only things I’m harvesting from my garden right now are a few foraged apples and some woody herbs.

My ambitions for the garden 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 are on board with replacing them.

Cover crops work wonders for soil health. Bare soil invites weeds, which is why unwanted plants pop up. But by sowing vigorous crops, you can control weeds, bring in bees, host pest-eating creatures, and fix nitrogen.

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, chop them for mulch, or leave them on the surface for earthworms to incorporate. The real magic happens underground.

Autumn is perfect for sowing these overwintering crops. My selection includes rye grass, which breaks up heavy earth, a nitrogen-lifter, a weed-suppressor, and beans that aerate soil.

It feels rewarding in sowing something that won’t stay forever – at least above ground.
