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

I recently found a partially finished bottle of an energy drink placed 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. But there’s a lot to be said for negligence; coming back from a trip, I spotted a sunflower growing in the back corner.

This week, though, some urgent tidying is underway. As I’m expecting a baby, I’ve enlisted a professional gardener to remove troublesome weeds like a prickly weed and young tree shoots from the neighbour’s tree, while leaving the good stuff. Then, in the open patches, I’ll be sowing green manure.

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

A fellow garden writer has written about green manure, as they are essential in crop rotation for vegetable plots. But, the only things I’m picking from my garden right now are a few scrumped apples and some hardy herbs.

My garden goals are modest and consistent – and improving the soil is top of the list. To update concerned readers, the scaffold is for roof repairs, and the fences are yet to be fixed, but the neighbours agree with the plan.

Cover crops are like superheroes for your garden’s foundation. Bare soil invites weeds, which is why weeds appear. But by sowing vigorous crops, you can suppress weeds, bring in bees, host pest-eating creatures, and enrich the soil with nutrients.

Cover crops may not look exciting – though some, like lupins ‘Blue Sonet’ and a flowering legume, have pretty flowers – but their purpose is to thrive rather than be admired. Once established, you can turn them under, cut them for compost, or leave them on the surface for earthworms to incorporate. The real magic happens below the surface.

Now is the ideal time for sowing these cold-season plants. My selection includes rye grass, which breaks up heavy earth, a nitrogen-lifter, vetch, and beans that aerate soil.

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