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

Just the other day, I discovered a partially finished 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; after returning from holiday, I spotted a sunflower growing in the back corner.

Now, however, some urgent tidying is underway. As I’m expecting a baby, I’ve enlisted a professional gardener to tackle invasive plants like a prickly weed and young tree shoots from the neighbour’s tree, but keeping desirable plants. Then, in the newly cleared patches, I’ll be sowing green manure.

Green manure are superheroes when it comes to boosting soil quality.

A fellow garden writer has written about cover crops, as they are essential 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 ambitions for the garden are simple and steady – and improving the soil is top of the list. 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 are like superheroes for soil health. Bare soil invites weeds, which is why weeds appear. Yet by sowing fast-growing plants, you can suppress weeds, attract pollinators, shelter beneficial insects, and fix nitrogen.

Cover crops may not look exciting – though some, like certain lupin varieties and a flowering legume, have lovely blooms – but their purpose is to thrive rather than be admired. After they’ve grown, you can turn them under, chop them for mulch, or let them decompose for earthworms to pull down. Their work happens underground.

Autumn is perfect for sowing these cold-season plants. I’ve chosen forage rye, which breaks up heavy earth, a nitrogen-lifter, a weed-suppressor, and field beans.

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