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. A visiting architect 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; after returning from holiday, I spotted a sunflower sprouting in the back corner.

This week, though, some urgent tidying is underway. Being six months pregnant, I’ve hired a local gardener to tackle invasive plants like green alkanet 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.

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 crop rotation for edible gardens. However, the only things I’m harvesting 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. For those wondering, the scaffolding is for roof repairs, and the fences are still wobbly, but the neighbours are on board with the plan.

Cover crops are like superheroes for soil health. Soil likes to be covered, which is why weeds appear. Yet by sowing vigorous crops, you can control weeds, attract pollinators, shelter beneficial insects, and enrich the soil with nutrients.

Green manure plants may not look exciting – though some, like lupins ‘Blue Sonet’ and a flowering legume, have pretty flowers – but their role is to thrive rather than look decorative. After they’ve grown, you can dig them into the soil, chop them for mulch, or let them decompose for earthworms to incorporate. Their work happens below the surface.

Autumn is perfect for sowing these cold-season plants. I’ve chosen forage rye, which breaks up heavy earth, Italian ryegrass, vetch, and beans that aerate soil.

There’s satisfaction in sowing something knowing it’s temporary – at least above ground.
