Soil in need of some love? Sow green manure in your garden and you’ll improve your yields.

Just the other day, I discovered a partially finished bottle of an energy drink placed in the euphorbia trough by one of the scaffolders. A visiting architect joked, “Are you sure that’s Lucozade?” which made me see it differently.

All this is to say, the garden is a bit of a mess. Sometimes neglect has its perks; coming back from a trip, I spotted a sunflower sprouting in the back corner.

Now, however, some necessary firefighting is underway. As I’m expecting a baby, I’ve hired a professional gardener to remove troublesome weeds like green alkanet 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 boosting soil quality.

A fellow garden writer has written about cover crops, as they play a key role in seasonal planting for vegetable plots. However, the only things I’m harvesting from my garden right now are a few foraged apples and some hardy herbs.

My garden goals are simple and steady – and improving the soil is my main priority. For those wondering, the scaffold is for roof repairs, and the fences are yet to be fixed, but the neighbours agree with replacing them.

Green manure are like superheroes for soil health. Soil likes to be covered, which is why unwanted plants pop up. But by sowing fast-growing plants, you can control weeds, bring in bees, shelter beneficial insects, and fix nitrogen.

Cover crops aren’t always showy – though some, like lupins ‘Blue Sonet’ and bird’s foot trefoil, have lovely blooms – but their purpose is to grow vigorously rather than be admired. After they’ve grown, you can dig them into the soil, cut them for compost, or leave them on the surface for earthworms to incorporate. Their work happens below the surface.

Autumn is perfect for sowing these cold-season plants. My selection includes forage rye, which breaks up heavy earth, Italian ryegrass, a weed-suppressor, and beans that aerate soil.

It feels rewarding in planting seeds that won’t stay forever – on the surface, anyway.
