Want to give your soil some TLC? Plant green manure in your garden and you’ll improve your yields.

I recently found a half-empty bottle of an energy drink placed in the euphorbia trough by one of the scaffolders. A visiting architect commented, “Are you sure that’s Lucozade?” giving me a new perspective.

All this is to say, the garden is a bit of a mess. 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 troublesome weeds like a prickly weed and young tree shoots from the neighbour’s tree, while leaving the good stuff. Next, in the newly cleared patches, I’ll be sowing cover crops.

Green manure are superheroes when it comes to improving soil health.

My gardening friend Claire has previously discussed cover crops, as they are essential in seasonal planting for vegetable plots. But, the only things I’m harvesting from my garden right now are a few foraged apples and some hardy herbs.

My ambitions for the garden are simple and steady – and improving the soil is my main priority. To update concerned readers, the scaffold is for roof repairs, and the fences are still wobbly, but the neighbours agree with replacing them.

Cover crops work wonders 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.

Green manure plants aren’t always showy – though some, like certain lupin varieties and bird’s foot trefoil, have lovely blooms – but their role is to thrive 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 worms to pull down. Their work happens underground.

Now is the ideal time for sowing these cold-season plants. I’ve chosen 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 – on the surface, anyway.
