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 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.

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 growing in the back corner.

Now, however, some necessary firefighting is underway. As I’m expecting a baby, I’ve enlisted a professional gardener to remove invasive plants like a prickly weed and robinia saplings from the neighbour’s tree, while leaving the good stuff. Then, in the open patches, I’ll be sowing green manure.

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

My gardening friend Claire has previously discussed cover crops, as they are essential in seasonal planting for edible gardens. However, the only things I’m picking from my garden right now are a few scrumped apples and some woody herbs.

My garden goals 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 still wobbly, but the neighbours agree with the plan.

Green manure work wonders for soil health. Soil likes to be covered, which is why weeds appear. But by sowing vigorous crops, you can suppress 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 look decorative. After they’ve grown, you can turn them under, cut them for compost, or leave them on the surface for worms to pull down. The real magic happens underground.

Now is the ideal time for sowing these overwintering crops. I’ve chosen forage rye, great for clay soil, Italian ryegrass, a weed-suppressor, and field beans.

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