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

I recently found 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.

In short, the garden is in disarray. Sometimes neglect has its perks; coming back from a trip, I spotted a sunflower growing in the back corner.

This week, though, some necessary firefighting is underway. As I’m expecting a baby, I’ve hired a local gardener to remove invasive plants like a prickly weed and robinia saplings from the neighbour’s tree, but keeping desirable plants. Next, in the newly cleared patches, I’ll be sowing cover crops.

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

My gardening friend Claire has previously discussed green manure, as they are essential in crop rotation for edible gardens. However, the only things I’m picking from my garden right now are a few foraged apples and some woody herbs.

My garden goals are simple and steady – and enhancing soil health is my main priority. To update concerned readers, the scaffold is for roof repairs, and the garden boundaries are yet to be fixed, but the neighbours agree with replacing them.

Cover crops are like superheroes for soil health. Bare soil invites weeds, which is why weeds appear. Yet by sowing fast-growing plants, you can control weeds, attract pollinators, shelter beneficial insects, and fix nitrogen.

Cover crops may not look exciting – though some, like certain lupin varieties and bird’s foot trefoil, have pretty flowers – but their role is to grow vigorously 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 pull down. Their work happens underground.

Autumn is perfect for sowing these cold-season plants. I’ve chosen rye grass, great for clay soil, a nitrogen-lifter, vetch, and field beans.

It feels rewarding in sowing something that won’t stay forever – at least above ground.
