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

I recently found a partially finished bottle of an energy drink placed in the euphorbia trough by one of the scaffolders. An architect friend commented, “Are you sure that’s Lucozade?” which made me see it differently.

In short, the garden is a bit of a mess. But there’s a lot to be said for negligence; coming back from a trip, I spotted a sunflower growing in the back corner.

This week, though, some necessary firefighting is underway. Being six months pregnant, I’ve hired a local gardener to remove troublesome weeds like green alkanet and young tree shoots from the neighbour’s tree, but keeping desirable plants. Next, in the open patches, I’ll be sowing cover crops.

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

A fellow garden writer has written about cover crops, as they play a key role in crop rotation for edible gardens. However, the only things I’m harvesting 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 top of the list. For those wondering, the scaffold is for roof repairs, and the garden boundaries are still wobbly, but the neighbours agree with replacing them.

Green manure work wonders for soil health. Bare soil invites weeds, which is why weeds appear. But by sowing vigorous crops, you can suppress weeds, bring in bees, shelter beneficial insects, and fix nitrogen.

Green manure plants may not look exciting – though some, like certain lupin varieties and a flowering legume, have lovely blooms – but their purpose is to grow vigorously rather than be admired. Once established, you can dig them into the soil, cut them for compost, or leave them on the surface for earthworms to pull down. The real magic happens underground.

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

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