Want to give your soil some TLC? Sow green manure in your garden and you’ll reap the benefits.

I recently found a half-empty bottle of Lucozade left behind in the euphorbia trough by one of the scaffolders. An architect friend commented, “Are you sure that’s Lucozade?” giving me a new perspective.

All this is to say, the garden is in disarray. But there’s a lot to be said for negligence; after returning from holiday, I spotted a sunflower sprouting in the back corner.

Now, however, some urgent tidying 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 newly cleared patches, I’ll be sowing cover crops.

Cover crops act like heroes when it comes to boosting soil quality.

A fellow garden writer has written about green manure, as they play a key role in seasonal planting 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 modest and consistent – and enhancing soil health is top of the list. To update concerned readers, the scaffold is for roof repairs, and the fences are still wobbly, but the neighbours are on board with replacing them.

Green manure work wonders for soil health. Soil likes to be covered, which is why unwanted plants pop up. But by sowing vigorous crops, you can control weeds, bring in bees, shelter beneficial insects, and enrich the soil with nutrients.

Green manure plants may not look exciting – though some, like certain lupin varieties and bird’s foot trefoil, have pretty flowers – but their role is to thrive rather than look decorative. Once established, you can turn them under, cut them for compost, or leave them on the surface for earthworms to incorporate. The real magic happens below the surface.

Autumn is perfect for sowing these overwintering crops. My selection includes rye grass, which breaks up heavy earth, a nitrogen-lifter, vetch, and beans that aerate soil.

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