Does your garden soil need a boost? Sow cover crops in your garden and you’ll reap the benefits.

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

All this is to say, 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 urgent tidying is underway. Being six months pregnant, I’ve enlisted a professional gardener to tackle troublesome weeds like green alkanet and young tree shoots from the neighbour’s tree, while leaving the good stuff. Next, in the open patches, I’ll be sowing cover crops.

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

A fellow garden writer has previously discussed green manure, 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 foraged apples and some hardy herbs.

My garden goals are modest and consistent – and improving the soil is top of the list. To update concerned readers, the scaffold is for roof repairs, and the garden boundaries are still wobbly, but the neighbours agree with the plan.

Green manure work wonders for soil health. Bare soil invites weeds, which is why weeds appear. Yet by sowing vigorous crops, you can control weeds, bring in bees, shelter beneficial insects, and enrich the soil with nutrients.

Green manure plants aren’t always showy – though some, like certain lupin varieties and a flowering legume, have pretty flowers – but their role 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 incorporate. The real magic happens underground.

Autumn is perfect for sowing these cold-season plants. My selection includes rye grass, great for clay soil, a nitrogen-lifter, a weed-suppressor, and beans that aerate soil.

It feels rewarding in sowing something knowing it’s temporary – at least above ground.
