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

I recently found a half-empty bottle of Lucozade 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 in disarray. Sometimes neglect has its perks; after returning from holiday, I spotted a sunflower growing in the back corner.

This week, though, some urgent tidying is underway. Being six months pregnant, I’ve hired a professional gardener to remove 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.

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 crop rotation for edible gardens. But, the only things I’m picking from my garden right now are a few scrumped apples and some woody herbs.

My ambitions for the garden are modest and consistent – and enhancing soil health is my main priority. For those wondering, the scaffold is for roof repairs, and the fences are yet to be fixed, but the neighbours agree with the plan.

Cover crops work wonders for your garden’s foundation. Soil likes to be covered, which is why weeds appear. But by sowing vigorous crops, you can control weeds, bring in bees, shelter beneficial insects, and fix nitrogen.

Cover crops aren’t always showy – though some, like certain lupin varieties and bird’s foot trefoil, have pretty flowers – but their role is to thrive rather than be admired. After they’ve grown, you can turn them under, cut them for compost, or leave them on the surface for worms to pull down. Their work happens underground.

Autumn is perfect for sowing these overwintering crops. I’ve chosen forage rye, great for clay soil, Italian ryegrass, a weed-suppressor, and beans that aerate soil.

There’s satisfaction in sowing something knowing it’s temporary – on the surface, anyway.
