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

Just the other day, I discovered a partially finished bottle of an energy drink left behind 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.

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

Now, however, some necessary firefighting is underway. As I’m expecting a baby, I’ve enlisted a professional gardener to tackle invasive plants like a prickly weed and robinia saplings from the neighbour’s tree, but keeping desirable plants. Next, in the open patches, I’ll be sowing green manure.

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

My gardening friend Claire has written about 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 scrumped apples and some hardy herbs.

My ambitions for the garden are simple and steady – and enhancing soil health is my main priority. For those wondering, the scaffold is for roof repairs, and the garden boundaries are yet to be fixed, but the neighbours agree with replacing them.

Green manure are like superheroes for soil health. Soil likes to be covered, which is why weeds appear. But by sowing vigorous crops, you can suppress weeds, attract pollinators, shelter beneficial insects, and enrich the soil with nutrients.

Cover crops may not look exciting – though some, like lupins ‘Blue Sonet’ and bird’s foot trefoil, have lovely blooms – but their purpose is to thrive rather than look decorative. Once established, you can turn them under, chop them for mulch, or let them decompose for earthworms to pull down. Their work happens below the surface.

Autumn is perfect for sowing these cold-season plants. I’ve chosen forage rye, which breaks up heavy earth, Italian ryegrass, a weed-suppressor, and beans that aerate soil.

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