Want to give your soil some TLC? Sow green manure in your garden and you’ll reap the benefits.
I recently found a partially finished bottle of an energy drink left behind in the euphorbia trough by one of the scaffolders. A visiting architect joked, “Are you sure that’s Lucozade?” which made me see it differently.
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 growing in the back corner.
This week, though, some urgent tidying is underway. As I’m expecting a baby, I’ve hired a professional gardener to remove troublesome weeds like a prickly weed and young tree shoots from the neighbour’s tree, but keeping desirable plants. Then, in the newly cleared patches, I’ll be sowing green manure.
Cover crops act like heroes 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. But, the only things I’m picking from my garden right now are a few foraged apples and some hardy herbs.
My ambitions for the garden are simple and steady – and enhancing soil health is my main priority. To update concerned readers, the scaffold is for roof repairs, and the garden boundaries are still wobbly, but the neighbours are on board with replacing them.
Green manure are like superheroes for soil health. Soil likes to be covered, which is why weeds appear. Yet by sowing fast-growing plants, you can suppress weeds, bring in bees, shelter beneficial insects, and enrich the soil with nutrients.
Green manure plants aren’t always showy – though some, like lupins ‘Blue Sonet’ and a flowering legume, have lovely blooms – but their role is to thrive rather than look decorative. Once established, you can dig them into the soil, chop them for mulch, or leave them on the surface for worms to incorporate. Their work happens underground.
Autumn is perfect for sowing these overwintering crops. I’ve chosen rye grass, which breaks up heavy earth, Italian ryegrass, vetch, and field beans.
It feels rewarding in sowing something that won’t stay forever – at least above ground.
