Soil in need of some love? Plant green manure in your garden and you’ll improve your yields.
Just the other day, I discovered a partially finished bottle of Lucozade left behind in the euphorbia trough by one of the scaffolders. An architect friend joked, “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. Being six months pregnant, I’ve hired a local gardener to remove troublesome weeds 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 green manure.
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 vegetable plots. However, the only things I’m harvesting from my garden right now are a few foraged 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 scaffolding is for roof repairs, and the garden boundaries are yet to be fixed, but the neighbours are on board with the plan.
Cover crops are like superheroes for your garden’s foundation. Soil likes to be covered, which is why weeds appear. But by sowing fast-growing plants, you can control weeds, attract pollinators, host pest-eating creatures, and fix nitrogen.
Green manure plants may not look exciting – though some, like lupins ‘Blue Sonet’ and a flowering legume, have pretty flowers – but their role is to thrive rather than look decorative. After they’ve grown, you can dig them into the soil, chop them for mulch, or leave them on the surface for earthworms to incorporate. Their work happens below the surface.
Autumn is perfect for sowing these overwintering crops. I’ve chosen forage rye, great for clay soil, a nitrogen-lifter, vetch, and field beans.
It feels rewarding in planting seeds knowing it’s temporary – at least above ground.
