Does your garden soil need a boost? Plant green manure in your garden and you’ll improve your yields.
I recently found a half-empty 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 sprouting in the back corner.
Now, however, some urgent tidying is underway. Being six months pregnant, I’ve enlisted 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.
Green manure are superheroes when it comes to improving soil health.
My gardening friend Claire has previously discussed cover crops, 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 woody herbs.
My ambitions for the garden are simple and steady – and enhancing soil health is my main priority. For those wondering, the scaffolding is for roof repairs, and the fences are still wobbly, but the neighbours are on board with the plan.
Cover crops work wonders for soil health. Bare soil invites weeds, which is why unwanted plants pop up. Yet by sowing vigorous crops, you can control weeds, bring in bees, shelter beneficial insects, and fix nitrogen.
Green manure plants aren’t always showy – though some, like lupins ‘Blue Sonet’ and a flowering legume, have pretty flowers – but their role is to thrive rather than be admired. After they’ve grown, you can turn them under, chop them for mulch, or leave them on the surface for worms to incorporate. The real magic happens below the surface.
Autumn is perfect for sowing these overwintering crops. My selection includes forage rye, which breaks up heavy earth, Italian ryegrass, vetch, and field beans.
There’s satisfaction in planting seeds that won’t stay forever – at least above ground.
