Does your garden soil need a boost? Sow green manure in your garden and you’ll improve your yields.
I recently found a half-empty bottle of an energy drink 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.
All this is to say, the garden is in disarray. Sometimes neglect has its perks; coming back from a trip, I spotted a sunflower growing in the back corner.
This week, though, some necessary firefighting is underway. As I’m expecting a baby, I’ve hired a professional gardener to tackle invasive plants 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 improving soil health.
A fellow garden writer has previously discussed green manure, as they play a key role in crop rotation for vegetable plots. 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 modest and consistent – and improving the soil is my main priority. To update concerned readers, the scaffolding is for roof repairs, and the garden boundaries are still wobbly, but the neighbours agree with the plan.
Green manure are like superheroes for your garden’s foundation. Soil likes to be covered, which is why unwanted plants pop up. Yet by sowing vigorous crops, 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 bird’s foot trefoil, have lovely blooms – but their role is to grow vigorously 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 pull down. Their work happens below the surface.
Autumn is perfect for sowing these overwintering crops. My selection includes forage rye, great for clay soil, a nitrogen-lifter, vetch, and beans that aerate soil.
It feels rewarding in sowing something that won’t stay forever – at least above ground.
