Does your garden soil need a boost? Sow green manure in your garden and you’ll improve your yields.
Just the other day, I discovered a partially finished bottle of Lucozade placed in the euphorbia trough by one of the scaffolders. A visiting architect commented, “Are you sure that’s Lucozade?” giving me a new perspective.
All this is to say, the garden is a bit of a mess. Sometimes neglect has its perks; coming back from a trip, 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 enlisted a professional gardener to remove troublesome weeds like green alkanet and young tree shoots from the neighbour’s tree, while leaving the good stuff. Then, in the open patches, I’ll be sowing cover crops.
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 seasonal planting for edible gardens. But, the only things I’m harvesting from my garden right now are a few scrumped apples and some hardy herbs.
My garden goals are modest and consistent – and improving the soil is top of the list. To update concerned readers, the scaffold is for roof repairs, and the garden boundaries are still wobbly, but the neighbours agree with replacing them.
Green manure are like superheroes for soil health. Bare soil invites weeds, which is why unwanted plants pop up. Yet by sowing fast-growing plants, you can suppress weeds, attract pollinators, host pest-eating creatures, and fix nitrogen.
Green manure plants aren’t always showy – 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 incorporate. The real magic happens underground.
Autumn is perfect for sowing these cold-season plants. I’ve chosen rye grass, great for clay soil, Italian ryegrass, a weed-suppressor, and beans that aerate soil.
There’s satisfaction in sowing something that won’t stay forever – at least above ground.
