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 half-empty bottle of an energy drink left behind in the euphorbia trough by one of the scaffolders. An architect friend commented, “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; coming back from a trip, I spotted a sunflower sprouting in the back corner.
This week, though, some necessary firefighting is underway. Being six months pregnant, 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 green manure.
Green manure are superheroes when it comes to improving soil health.
A fellow garden writer has written about green manure, as they are essential in seasonal planting for vegetable plots. However, the only things I’m picking from my garden right now are a few foraged apples and some woody herbs.
My garden goals are modest and consistent – and improving the soil is my main priority. For those wondering, the scaffold is for roof repairs, and the garden boundaries are yet to be fixed, but the neighbours agree with the plan.
Cover crops work wonders for soil health. Bare soil invites weeds, which is why unwanted plants pop up. But by sowing vigorous crops, you can control weeds, bring in bees, shelter beneficial insects, and fix nitrogen.
Green manure plants may not look exciting – though some, like certain lupin varieties and bird’s foot trefoil, have lovely blooms – but their role is to grow vigorously rather than be admired. After they’ve grown, you can turn them under, chop them for mulch, or let them decompose for worms to pull down. Their work happens underground.
Autumn is perfect for sowing these cold-season plants. I’ve chosen rye grass, great for clay soil, Italian ryegrass, vetch, and beans that aerate soil.
It feels rewarding in planting seeds that won’t stay forever – at least above ground.
