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 a bit of a mess. But there’s a lot to be said for negligence; after returning from holiday, 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 remove invasive plants like green alkanet and robinia saplings from the neighbour’s tree, but keeping desirable plants. Then, in the newly cleared patches, I’ll be sowing cover crops.
Cover crops act like heroes when it comes to boosting soil quality.
A fellow garden writer has previously discussed green manure, as they are essential in crop rotation for edible gardens. However, the only things I’m picking from my garden right now are a few foraged apples and some hardy herbs.
My garden goals are modest and consistent – and enhancing soil health is my main priority. To update concerned readers, the scaffold is for roof repairs, and the fences are still wobbly, but the neighbours agree with the plan.
Cover crops are like superheroes for soil health. Bare soil invites weeds, which is why weeds appear. But by sowing fast-growing plants, you can control weeds, attract pollinators, host pest-eating creatures, and enrich the soil with nutrients.
Cover crops aren’t always showy – though some, like certain lupin varieties and bird’s foot trefoil, have lovely blooms – but their role is to grow vigorously rather than look decorative. Once established, you can turn them under, cut them for compost, or leave them on the surface for earthworms to incorporate. Their work happens underground.
Autumn is perfect for sowing these overwintering crops. I’ve chosen forage rye, great for clay soil, Italian ryegrass, vetch, and field beans.
It feels rewarding in sowing something that won’t stay forever – on the surface, anyway.
