Soil in need of some love? 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. A visiting architect joked, “Are you sure that’s Lucozade?” which made me see it differently.
In short, 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 urgent tidying is underway. Being six months pregnant, I’ve enlisted a professional gardener to tackle invasive plants like a prickly weed and robinia saplings from the neighbour’s tree, but keeping desirable plants. Then, in the open patches, I’ll be sowing cover crops.
Cover crops act like heroes when it comes to improving soil health.
My gardening friend Claire has previously discussed green manure, as they play a key role in seasonal planting 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 garden goals are simple and steady – and improving the soil is top of the list. To update concerned readers, the scaffolding is for roof repairs, and the garden boundaries are yet to be fixed, but the neighbours are on board with the plan.
Cover crops work wonders for soil health. Bare soil invites weeds, which is why weeds appear. Yet by sowing vigorous crops, you can suppress weeds, attract pollinators, host pest-eating creatures, and fix nitrogen.
Green manure plants aren’t always showy – though some, like certain lupin varieties and bird’s foot trefoil, have lovely blooms – but their purpose is to thrive rather than look decorative. Once established, you can dig them into the soil, cut them for compost, or let them decompose for worms to incorporate. Their work happens underground.
Autumn is perfect for sowing these overwintering crops. I’ve chosen forage rye, great for clay soil, a nitrogen-lifter, a weed-suppressor, and field beans.
There’s satisfaction in planting seeds that won’t stay forever – at least above ground.
