Soil in need of some love? Sow green manure in your garden and you’ll enrich your soil.
Just the other day, I discovered a partially finished bottle of an energy drink placed in the euphorbia trough by one of the scaffolders. An architect friend joked, “Are you sure that’s Lucozade?” which made me see it differently.
In short, the garden is a bit of a mess. Sometimes neglect has its perks; after returning from holiday, 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 local gardener to remove troublesome weeds like green alkanet 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 crop rotation for edible gardens. However, the only things I’m harvesting 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 scaffolding is for roof repairs, and the fences are yet to be fixed, but the neighbours are on board with the plan.
Green manure are like superheroes for soil health. Soil likes to be covered, which is why unwanted plants pop up. Yet by sowing vigorous crops, you can control weeds, bring in bees, shelter beneficial insects, and enrich the soil with nutrients.
Green manure plants aren’t always showy – though some, like lupins ‘Blue Sonet’ and a flowering legume, have lovely blooms – but their purpose 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 earthworms to incorporate. Their work happens underground.
Autumn is perfect for sowing these cold-season plants. I’ve chosen forage rye, great for clay soil, a nitrogen-lifter, vetch, and beans that aerate soil.
There’s satisfaction in planting seeds knowing it’s temporary – at least above ground.
