Want to give your soil some TLC? Sow green manure in your garden and you’ll improve your yields.
Just the other day, I discovered a partially finished bottle of an energy drink placed in the euphorbia trough by one of the scaffolders. A visiting architect joked, “Are you sure that’s Lucozade?” giving me a new perspective.
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.
Now, however, some necessary firefighting is underway. As I’m expecting a baby, I’ve hired a professional gardener to remove troublesome weeds like green alkanet and robinia saplings from the neighbour’s tree, but keeping desirable plants. Next, in the open patches, I’ll be sowing green manure.
Cover crops act like heroes when it comes to improving soil health.
A fellow garden writer has previously discussed cover crops, as they play a key role in crop rotation for edible gardens. However, the only things I’m picking from my garden right now are a few scrumped apples and some hardy herbs.
My ambitions for the garden are modest and consistent – and enhancing soil health is top of the list. To update concerned readers, the scaffolding is for roof repairs, and the fences are still wobbly, but the neighbours are on board with replacing them.
Green manure work wonders for soil health. Soil likes to be covered, which is why unwanted plants pop up. Yet by sowing vigorous crops, you can suppress weeds, bring in bees, host pest-eating creatures, and fix nitrogen.
Cover crops aren’t always showy – though some, like lupins ‘Blue Sonet’ and a flowering legume, have pretty flowers – but their role is to thrive rather than be admired. Once established, you can dig them into the soil, chop them for mulch, or leave them on the surface for earthworms to incorporate. Their work happens underground.
Autumn is perfect for sowing these cold-season plants. My selection includes rye grass, great for clay soil, a nitrogen-lifter, a weed-suppressor, and field beans.
It feels rewarding in planting seeds that won’t stay forever – on the surface, anyway.
