Does your garden soil need a boost? Sow green manure in your garden and you’ll reap the benefits.
I recently found a half-empty bottle of an energy drink left behind in the euphorbia trough by one of the scaffolders. A visiting architect 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 sprouting in the back corner.
This week, though, some urgent tidying is underway. As I’m expecting a baby, 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 cover crops.
Cover crops act like heroes when it comes to improving soil health.
My gardening friend Claire has previously discussed cover crops, as they play a key role in crop rotation for vegetable plots. But, the only things I’m harvesting from my garden right now are a few foraged apples and some woody herbs.
My garden goals are modest and consistent – and enhancing soil health is top of the list. For those wondering, the scaffold is for roof repairs, and the fences are yet to be fixed, but the neighbours are on board with replacing them.
Cover crops are like superheroes for your garden’s foundation. Soil likes to be covered, which is why weeds appear. Yet by sowing fast-growing plants, you can suppress weeds, attract pollinators, host pest-eating creatures, and fix nitrogen.
Green manure plants aren’t always showy – though some, like lupins ‘Blue Sonet’ and a flowering legume, have pretty flowers – but their role is to grow vigorously rather than be admired. Once established, you can dig them into the soil, chop them for mulch, or let them decompose for worms to pull down. Their work happens below the surface.
Now is the ideal time for sowing these overwintering crops. I’ve chosen rye grass, great for clay soil, a nitrogen-lifter, a weed-suppressor, and beans that aerate soil.
It feels rewarding in planting seeds that won’t stay forever – at least above ground.
