Soil in need of some love? Plant cover crops 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 joked, “Are you sure that’s Lucozade?” which made me see it differently.
In short, the garden is in disarray. 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 necessary firefighting is underway. Being six months pregnant, I’ve enlisted a professional gardener to tackle troublesome weeds like green alkanet and young tree shoots from the neighbour’s tree, but keeping desirable plants. Next, 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 written about cover crops, as they play a key role in crop rotation for edible gardens. But, 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 simple and steady – and enhancing soil health is my main priority. For those wondering, the scaffold is for roof repairs, and the garden boundaries are still wobbly, but the neighbours are on board with replacing them.
Cover crops work wonders for soil health. Soil likes to be covered, which is why weeds appear. Yet by sowing vigorous crops, you can suppress weeds, bring in bees, shelter beneficial insects, and fix nitrogen.
Green manure plants aren’t always showy – though some, like certain lupin varieties and bird’s foot trefoil, 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 cold-season plants. I’ve chosen rye grass, which breaks up heavy earth, Italian ryegrass, a weed-suppressor, and beans that aerate soil.
There’s satisfaction in planting seeds that won’t stay forever – on the surface, anyway.
