Want to give your soil some TLC? Plant green manure in your garden and you’ll reap the benefits.
I recently found a half-empty bottle of Lucozade placed in the euphorbia trough by one of the scaffolders. A visiting architect commented, “Are you sure that’s Lucozade?” giving me a new perspective.
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 urgent tidying is underway. As I’m expecting a baby, I’ve hired a professional gardener to tackle troublesome weeds like green alkanet and young tree shoots 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 cover crops, as they are essential in crop rotation for edible gardens. But, the only things I’m harvesting from my garden right now are a few scrumped apples and some woody herbs.
My garden goals are simple and steady – and enhancing soil health is my main priority. To update concerned readers, the scaffold is for roof repairs, and the fences are still wobbly, but the neighbours agree with the plan.
Green manure work wonders 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, bring in bees, host pest-eating creatures, and fix nitrogen.
Cover crops aren’t always showy – though some, like lupins ‘Blue Sonet’ and bird’s foot trefoil, have pretty flowers – but their purpose is to thrive rather than look decorative. After they’ve grown, you can dig them into the soil, chop them for mulch, or leave them on the surface for worms to pull down. Their work happens below the surface.
Autumn is perfect for sowing these overwintering crops. My selection includes rye grass, which breaks up heavy earth, a nitrogen-lifter, vetch, and field beans.
There’s satisfaction in planting seeds that won’t stay forever – on the surface, anyway.
