Does your garden soil need a boost? Sow green manure in your garden and you’ll improve your yields.

I recently found a partially finished bottle of an energy drink left behind in the euphorbia trough by one of the scaffolders. An architect friend joked, “Are you sure that’s Lucozade?” giving me a new perspective.

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.

Now, however, some necessary firefighting is underway. As I’m expecting a baby, I’ve enlisted a local gardener to tackle invasive plants like a prickly weed and robinia saplings from the neighbour’s tree, while leaving the good stuff. Next, in the newly cleared patches, I’ll be sowing cover crops.

Green manure are superheroes 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 vegetable plots. But, the only things I’m picking from my garden right now are a few scrumped apples and some woody herbs.

My garden goals are simple and steady – and improving the soil is top of the list. For those wondering, the scaffold is for roof repairs, and the garden boundaries are still wobbly, but the neighbours are on board with the plan.

Cover crops are like superheroes for soil health. Soil likes to be covered, which is why weeds appear. But by sowing vigorous crops, you can control weeds, attract pollinators, host pest-eating creatures, and enrich the soil with nutrients.

Cover crops may not look exciting – though some, like lupins ‘Blue Sonet’ and bird’s foot trefoil, have pretty flowers – but their role is to grow vigorously rather than be admired. 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.

Now is the ideal time for sowing these cold-season plants. I’ve chosen rye grass, which breaks up heavy earth, a nitrogen-lifter, a weed-suppressor, and field beans.

It feels rewarding in sowing something that won’t stay forever – at least above ground.
