Soil in need of some love? Plant green manure in your garden and you’ll enrich your soil.

Just the other day, I discovered a partially finished 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 a bit of a mess. But there’s a lot to be said for negligence; coming back from a trip, I spotted a sunflower growing in the back corner.

Now, however, some urgent tidying is underway. As I’m expecting a baby, I’ve hired a local gardener to remove invasive plants like green alkanet and robinia saplings from the neighbour’s tree, while leaving the good stuff. Then, in the newly cleared patches, I’ll be sowing cover crops.

Green manure are superheroes 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 edible gardens. However, the only things I’m harvesting 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 top of the list. To update concerned readers, the scaffolding is for roof repairs, and the fences are still wobbly, but the neighbours agree with replacing them.

Green manure work wonders for soil health. Bare soil invites weeds, which is why weeds appear. But by sowing vigorous crops, you can suppress 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 lovely blooms – but their purpose 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 earthworms to incorporate. The real magic happens below the surface.

Now is the ideal time for sowing these overwintering crops. My selection includes rye grass, great for clay soil, Italian ryegrass, a weed-suppressor, and field beans.

It feels rewarding in sowing something knowing it’s temporary – at least above ground.
