Soil in need of some love? Sow green manure in your garden and you’ll reap the benefits.

I recently found a partially finished bottle of Lucozade 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.

In short, the garden is in disarray. Sometimes neglect has its perks; after returning from holiday, I spotted a sunflower sprouting in the back corner.

Now, however, some necessary firefighting is underway. Being six months pregnant, I’ve hired a local gardener to tackle invasive plants like a prickly weed and robinia saplings from the neighbour’s tree, but keeping desirable plants. Then, in the newly cleared patches, I’ll be sowing green manure.

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 hardy herbs.

My garden goals are simple and steady – and improving the soil is my main priority. To update concerned readers, the scaffolding is for roof repairs, and the garden boundaries are yet to be fixed, but the neighbours agree with the plan.

Green manure work wonders for soil health. Bare soil invites weeds, which is why weeds appear. But by sowing fast-growing plants, you can suppress weeds, attract pollinators, shelter beneficial insects, and enrich the soil with nutrients.

Cover crops aren’t always showy – though some, like certain lupin varieties and bird’s foot trefoil, have pretty flowers – but their role is to thrive rather than be admired. Once established, you can dig them into the soil, chop them for mulch, or leave them on the surface for earthworms to pull down. Their work happens below the surface.

Now is the ideal time for sowing these cold-season plants. I’ve chosen forage rye, which breaks up heavy earth, Italian ryegrass, vetch, and beans that aerate soil.

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