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

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 a bit of a mess. But there’s a lot to be said for negligence; coming back from a trip, I spotted a sunflower sprouting in the back corner.

This week, though, some necessary firefighting is underway. As I’m expecting a baby, I’ve hired a professional gardener to tackle invasive plants like green alkanet and robinia saplings from the neighbour’s tree, but keeping desirable plants. Then, in the open patches, I’ll be sowing green manure.

Cover crops act like heroes when it comes to boosting soil quality.

My gardening friend Claire has written about 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 scrumped apples and some woody herbs.

My garden goals are simple and steady – and improving the soil is top of the list. To update concerned readers, the scaffold is for roof repairs, and the fences are still wobbly, but the neighbours agree with the plan.

Cover crops are like superheroes for soil health. Soil likes to be covered, which is why unwanted plants pop up. But by sowing fast-growing plants, you can control weeds, attract pollinators, 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 role is to grow vigorously rather than look decorative. Once established, you can turn them under, cut them for compost, or leave them on the surface for earthworms to incorporate. The real magic happens underground.

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

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