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

I recently found a half-empty bottle of Lucozade left behind 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; after returning from holiday, 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 enlisted a professional gardener to remove invasive plants like green alkanet and robinia saplings from the neighbour’s tree, while leaving the good stuff. Then, in the open patches, I’ll be sowing green manure.

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

A fellow garden writer has written about cover crops, as they play a key role in seasonal planting for vegetable plots. However, the only things I’m picking from my garden right now are a few scrumped apples and some woody herbs.

My ambitions for the garden are modest and consistent – and enhancing soil health is top of the list. To update concerned readers, the scaffold is for roof repairs, and the fences are still wobbly, but the neighbours are on board with the plan.

Cover crops work wonders for soil health. Soil likes to be covered, which is why unwanted plants pop up. But by sowing vigorous crops, you can suppress weeds, bring in bees, shelter beneficial insects, and enrich the soil with nutrients.

Green manure plants aren’t always showy – though some, like lupins ‘Blue Sonet’ and bird’s foot trefoil, have lovely blooms – but their purpose is to thrive rather than look decorative. Once established, you can dig them into the soil, cut them for compost, or let them decompose for worms to pull down. Their work happens underground.

Now is the ideal time for sowing these cold-season plants. I’ve chosen forage rye, great for clay soil, Italian ryegrass, vetch, and field beans.

It feels rewarding in planting seeds knowing it’s temporary – on the surface, anyway.
