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

I recently found a half-empty 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.

This week, though, some urgent tidying is underway. As I’m expecting a baby, I’ve enlisted 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 newly cleared patches, I’ll be sowing green manure.

Green manure are superheroes when it comes to improving soil health.

My gardening friend Claire has written about green manure, as they are essential in seasonal planting for vegetable plots. However, the only things I’m harvesting from my garden right now are a few scrumped apples and some hardy herbs.

My garden goals are simple and steady – and enhancing soil health is top of the list. For those wondering, the scaffold is for roof repairs, and the garden boundaries are yet to be fixed, but the neighbours agree with the plan.

Cover crops work wonders for your garden’s foundation. Soil likes to be covered, which is why weeds appear. Yet 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 a flowering legume, have lovely blooms – but their role is to thrive rather than be admired. Once established, you can turn them under, chop them for mulch, or let them decompose for earthworms to pull down. The real magic happens underground.

Now is the ideal time for sowing these overwintering crops. I’ve chosen rye grass, which breaks up heavy earth, Italian ryegrass, a weed-suppressor, and field beans.

There’s satisfaction in planting seeds knowing it’s temporary – on the surface, anyway.
