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 Lucozade placed in the euphorbia trough by one of the scaffolders. A visiting architect joked, “Are you sure that’s Lucozade?” giving me a new perspective.

In short, the garden is a bit of a mess. Sometimes neglect has its perks; 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 a prickly weed and robinia saplings from the neighbour’s tree, but keeping desirable plants. Next, 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 previously discussed cover crops, as they are essential in crop rotation 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 ambitions for the garden are simple and steady – and improving the soil is top of the list. To update concerned readers, the scaffolding is for roof repairs, and the garden boundaries are still wobbly, but the neighbours are on board 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 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 a flowering legume, have pretty flowers – but their role is to thrive rather than be admired. Once established, you can dig them into the soil, cut them for compost, or let them decompose for worms to pull down. The real magic happens below the surface.

Now is the ideal time for sowing these overwintering crops. I’ve chosen rye grass, great for clay soil, Italian ryegrass, vetch, and field beans.

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