Does your garden soil need a boost? Plant 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. A visiting architect 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; coming back from a trip, I spotted a sunflower growing in the back corner.

Now, however, some urgent tidying is underway. Being six months pregnant, I’ve hired a local gardener to remove invasive plants like a prickly weed 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 improving soil health.

My gardening friend Claire has previously discussed green manure, as they play a key role in seasonal planting for edible gardens. But, the only things I’m picking from my garden right now are a few scrumped apples and some hardy herbs.

My ambitions for the garden are modest and consistent – and enhancing soil health is top of the list. For those wondering, the scaffolding is for roof repairs, and the garden boundaries are still wobbly, but the neighbours agree with replacing them.

Cover crops work wonders for your garden’s foundation. Soil likes to be covered, which is why weeds appear. But by sowing vigorous crops, you can suppress weeds, bring in bees, shelter beneficial insects, and enrich the soil with nutrients.

Green manure plants may not look exciting – though some, like certain lupin varieties and a flowering legume, have pretty flowers – but their role is to grow vigorously rather than look decorative. Once established, you can turn them under, chop them for mulch, or let them decompose 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 rye grass, great for clay soil, Italian ryegrass, a weed-suppressor, and beans that aerate soil.

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