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

I recently found a partially finished bottle of Lucozade placed in the euphorbia trough by one of the scaffolders. An architect friend joked, “Are you sure that’s Lucozade?” giving me a new perspective.

In short, the garden is in disarray. Sometimes neglect has its perks; coming back from a trip, I spotted a sunflower growing in the back corner.

Now, however, some necessary firefighting is underway. As I’m expecting a baby, I’ve hired a local gardener to tackle troublesome weeds 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 improving soil health.

My gardening friend Claire has previously discussed cover crops, as they play a key role in crop rotation for edible gardens. However, the only things I’m picking from my garden right now are a few foraged apples and some woody herbs.

My ambitions for the garden are modest and consistent – and improving the soil is top of the list. For those wondering, the scaffolding is for roof repairs, and the fences are still wobbly, but the neighbours agree with the plan.

Cover crops work wonders for soil health. Bare soil invites weeds, which is why unwanted plants pop up. Yet by sowing fast-growing plants, you can control weeds, attract pollinators, shelter beneficial insects, and fix nitrogen.

Cover crops may not look exciting – though some, like certain lupin varieties 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 earthworms to pull down. The real magic happens underground.

Autumn is perfect for sowing these cold-season plants. My selection includes forage rye, which breaks up heavy earth, a nitrogen-lifter, a weed-suppressor, and field beans.

There’s satisfaction in sowing something knowing it’s temporary – at least above ground.
