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

I recently found a partially finished 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.

In short, the garden is in disarray. But there’s a lot to be said for negligence; coming back from a trip, I spotted a sunflower growing in the back corner.

This week, though, some urgent tidying is underway. As I’m expecting a baby, I’ve hired a professional gardener to remove invasive plants like a prickly weed and young tree shoots from the neighbour’s tree, but keeping desirable plants. Then, in the open patches, I’ll be sowing cover crops.

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

My gardening friend Claire has previously discussed cover crops, 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 simple and steady – and improving the soil is top of the list. To update concerned readers, the scaffold is for roof repairs, and the fences are still wobbly, but the neighbours agree with replacing them.

Green manure are like superheroes for soil health. Bare soil invites weeds, which is why unwanted plants pop up. But by sowing fast-growing plants, you can suppress weeds, bring in bees, shelter beneficial insects, and enrich the soil with nutrients.

Cover crops may not look exciting – though some, like certain lupin varieties and a flowering legume, have pretty flowers – but their purpose 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 incorporate. The real magic happens underground.

Autumn is perfect for sowing these overwintering crops. My selection includes rye grass, great for clay soil, a nitrogen-lifter, vetch, and beans that aerate soil.

There’s satisfaction in planting seeds that won’t stay forever – at least above ground.
