Soil in need of some love? Sow cover crops in your garden and you’ll improve your yields.

I recently found a partially finished bottle of an energy drink placed in the euphorbia trough by one of the scaffolders. A visiting architect commented, “Are you sure that’s Lucozade?” giving me a new perspective.

All this is to say, the garden is in disarray. Sometimes neglect has its perks; after returning from holiday, I spotted a sunflower growing in the back corner.

Now, however, some urgent tidying is underway. As I’m expecting a baby, I’ve hired a local gardener to remove troublesome weeds like green alkanet and robinia saplings from the neighbour’s tree, while leaving the good stuff. Next, in the newly cleared patches, I’ll be sowing green manure.

Cover crops act like heroes when it comes to boosting soil quality.

A fellow garden writer has written about cover crops, as they play a key role in seasonal planting for edible gardens. However, the only things I’m picking from my garden right now are a few scrumped apples and some woody herbs.

My ambitions for the garden are simple and steady – and improving the soil is top of the list. For those wondering, the scaffold is for roof repairs, and the garden boundaries are still wobbly, but the neighbours are on board with replacing them.

Green manure work wonders for soil health. Soil likes to be covered, which is why weeds appear. But by sowing vigorous crops, you can control weeds, bring in bees, shelter beneficial insects, and fix nitrogen.

Green manure plants 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. After they’ve grown, you can dig them into the soil, cut them for compost, or leave them on the surface for earthworms to incorporate. The real magic happens underground.

Now is the ideal time for sowing these cold-season plants. My selection includes rye grass, great for clay soil, Italian ryegrass, a weed-suppressor, and beans that aerate soil.

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