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 Lucozade left behind in the euphorbia trough by one of the scaffolders. A visiting architect commented, “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; after returning from holiday, I spotted a sunflower growing in the back corner.

This week, though, some necessary firefighting is underway. As I’m expecting a baby, I’ve hired a local 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 improving soil health.

My gardening friend Claire has previously discussed green manure, as they are essential in seasonal planting for vegetable plots. But, the only things I’m harvesting from my garden right now are a few foraged apples and some woody herbs.

My garden goals are simple and steady – and improving the soil is my main priority. For those wondering, 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. Soil likes to be covered, which is why unwanted plants pop up. Yet by sowing fast-growing plants, you can control weeds, bring in bees, host pest-eating creatures, and fix nitrogen.

Green manure plants may not look exciting – though some, like lupins ‘Blue Sonet’ and bird’s foot trefoil, have lovely blooms – but their purpose is to thrive rather than be admired. Once established, you can turn them under, cut them for compost, or leave them on the surface for earthworms to incorporate. The real magic happens below the surface.

Now is the ideal time for sowing these overwintering crops. My selection includes forage rye, great for clay soil, a nitrogen-lifter, vetch, and beans that aerate soil.

It feels rewarding in planting seeds that won’t stay forever – on the surface, anyway.
