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

I recently found a half-empty bottle of an energy drink 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.

All this is to say, 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.

This week, though, some necessary firefighting is underway. As I’m expecting a baby, I’ve enlisted a local gardener to tackle troublesome weeds like green alkanet and robinia saplings from the neighbour’s tree, but keeping desirable plants. Next, in the open patches, I’ll be sowing cover crops.

Green manure are superheroes when it comes to boosting soil quality.

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

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

Green manure work wonders for soil health. Bare soil invites weeds, which is why weeds appear. But by sowing vigorous crops, you can suppress weeds, attract pollinators, host pest-eating creatures, and enrich the soil with nutrients.

Green manure plants may not look exciting – though some, like lupins ‘Blue Sonet’ and a flowering legume, have lovely blooms – but their purpose is to thrive rather than look decorative. After they’ve grown, you can dig them into the soil, cut them for compost, or leave them on the surface for worms to incorporate. Their work happens underground.

Autumn is perfect for sowing these overwintering crops. My selection includes forage rye, which breaks up heavy earth, a nitrogen-lifter, vetch, and field beans.

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