Soil in need of some love? Plant 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. An architect friend commented, “Are you sure that’s Lucozade?” giving me a new perspective.

In short, the garden is in disarray. Sometimes neglect has its perks; after returning from holiday, I spotted a sunflower sprouting 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 remove invasive plants like a prickly weed and robinia saplings from the neighbour’s tree, while leaving the good stuff. Next, 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 written about green manure, 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 garden goals are modest and consistent – and improving the soil is top of the list. To update concerned readers, the scaffold is for roof repairs, and the fences are yet to be fixed, but the neighbours agree with replacing them.

Cover crops work wonders for your garden’s foundation. Bare soil invites weeds, which is why weeds appear. But by sowing vigorous crops, you can suppress weeds, bring in bees, host pest-eating creatures, and enrich the soil with nutrients.

Cover crops aren’t always showy – though some, like certain lupin varieties and a flowering legume, have pretty flowers – but their purpose is to thrive rather than look decorative. After they’ve grown, you can dig them into the soil, chop them for mulch, or leave them on the surface for earthworms to pull down. The real magic happens below the surface.

Autumn is perfect for sowing these overwintering crops. I’ve chosen rye grass, which breaks up heavy earth, a nitrogen-lifter, vetch, and field beans.

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