Want to give your soil some TLC? Plant cover crops in your garden and you’ll enrich your soil.

I recently found a partially finished bottle of Lucozade placed in the euphorbia trough by one of the scaffolders. A visiting architect commented, “Are you sure that’s Lucozade?” which made me see it differently.

In short, the garden is a bit of a mess. But there’s a lot to be said for negligence; after returning from holiday, I spotted a sunflower sprouting in the back corner.

Now, however, some necessary firefighting is underway. Being six months pregnant, I’ve enlisted a professional gardener to remove troublesome weeds like green alkanet and young tree shoots from the neighbour’s tree, while leaving the good stuff. Next, in the open patches, I’ll be sowing green manure.

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

My gardening friend Claire has previously discussed green manure, as they are essential 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 woody herbs.

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

Green manure are like superheroes for soil health. Soil likes to be covered, which is why weeds appear. Yet by sowing vigorous crops, you can suppress weeds, attract pollinators, host pest-eating creatures, and fix nitrogen.

Green manure plants aren’t always showy – though some, like certain lupin varieties and bird’s foot trefoil, have pretty flowers – but their role 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 earthworms to pull down. Their work happens below the surface.

Now is the ideal time for sowing these cold-season plants. I’ve chosen forage rye, which breaks up heavy earth, Italian ryegrass, a weed-suppressor, and beans that aerate soil.

There’s satisfaction in sowing something knowing it’s temporary – at least above ground.
