Want to give your soil some TLC? Plant green manure in your garden and you’ll reap the benefits.

Just the other day, I discovered a partially finished bottle of Lucozade placed in the euphorbia trough by one of the scaffolders. A visiting architect joked, “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; coming back from a trip, I spotted a sunflower growing in the back corner.

Now, however, some necessary firefighting is underway. As I’m expecting a baby, I’ve enlisted a local gardener to tackle troublesome weeds like a prickly weed and young tree shoots from the neighbour’s tree, while leaving the good stuff. Next, in the newly cleared patches, I’ll be sowing cover crops.

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

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 harvesting from my garden right now are a few foraged apples and some hardy herbs.

My garden goals are simple and steady – and enhancing soil health is my main priority. To update concerned readers, the scaffold is for roof repairs, and the garden boundaries are still wobbly, but the neighbours are on board with the plan.

Cover crops are like superheroes for soil health. Bare soil invites weeds, which is why weeds appear. Yet by sowing fast-growing plants, you can suppress weeds, bring in bees, host pest-eating creatures, and fix nitrogen.

Cover crops may not look exciting – though some, like certain lupin varieties and a flowering legume, have pretty flowers – but their role is to grow vigorously rather than be admired. Once established, you can dig them into the soil, chop them for mulch, or let them decompose for earthworms to incorporate. Their work happens below the surface.

Now is the ideal time for sowing these overwintering crops. My selection includes rye grass, great for clay soil, Italian ryegrass, vetch, and field beans.

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