Does your garden soil need a boost? Plant green manure in your garden and you’ll improve your yields.

Just the other day, I discovered a partially finished 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. Sometimes neglect has its perks; coming back from a trip, 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 professional gardener to remove invasive plants like a prickly weed and robinia saplings from the neighbour’s tree, while leaving the good stuff. Then, in the newly cleared patches, I’ll be sowing cover crops.

Green manure are superheroes 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 vegetable plots. However, the only things I’m harvesting from my garden right now are a few foraged apples and some woody herbs.

My ambitions for the garden are simple and steady – and enhancing soil health is top of the list. To update concerned readers, the scaffold is for roof repairs, and the fences are still wobbly, but the neighbours agree with the plan.

Cover crops work wonders for soil health. Bare soil invites weeds, which is why unwanted plants pop up. Yet by sowing vigorous crops, you can suppress weeds, bring in bees, shelter beneficial insects, and enrich the soil with nutrients.

Green manure plants may not look exciting – though some, like certain lupin varieties and a flowering legume, 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 worms 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, a nitrogen-lifter, vetch, and field beans.

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