Soil in need of some love? Sow green manure in your garden and you’ll enrich your soil.

Just the other day, I discovered a half-empty bottle of Lucozade placed in the euphorbia trough by one of the scaffolders. An architect friend joked, “Are you sure that’s Lucozade?” which made me see it differently.

All this is to say, 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.

This week, though, some urgent tidying is underway. As I’m expecting a baby, I’ve enlisted a professional gardener to remove invasive plants like green alkanet and robinia saplings from the neighbour’s tree, but keeping desirable plants. Then, in the newly cleared patches, I’ll be sowing green manure.

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

My gardening friend Claire has previously discussed cover crops, as they are essential in crop rotation for edible gardens. But, the only things I’m harvesting from my garden right now are a few foraged 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 scaffolding is for roof repairs, and the fences are yet to be fixed, but the neighbours agree with replacing them.

Green manure work wonders for soil health. Soil likes to be covered, 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.

Green manure plants aren’t always showy – though some, like lupins ‘Blue Sonet’ and a flowering legume, have pretty flowers – but their purpose is to thrive rather than be admired. Once established, you can turn them under, cut them for compost, or let them decompose for worms to incorporate. Their work happens underground.

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 planting seeds knowing it’s temporary – on the surface, anyway.
