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

Just the other day, I discovered a partially finished bottle of Lucozade left behind 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.

All this is to say, the garden is a bit of a mess. Sometimes neglect has its perks; 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 local gardener to tackle invasive plants like a prickly weed and robinia saplings from the neighbour’s tree, but keeping desirable plants. Next, in the newly cleared 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 play a key role in crop rotation 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 modest and consistent – and improving the soil is my main priority. For those wondering, the scaffold is for roof repairs, and the fences are yet to be fixed, but the neighbours are on board with replacing them.

Cover crops work wonders for your garden’s foundation. Bare soil invites weeds, which is why unwanted plants pop up. But by sowing vigorous crops, you can suppress weeds, attract pollinators, shelter beneficial insects, and fix nitrogen.

Green manure plants may not look exciting – though some, like certain lupin varieties and bird’s foot trefoil, have pretty flowers – but their purpose is to grow vigorously rather than look decorative. Once established, you can turn them under, chop them for mulch, or let them decompose for earthworms to incorporate. The real magic happens below the surface.

Autumn is perfect 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.
