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 half-empty 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 in disarray. But there’s a lot to be said for negligence; after returning from holiday, I spotted a sunflower growing in the back corner.

Now, however, some urgent tidying is underway. As I’m expecting a baby, I’ve hired a professional gardener to tackle troublesome weeds 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 improving soil health.

A fellow garden writer has previously discussed green manure, as they play a key role in seasonal planting for edible gardens. However, the only things I’m picking from my garden right now are a few scrumped apples and some hardy herbs.

My ambitions for the garden are simple and steady – and improving the soil is my main priority. To update concerned readers, the scaffold is for roof repairs, and the fences are yet to be fixed, but the neighbours are on board with the plan.

Cover crops work wonders for soil health. Bare soil invites weeds, which is why weeds appear. But by sowing fast-growing plants, you can suppress weeds, attract pollinators, shelter beneficial insects, and fix nitrogen.

Cover crops may not look exciting – though some, like lupins ‘Blue Sonet’ and a flowering legume, have pretty flowers – but their role is to grow vigorously rather than be admired. After they’ve grown, you can turn them under, chop them for mulch, or let them decompose for earthworms to pull down. The real magic happens below the surface.

Now is the ideal time for sowing these cold-season plants. I’ve chosen forage rye, great for clay soil, a nitrogen-lifter, vetch, and field beans.

There’s satisfaction in planting seeds knowing it’s temporary – at least above ground.
