Does your garden soil need a boost? Sow green manure in your garden and you’ll reap the benefits.

I recently found a half-empty bottle of Lucozade left behind in the euphorbia trough by one of the scaffolders. An architect friend commented, “Are you sure that’s Lucozade?” which made me see it differently.

In short, 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 necessary firefighting is underway. Being six months pregnant, I’ve hired a professional gardener to tackle invasive plants like green alkanet and young tree shoots from the neighbour’s tree, but keeping desirable plants. Then, in the open 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 seasonal planting for vegetable plots. But, the only things I’m harvesting from my garden right now are a few scrumped apples and some hardy herbs.

My garden goals are simple and steady – and improving the soil is top of the list. For those wondering, the scaffolding is for roof repairs, and the garden boundaries are yet to be fixed, but the neighbours are on board with replacing them.

Green manure are like superheroes for soil health. Bare soil invites weeds, which is why unwanted plants pop up. But by sowing fast-growing plants, you can suppress weeds, bring in bees, shelter beneficial insects, and fix nitrogen.

Cover crops may not look exciting – though some, like lupins ‘Blue Sonet’ and bird’s foot trefoil, have pretty flowers – but their role is to thrive rather than be admired. After they’ve grown, you can dig them into the soil, chop them for mulch, or leave them on the surface for earthworms to incorporate. Their work happens underground.

Autumn is perfect for sowing these overwintering crops. My selection includes forage rye, great for clay soil, Italian ryegrass, a weed-suppressor, and field beans.

It feels rewarding in planting seeds that won’t stay forever – at least above ground.
