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

I recently found a partially finished bottle of Lucozade left behind in the euphorbia trough by one of the scaffolders. An architect friend commented, “Are you sure that’s Lucozade?” giving me a new perspective.

All this is to say, the garden is a bit of a mess. But there’s a lot to be said for negligence; coming back from a trip, I spotted a sunflower growing in the back corner.

This week, though, some necessary firefighting is underway. Being six months pregnant, I’ve hired a professional gardener to tackle troublesome weeds like green alkanet and young tree shoots from the neighbour’s tree, but keeping desirable plants. Then, in the newly cleared patches, I’ll be sowing green manure.

Cover crops act like heroes when it comes to boosting soil quality.

My gardening friend Claire has previously discussed green manure, as they play a key role 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 hardy herbs.

My garden goals are modest and consistent – and enhancing soil health is top of the list. For those wondering, the scaffolding is for roof repairs, and the garden boundaries are still wobbly, but the neighbours are on board with the plan.

Cover crops work wonders for your garden’s foundation. Soil likes to be covered, which is why unwanted plants pop up. But by sowing fast-growing plants, you can control weeds, attract pollinators, host pest-eating creatures, and fix nitrogen.

Green manure plants may not look exciting – though some, like certain lupin varieties and a flowering legume, have pretty flowers – but their purpose is to thrive rather than be admired. After they’ve grown, you can turn them under, cut them for compost, or leave them on the surface for earthworms to pull down. Their work happens below the surface.

Autumn is perfect for sowing these overwintering crops. I’ve chosen forage rye, which breaks up heavy earth, Italian ryegrass, vetch, and field beans.

There’s satisfaction in sowing something knowing it’s temporary – at least above ground.
