Does your garden soil need a boost? Plant green manure in your garden and you’ll enrich your soil.

Just the other day, I discovered a partially finished bottle of an energy drink 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 growing in the back corner.

Now, however, some urgent tidying is underway. Being six months pregnant, I’ve hired a professional gardener to tackle invasive plants like a prickly weed and robinia saplings from the neighbour’s tree, but keeping desirable plants. Then, in the open patches, I’ll be sowing cover crops.

Green manure are superheroes when it comes to improving soil health.

A fellow garden writer has previously discussed cover crops, as they play a key role in crop rotation for edible gardens. But, the only things I’m picking from my garden right now are a few scrumped apples and some hardy herbs.

My garden goals are simple and steady – and enhancing soil health is my main priority. To update concerned readers, the scaffold 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. Yet by sowing fast-growing plants, you can suppress weeds, bring in bees, host pest-eating creatures, and fix nitrogen.

Green manure plants may not look exciting – though some, like certain lupin varieties and bird’s foot trefoil, have lovely blooms – but their purpose is to grow vigorously rather than be admired. After they’ve grown, you can dig them into the soil, chop them for mulch, or let them decompose for worms to pull down. The real magic happens underground.

Autumn is perfect for sowing these overwintering crops. My selection includes forage rye, great for clay soil, a nitrogen-lifter, vetch, and beans that aerate soil.

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