Does your garden soil need a boost? Sow cover crops 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. 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; coming back from a trip, I spotted a sunflower sprouting in the back corner.

Now, however, some urgent tidying is underway. Being six months pregnant, I’ve hired a professional gardener to tackle troublesome weeds like a prickly weed and young tree shoots from the neighbour’s tree, while leaving the good stuff. Next, in the newly cleared patches, I’ll be sowing cover crops.

Cover crops act like heroes when it comes to improving soil health.

A fellow garden writer has written about green manure, as they play a key role in seasonal planting for vegetable plots. However, the only things I’m picking from my garden right now are a few foraged apples and some woody herbs.

My ambitions for the garden are modest and consistent – and enhancing soil health is my main priority. For those wondering, the scaffold is for roof repairs, and the garden boundaries are yet to be fixed, but the neighbours are on board with the plan.

Green manure are like superheroes for soil health. Soil likes to be covered, 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.

Green manure plants may not look exciting – though some, like lupins ‘Blue Sonet’ and bird’s foot trefoil, have pretty flowers – but their purpose 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 pull down. The real magic happens below the surface.

Now is the ideal time for sowing these overwintering crops. I’ve chosen forage rye, which breaks up heavy earth, a nitrogen-lifter, a weed-suppressor, and beans that aerate soil.

It feels rewarding in sowing something knowing it’s temporary – at least above ground.
