Does your garden soil need a boost? 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 joked, “Are you sure that’s Lucozade?” giving me a new perspective.

All this is to say, the garden is a bit of a mess. Sometimes neglect has its perks; after returning from holiday, I spotted a sunflower growing in the back corner.

This week, though, some urgent tidying is underway. Being six months pregnant, I’ve enlisted a local gardener to tackle troublesome weeds like a prickly weed 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.

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

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 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 enhancing soil health is top of the list. For those wondering, the scaffolding is for roof repairs, and the fences are yet to be fixed, but the neighbours are on board with the plan.

Cover crops are like superheroes for soil health. Bare soil invites weeds, which is why unwanted plants pop up. But by sowing vigorous crops, you can control weeds, attract pollinators, host pest-eating creatures, and fix nitrogen.

Cover crops aren’t always showy – though some, like certain lupin varieties and bird’s foot trefoil, have lovely blooms – but their role is to grow vigorously rather than look decorative. Once established, you can turn them under, chop them for mulch, or let them decompose for earthworms to pull down. Their work happens below the surface.

Now is the ideal time for sowing these cold-season plants. My selection includes 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 – on the surface, anyway.
