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 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.

In short, the garden is in disarray. But there’s a lot to be said for negligence; coming back from a trip, I spotted a sunflower growing in the back corner.

Now, however, some necessary firefighting is underway. Being six months pregnant, I’ve hired a local gardener to tackle troublesome weeds like a prickly weed and robinia saplings from the neighbour’s tree, while leaving the good stuff. Then, in the open patches, I’ll be sowing green manure.

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

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

My garden goals are modest and consistent – and improving the soil is my main priority. To update concerned readers, 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 work wonders for soil health. Soil likes to be covered, which is why unwanted plants pop up. Yet by sowing fast-growing plants, you can suppress weeds, attract pollinators, host pest-eating creatures, and enrich the soil with nutrients.

Cover crops aren’t always showy – though some, like certain lupin varieties and bird’s foot trefoil, have pretty flowers – but their purpose is to thrive rather than be admired. Once established, you can turn them under, chop them for mulch, or let them decompose for worms to incorporate. Their work happens underground.

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

It feels rewarding in planting seeds that won’t stay forever – on the surface, anyway.
