Does your garden soil need a boost? Sow 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 placed 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. Sometimes neglect has its perks; coming back from a trip, I spotted a sunflower sprouting in the back corner.

This week, though, some necessary firefighting is underway. Being six months pregnant, I’ve hired a local gardener to remove invasive plants like a prickly weed and young tree shoots from the neighbour’s tree, but keeping desirable plants. Next, in the open patches, I’ll be sowing cover crops.

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

My gardening friend Claire has previously discussed cover crops, as they play a key role in seasonal planting for edible gardens. However, the only things I’m harvesting from my garden right now are a few foraged apples and some hardy herbs.

My ambitions for the garden 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 yet to be fixed, but the neighbours are on board with replacing them.

Green manure are like superheroes for your garden’s foundation. Bare soil invites weeds, which is why weeds appear. But by sowing fast-growing plants, you can suppress weeds, bring in bees, host pest-eating creatures, and enrich the soil with nutrients.

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. Once established, you can turn them under, cut them for compost, or let them decompose for earthworms to pull down. The real magic happens underground.

Now is the ideal time for sowing these cold-season plants. My selection includes forage rye, which breaks up heavy earth, a nitrogen-lifter, vetch, and field beans.

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