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

Just the other day, I discovered a half-empty bottle of Lucozade placed in the euphorbia trough by one of the scaffolders. A visiting architect commented, “Are you sure that’s Lucozade?” giving me a new perspective.

All this is to say, the garden is in disarray. Sometimes neglect has its perks; coming back from a trip, I spotted a sunflower growing in the back corner.

This week, though, some necessary firefighting is underway. Being six months pregnant, I’ve enlisted a professional gardener to remove troublesome weeds like a prickly weed and robinia saplings 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 boosting soil quality.

My gardening friend Claire has previously discussed cover crops, 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 hardy herbs.

My ambitions for the garden are modest and consistent – and improving the soil is my main priority. To update concerned readers, the scaffold is for roof repairs, and the fences are still wobbly, but the neighbours are on board with the plan.

Green manure work wonders for your garden’s foundation. Soil likes to be covered, which is why weeds appear. Yet by sowing fast-growing plants, you can suppress weeds, attract pollinators, host pest-eating creatures, and enrich the soil with nutrients.

Cover crops may not look exciting – though some, like certain lupin varieties and a flowering legume, have lovely blooms – but their role is to thrive rather than be admired. Once established, you can turn them under, chop them for mulch, or leave them on the surface 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 rye grass, great for clay soil, a nitrogen-lifter, vetch, and field beans.

It feels rewarding in sowing something knowing it’s temporary – on the surface, anyway.
