Does your garden soil need a boost? Sow cover crops in your garden and you’ll reap the benefits.

I recently found a partially finished bottle of an energy drink 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.

In short, the garden is a bit of a mess. But there’s a lot to be said for negligence; after returning from holiday, I spotted a sunflower sprouting in the back corner.

Now, however, some urgent tidying is underway. As I’m expecting a baby, I’ve hired a local gardener to tackle troublesome weeds like green alkanet 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 boosting soil quality.

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

My garden goals 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 replacing them.

Green manure are like superheroes 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 fix nitrogen.

Cover crops may not look exciting – though some, like certain lupin varieties and bird’s foot trefoil, have pretty flowers – but their role is to grow vigorously rather than be admired. After they’ve grown, you can turn them under, cut them for compost, or leave them on the surface for earthworms to incorporate. Their work happens below the surface.

Now is the ideal time for sowing these overwintering crops. I’ve chosen rye grass, great for clay soil, a nitrogen-lifter, a weed-suppressor, and field beans.

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