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

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

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 enlisted a professional gardener to tackle 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 green manure.

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

My gardening friend Claire has previously discussed green manure, as they play a key role in crop rotation for vegetable plots. But, the only things I’m harvesting from my garden right now are a few scrumped apples and some hardy herbs.

My garden goals are simple and steady – and enhancing soil health is my main priority. For those wondering, the scaffold is for roof repairs, and the fences are still wobbly, but the neighbours agree with the plan.

Green manure work wonders for soil health. Soil likes to be covered, 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.

Cover crops aren’t always showy – though some, like certain lupin varieties and bird’s foot trefoil, have lovely blooms – but their purpose is to grow vigorously rather than look decorative. After they’ve grown, you can turn them under, cut them for compost, or leave them on the surface for worms to pull down. Their work happens underground.

Autumn is perfect 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.
