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

Just the other day, I discovered a half-empty 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?” which made me see it differently.

All this is to say, the garden is in disarray. But there’s a lot to be said for negligence; after returning from holiday, I spotted a sunflower sprouting in the back corner.

This week, though, 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, while leaving the good stuff. Then, in the newly cleared patches, I’ll be sowing cover crops.

Green manure are superheroes when it comes to boosting soil quality.

My gardening friend Claire has previously discussed green manure, as they are essential in crop rotation for vegetable plots. But, the only things I’m picking from my garden right now are a few foraged apples and some woody herbs.

My ambitions for the garden are simple and steady – and improving the soil is my main priority. For those wondering, the scaffold is for roof repairs, and the garden boundaries are still wobbly, but the neighbours are on board with the plan.

Green manure are like superheroes for soil health. Soil likes to be covered, which is why unwanted plants pop up. But by sowing vigorous crops, you can control weeds, attract pollinators, shelter beneficial insects, and fix nitrogen.

Cover crops aren’t always showy – though some, like lupins ‘Blue Sonet’ and bird’s foot trefoil, have lovely blooms – but their purpose is to grow vigorously rather than be admired. After they’ve grown, you can turn them under, chop them for mulch, or leave them on the surface for worms to incorporate. The real magic happens underground.

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

There’s satisfaction in planting seeds knowing it’s temporary – on the surface, anyway.
