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

I recently found a partially finished bottle of Lucozade placed in the euphorbia trough by one of the scaffolders. An architect friend joked, “Are you sure that’s Lucozade?” which made me see it differently.

All this is to say, the garden is a bit of a mess. But there’s a lot to be said for negligence; coming back from a trip, I spotted a sunflower sprouting in the back corner.

This week, though, some necessary firefighting is underway. As I’m expecting a baby, I’ve hired a local gardener to tackle invasive plants like a prickly weed and young tree shoots from the neighbour’s tree, while leaving the good stuff. Next, in the open patches, I’ll be sowing cover crops.

Green manure are superheroes when it comes to improving soil health.

My gardening friend Claire has written about green manure, 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 top of the list. To update concerned readers, the scaffold is for roof repairs, and the garden boundaries are still wobbly, but the neighbours agree with replacing them.

Cover crops are like superheroes for your garden’s foundation. Soil likes to be covered, which is why unwanted plants pop up. But by sowing vigorous crops, you can suppress weeds, attract pollinators, host pest-eating creatures, and fix nitrogen.

Cover crops may not look exciting – though some, like lupins ‘Blue Sonet’ and bird’s foot trefoil, have pretty flowers – but their purpose is to grow vigorously rather than look decorative. Once established, you can dig them into the soil, cut them for compost, or leave them on the surface for earthworms to incorporate. The real magic happens underground.

Now is the ideal time for sowing these overwintering crops. I’ve chosen rye grass, which breaks up heavy earth, Italian ryegrass, vetch, and beans that aerate soil.

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