Soil in need of some love? Plant green manure in your garden and you’ll improve your yields.

Just the other day, I discovered a half-empty bottle of an energy drink placed in the euphorbia trough by one of the scaffolders. A visiting architect 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 growing in the back corner.

This week, though, some necessary firefighting 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. Then, in the newly cleared patches, I’ll be sowing cover crops.

Cover crops act like heroes when it comes to improving soil health.

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

My garden goals are modest and consistent – and enhancing soil health is my main priority. To update concerned readers, the scaffold is for roof repairs, and the fences are still wobbly, but the neighbours agree with replacing them.

Green manure work wonders for your garden’s foundation. Bare soil invites weeds, which is why unwanted plants pop up. But by sowing fast-growing plants, you can suppress weeds, bring in bees, host pest-eating creatures, and fix nitrogen.

Green manure plants may not look exciting – though some, like lupins ‘Blue Sonet’ and bird’s foot trefoil, have pretty flowers – but their purpose is to thrive rather than look decorative. After they’ve grown, you can turn them under, cut them for compost, or let them decompose for worms to pull down. Their work happens below the surface.

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

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