Want to give your soil some TLC? Plant green manure in your garden and you’ll improve your yields.

Just the other day, I discovered a partially finished bottle of an energy drink left behind in the euphorbia trough by one of the scaffolders. An architect friend joked, “Are you sure that’s Lucozade?” giving me a new perspective.

In short, the garden is in disarray. But there’s a lot to be said for negligence; coming back from a trip, I spotted a sunflower growing in the back corner.

Now, however, some necessary firefighting is underway. As I’m expecting a baby, I’ve enlisted a local gardener to remove troublesome weeds like green alkanet and young tree shoots from the neighbour’s tree, but keeping desirable plants. Next, in the newly cleared patches, I’ll be sowing green manure.

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

My gardening friend Claire has previously discussed cover crops, as they are essential in crop rotation for vegetable plots. However, the only things I’m picking 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 agree with replacing them.

Green manure are like superheroes for your garden’s foundation. Bare soil invites weeds, which is why weeds appear. But by sowing fast-growing plants, you can control weeds, attract pollinators, host pest-eating creatures, and fix nitrogen.

Green manure plants may not look exciting – though some, like certain lupin varieties 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, chop them for mulch, or let them decompose for earthworms to pull down. Their work happens underground.

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

It feels rewarding in planting seeds that won’t stay forever – at least above ground.
