Just the other day, I discovered a partially finished 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?” giving me a new perspective. 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 growing in the back corner. This week, though, some urgent tidying is underway. Being six months pregnant, I’ve hired a local gardener to tackle invasive plants like green alkanet and robinia saplings from the neighbour’s tree, but keeping desirable plants. Next, in the open patches, I’ll be sowing cover crops. Green manure are superheroes when it comes to improving soil health. A fellow garden writer has written about green manure, as they play a key role in seasonal planting for vegetable plots. But, the only things I’m harvesting 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 garden boundaries are yet to be fixed, but the neighbours are on board with the plan. Cover crops work wonders for your garden’s foundation. Bare soil invites weeds, which is why weeds appear. But by sowing vigorous crops, you can control weeds, bring in bees, host pest-eating creatures, and enrich the soil with nutrients. Green manure plants aren’t always showy – though some, like lupins ‘Blue Sonet’ and bird’s foot trefoil, have lovely blooms – but their role is to thrive rather than look decorative. After they’ve grown, you can dig them into the soil, chop them for mulch, or let them decompose for worms to pull down. Their work happens below the surface. Autumn is perfect for sowing these cold-season plants. My selection includes forage rye, which breaks up heavy earth, a nitrogen-lifter, vetch, and beans that aerate soil. It feels rewarding in sowing something knowing it’s temporary – on the surface, anyway.
