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 commented, “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 sprouting in the back corner.
Now, however, some necessary firefighting is underway. Being six months pregnant, I’ve enlisted a professional gardener to tackle invasive plants like green alkanet and young tree shoots from the neighbour’s tree, but keeping desirable plants. Next, in the open patches, I’ll be sowing green manure.
Cover crops act like heroes 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 vegetable plots. However, the only things I’m harvesting from my garden right now are a few foraged apples and some hardy herbs.
My ambitions for the garden are modest and consistent – and improving the soil is my main priority. To update concerned readers, the scaffolding is for roof repairs, and the fences are still wobbly, but the neighbours are on board with the plan.
Cover crops are like superheroes for soil health. Soil likes to be covered, which is why unwanted plants pop up. Yet by sowing fast-growing plants, you can control weeds, bring in bees, host pest-eating creatures, and enrich the soil with nutrients.
Green manure plants may not look exciting – though some, like certain lupin varieties and bird’s foot trefoil, have pretty flowers – but their role is to thrive rather than look decorative. After they’ve grown, you can dig them into the soil, cut them for compost, or let them decompose for earthworms to incorporate. Their work happens underground.
Now is the ideal time for sowing these overwintering crops. I’ve chosen forage rye, great for clay soil, a nitrogen-lifter, vetch, and beans that aerate soil.
There’s satisfaction in sowing something that won’t stay forever – on the surface, anyway.
