Does your garden soil need a boost? Sow cover crops in your garden and you’ll improve your yields.
I recently found a partially finished bottle of an energy drink left behind 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.
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 professional gardener to tackle troublesome weeds like green alkanet and robinia saplings from the neighbour’s tree, but keeping desirable plants. Then, in the open patches, I’ll be sowing cover crops.
Green manure are superheroes when it comes to boosting soil quality.
A fellow garden writer has previously discussed green manure, as they are essential in crop rotation for vegetable plots. However, the only things I’m harvesting from my garden right now are a few scrumped apples and some hardy herbs.
My garden goals are modest and consistent – and improving the soil is my main priority. To update concerned readers, the scaffolding 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 soil health. Soil likes to be covered, which is why unwanted plants pop up. But by sowing vigorous crops, you can control weeds, bring in bees, shelter beneficial insects, and fix nitrogen.
Green manure plants aren’t always showy – though some, like certain lupin varieties and a flowering legume, have pretty flowers – but their purpose is to grow vigorously rather than look decorative. Once established, you can turn them under, chop them for mulch, or let them decompose for earthworms to incorporate. The real magic happens underground.
Autumn is perfect for sowing these overwintering crops. I’ve chosen forage rye, great for clay soil, Italian ryegrass, vetch, and beans that aerate soil.
It feels rewarding in sowing something knowing it’s temporary – at least above ground.
