Does your garden soil need a boost? Sow green manure in your garden and you’ll reap the benefits.
I recently found 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. Sometimes neglect has its perks; after returning from holiday, I spotted a sunflower growing in the back corner.
This week, though, some urgent tidying 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. Next, in the open patches, I’ll be sowing green manure.
Cover crops act like heroes when it comes to improving soil health.
A fellow garden writer has previously discussed cover crops, as they play a key role in seasonal planting 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 ambitions for the garden are modest and consistent – and improving the soil is top of the list. To update concerned readers, the scaffold is for roof repairs, and the garden boundaries are still wobbly, but the neighbours are on board with the plan.
Green manure work wonders for soil health. Bare soil invites weeds, which is why unwanted plants pop up. Yet by sowing vigorous crops, you can suppress weeds, bring in bees, shelter beneficial insects, and fix nitrogen.
Cover crops aren’t always showy – though some, like lupins ‘Blue Sonet’ and bird’s foot trefoil, have lovely blooms – but their role is to grow vigorously rather than look decorative. Once established, you can dig them into the soil, chop them for mulch, or leave them on the surface for earthworms to pull down. Their work happens underground.
Autumn is perfect for sowing these overwintering crops. I’ve chosen forage rye, great for clay soil, Italian ryegrass, a weed-suppressor, and field beans.
There’s satisfaction in sowing something that won’t stay forever – at least above ground.
