Soil in need of some love? Sow green manure in your garden and you’ll reap the benefits.
Just the other day, I discovered a partially finished bottle of Lucozade placed 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.
All this is to say, the garden is a bit of a mess. Sometimes neglect has its perks; after returning from holiday, I spotted a sunflower sprouting in the back corner.
This week, though, some necessary firefighting is underway. Being six months pregnant, I’ve enlisted a local gardener to remove invasive plants like green alkanet and robinia saplings from the neighbour’s tree, but keeping desirable plants. Then, in the newly cleared patches, I’ll be sowing cover crops.
Green manure are superheroes when it comes to boosting soil quality.
My gardening friend Claire has previously discussed green manure, as they play a key role in crop rotation for edible gardens. But, the only things I’m harvesting from my garden right now are a few scrumped apples and some hardy herbs.
My garden goals are simple and steady – and enhancing soil health is top of the list. For those wondering, the scaffolding is for roof repairs, and the fences are yet to be fixed, but the neighbours are on board with replacing them.
Green manure work wonders for soil health. Soil likes to be covered, 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 may not look exciting – though some, like certain lupin varieties and bird’s foot trefoil, have pretty flowers – but their role is to grow vigorously rather than look decorative. After they’ve grown, you can turn them under, cut them for compost, or let them decompose for worms to incorporate. Their work happens underground.
Autumn is perfect for sowing these overwintering crops. I’ve chosen rye grass, great for clay soil, a nitrogen-lifter, a weed-suppressor, and field beans.
It feels rewarding in planting seeds knowing it’s temporary – on the surface, anyway.
