Want to give your soil some TLC? Sow 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.

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.

Now, however, some necessary firefighting is underway. As I’m expecting a baby, I’ve enlisted a professional gardener to remove invasive plants like green alkanet and robinia saplings from the neighbour’s tree, but keeping desirable plants. Next, in the newly cleared patches, I’ll be sowing green manure.

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 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 simple and steady – and improving the soil is top of the list. To update concerned readers, the scaffolding is for roof repairs, and the fences are yet to be fixed, but the neighbours agree 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 fix nitrogen.

Green manure plants may not look exciting – though some, like lupins ‘Blue Sonet’ and a flowering legume, have pretty flowers – but their purpose is to grow vigorously rather than be admired. Once established, you can turn them under, chop them for mulch, or let them decompose for earthworms to pull down. The real magic happens underground.

Autumn is perfect for sowing these cold-season plants. I’ve chosen rye grass, great for clay soil, a nitrogen-lifter, a weed-suppressor, and beans that aerate soil.

There’s satisfaction in planting seeds that won’t stay forever – at least above ground.
