Does your garden soil need a boost? Sow green manure in your garden and you’ll reap the benefits.

I recently found a half-empty bottle of Lucozade 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.

All this is to say, the garden is in disarray. Sometimes neglect has its perks; coming back from a trip, I spotted a sunflower sprouting in the back corner.

Now, however, some urgent tidying is underway. As I’m expecting a baby, I’ve hired a local gardener to remove invasive plants like green alkanet and robinia saplings from the neighbour’s tree, while leaving the good stuff. Next, in the newly cleared patches, I’ll be sowing cover crops.

Cover crops act like heroes when it comes to boosting soil quality.

A fellow garden writer has previously discussed cover crops, as they play a key role in crop rotation for vegetable plots. But, the only things I’m picking from my garden right now are a few scrumped apples and some woody herbs.

My ambitions for the garden are simple and steady – 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 agree with replacing them.

Green manure are like superheroes for soil health. Soil likes to be covered, which is why weeds appear. Yet by sowing fast-growing plants, you can control weeds, bring in bees, shelter beneficial insects, and fix nitrogen.

Green manure plants may not look exciting – though some, like certain lupin varieties and a flowering legume, have lovely blooms – but their role is to grow vigorously rather than be admired. Once established, you can turn them under, chop them for mulch, or leave them on the surface for worms to pull down. The real magic happens underground.

Now is the ideal time for sowing these overwintering crops. My selection includes rye grass, which breaks up heavy earth, a nitrogen-lifter, a weed-suppressor, and beans that aerate soil.

It feels rewarding in planting seeds that won’t stay forever – at least above ground.
