Does your garden soil need a boost? Sow cover crops in your garden and you’ll improve your yields.

I recently found a half-empty 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 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.

This week, though, some urgent tidying 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, while leaving the good stuff. Then, in the newly cleared patches, I’ll be sowing green manure.

Green manure are superheroes when it comes to improving soil health.

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 foraged apples and some woody herbs.

My ambitions for the garden are simple and steady – and improving the soil is my main priority. For those wondering, the scaffolding is for roof repairs, and the garden boundaries are yet to be fixed, but the neighbours agree with the plan.

Green manure are like superheroes for your garden’s foundation. Bare soil invites weeds, which is why weeds appear. Yet by sowing vigorous crops, you can suppress weeds, bring in bees, shelter beneficial insects, and enrich the soil with nutrients.

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 be admired. Once established, you can turn them under, chop them for mulch, or leave them on the surface for earthworms to incorporate. The real magic happens below the surface.

Now is the ideal time for sowing these overwintering crops. My selection includes forage rye, which breaks up heavy earth, a nitrogen-lifter, vetch, and field beans.

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