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

Just the other day, I discovered a partially finished bottle of an energy drink placed in the euphorbia trough by one of the scaffolders. An architect friend commented, “Are you sure that’s Lucozade?” giving me a new perspective.

In short, the garden is in disarray. But there’s a lot to be said for negligence; after returning from holiday, I spotted a sunflower sprouting in the back corner.

This week, though, some urgent tidying is underway. Being six months pregnant, I’ve enlisted a local gardener to remove troublesome weeds like green alkanet and robinia saplings from the neighbour’s tree, while leaving the good stuff. Then, in the open patches, I’ll be sowing cover crops.

Green manure are superheroes 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 edible gardens. 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 scaffold 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 unwanted plants pop up. Yet by sowing vigorous crops, you can control weeds, attract pollinators, shelter beneficial insects, and enrich the soil with nutrients.

Cover crops may not look exciting – though some, like lupins ‘Blue Sonet’ and bird’s foot trefoil, have pretty flowers – but their role is to thrive rather than look decorative. Once established, you can turn them under, cut them for compost, or let them decompose for earthworms to incorporate. Their work happens below the surface.

Now is the ideal time for sowing these cold-season plants. My selection includes rye grass, great for clay soil, Italian ryegrass, vetch, and field beans.

It feels rewarding in planting seeds knowing it’s temporary – at least above ground.
