Soil in need of some love? Sow cover crops in your garden and you’ll reap the benefits.

I recently found a partially finished bottle of Lucozade left behind in the euphorbia trough by one of the scaffolders. A visiting architect commented, “Are you sure that’s Lucozade?” which made me see it differently.

In short, the garden is in disarray. Sometimes neglect has its perks; coming back from a trip, I spotted a sunflower growing in the back corner.

Now, however, some urgent tidying is underway. Being six months pregnant, I’ve hired 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 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 green manure, 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 hardy herbs.

My garden goals 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 garden boundaries are yet to be fixed, but the neighbours are on board with replacing them.

Green manure work wonders for soil health. Bare soil invites weeds, which is why weeds appear. But by sowing fast-growing plants, you can control weeds, bring in bees, shelter beneficial insects, and fix nitrogen.

Cover crops may not look exciting – though some, like lupins ‘Blue Sonet’ and bird’s foot trefoil, have lovely blooms – but their role is to grow vigorously rather than look decorative. Once established, you can dig them into the soil, cut them for compost, or let them decompose for earthworms to pull down. Their work happens underground.

Autumn is perfect for sowing these cold-season plants. I’ve chosen rye grass, which breaks up heavy earth, a nitrogen-lifter, a weed-suppressor, and field beans.

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