Want to give your soil some TLC? Plant cover crops in your garden and you’ll improve your yields.

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

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

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

Green manure are superheroes when it comes to boosting soil quality.

A fellow garden writer has written about green manure, 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 hardy herbs.

My ambitions for the garden are simple and steady – and improving the soil is top of the list. For those wondering, 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 soil health. Bare soil invites weeds, which is why unwanted plants pop up. But by sowing vigorous crops, you can control weeds, bring in bees, 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 purpose is to grow vigorously rather than be admired. Once established, you can turn them under, cut them for compost, or leave them on the surface for earthworms to incorporate. The real magic happens below the surface.

Autumn is perfect for sowing these overwintering crops. I’ve chosen rye grass, which breaks up heavy earth, Italian ryegrass, a weed-suppressor, and beans that aerate soil.

It feels rewarding in planting seeds knowing it’s temporary – on the surface, anyway.
