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

Just the other day, I discovered a partially finished bottle of Lucozade left behind in the euphorbia trough by one of the scaffolders. An architect friend joked, “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; after returning from holiday, I spotted a sunflower growing in the back corner.

This week, though, some necessary firefighting is underway. Being six months pregnant, I’ve enlisted a local gardener to remove invasive plants like green alkanet and young tree shoots from the neighbour’s tree, but keeping desirable plants. Next, in the open patches, I’ll be sowing cover crops.

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

My gardening friend Claire 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 garden goals are simple and steady – and enhancing soil health is top of the list. To update concerned readers, the scaffold is for roof repairs, and the fences are still wobbly, but the neighbours agree with replacing them.

Cover crops are like superheroes for your garden’s foundation. Bare soil invites weeds, which is why weeds appear. But by sowing vigorous crops, you can suppress weeds, bring in bees, host pest-eating creatures, and enrich the soil with nutrients.

Green manure plants aren’t always showy – though some, like certain lupin varieties and a flowering legume, have lovely blooms – but their purpose is to grow vigorously rather than be admired. After they’ve grown, you can dig them into the soil, chop them for mulch, or let them decompose for worms to incorporate. Their work happens underground.

Autumn is perfect for sowing these cold-season plants. My selection includes rye grass, which breaks up heavy earth, Italian ryegrass, vetch, and beans that aerate soil.

There’s satisfaction in sowing something knowing it’s temporary – at least above ground.
