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 Lucozade placed 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.

All this is to say, the garden is a bit of a mess. Sometimes neglect has its perks; coming back from a trip, I spotted a sunflower sprouting in the back corner.

This week, though, some necessary firefighting is underway. As I’m expecting a baby, I’ve hired a professional gardener to remove troublesome weeds like green alkanet and young tree shoots from the neighbour’s tree, while leaving the good stuff. Then, 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 written about cover crops, as they play a key role in crop rotation for edible gardens. But, 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 enhancing soil health 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 replacing them.

Cover crops are like superheroes for soil health. Bare soil invites weeds, which is why unwanted plants pop up. Yet by sowing fast-growing plants, you can suppress weeds, bring in bees, host pest-eating creatures, and enrich the soil with nutrients.

Cover crops aren’t always showy – 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. After they’ve grown, you can turn them under, chop them for mulch, or let them decompose for worms to pull down. Their work happens underground.

Now is the ideal time for sowing these cold-season plants. I’ve chosen rye grass, great for clay soil, a nitrogen-lifter, a weed-suppressor, and field beans.

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