Want to give your soil some TLC? Plant green manure in your garden and you’ll reap the benefits.

Just the other day, I discovered a half-empty bottle of an energy drink left behind in the euphorbia trough by one of the scaffolders. A visiting architect joked, “Are you sure that’s Lucozade?” which made me see it differently.

All this is to say, 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 necessary firefighting is underway. As I’m expecting a baby, I’ve enlisted a professional gardener to tackle troublesome weeds like a prickly weed and young tree shoots from the neighbour’s tree, but keeping desirable plants. Then, in the newly cleared 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 green manure, as they are essential in seasonal planting for vegetable plots. However, 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 improving the soil is top of the list. For those wondering, the scaffolding is for roof repairs, and the fences are yet to be fixed, but the neighbours are on board with replacing them.

Green manure work wonders for your garden’s foundation. Soil likes to be covered, 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.

Green manure plants aren’t always showy – though some, like lupins ‘Blue Sonet’ and a flowering legume, have pretty flowers – but their purpose is to grow vigorously rather than look decorative. After they’ve grown, you can turn them under, cut them for compost, or let them decompose for earthworms to pull down. The real magic happens below the surface.

Now is the ideal time for sowing these cold-season plants. I’ve chosen rye grass, which breaks up heavy earth, a nitrogen-lifter, a weed-suppressor, and beans that aerate soil.

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