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 half-empty 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 sprouting in the back corner.

Now, however, some urgent tidying is underway. As I’m expecting a baby, I’ve enlisted a professional gardener to tackle troublesome weeds like green alkanet and robinia saplings 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 improving soil health.

A fellow garden writer has previously discussed cover crops, as they play a key role in seasonal planting for vegetable plots. However, the only things I’m picking from my garden right now are a few foraged apples and some woody herbs.

My garden goals are modest and consistent – and enhancing soil health is my main priority. For those wondering, the scaffolding 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. Soil likes to be covered, which is why weeds appear. Yet by sowing vigorous crops, you can control weeds, bring in bees, shelter beneficial insects, and enrich the soil with nutrients.

Cover crops aren’t always showy – though some, like lupins ‘Blue Sonet’ and bird’s foot trefoil, have lovely blooms – but their purpose 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 worms to incorporate. Their work 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 field beans.

It feels rewarding in sowing something knowing it’s temporary – at least above ground.
