How to lay a living mulch with low-growing herbs and why your soil life will thank you
Eleanor AshfordEmbracing the Concept of Living Mulch
Living mulch is, in essence, a mat of low-growing plants that create a protective layer over the soil. This technique harks back to the agricultural practices of old, where nature's way was to be mimicked and revered. Our modern gardens, so often stripped to bare soil or dressed with manufactured mulches, can reclaim this wisdom. By planting living mulch, you help retain moisture, suppress weeds, and create habitats for beneficial organisms and pollinators—a symbiotic relationship steeped in simplicity yet brimming with ecological benefits.
Selecting the Right Herbs
When choosing herbs for your living mulch, consider both their practicality and beauty. Ideally, we seek plants that are hardy, spread willingly but not invasively, and contribute their own unique charm to the garden. Thyme is a splendid candidate. With its fragrant leaves and pretty blooms, it provides the perfect mat of green. Incidentally, I have fond memories of my grandmother's thyme border, a favourite haunt of hers, and eventually of mine too. She would say it was akin to brushing past a perfumed hem, an apt description for the gentle aroma released at a mere touch.
Then there's chamomile, a darling of the garden not just for its calming properties but also for its charming visage. It bears white daisy-like flowers, which invite bees to dance upon them, making it both practical and pleasing. Clover, although often misunderstood, warrants our attention as well. Diminutive yet determined, it fixes nitrogen, enriching the soil, and its soft blossoms serve as a buffet for pollinators.
Planting Your Herbaceous Ground Cover
The establishment phase requires a dash of patience and a smattering of good preparation. Begin by selecting a section of your garden where these herbs will take up residence. A plot with decent sunlight and well-drained soil is optimal. Lightly disturb the soil surface to create a welcoming bed, but take care not to unearth too much, lest you disturb the neighbourhood of soil dwellers already hard at work.
Plant your herbs either as seeds or small transplants in staggered rows or patches, allowing them sufficient space to flourish. Water gently at first, and mulch sparingly between the young plants until they begin to spread on their own. Once established, your living mulch will work industriously, conserving soil moisture and outcompeting the dreaded weeds, freeing you to enjoy more of the garden's many delights.
Nurturing the Soil Beneath
As your herbs spread their tendrils across the earth, beneath them a lively commune of decomposers, fungi, and other denizens will thrive. This living mulch acts as a canopy for these tiny residents, much like how a forest floor shelters its inhabitants. In return, they break down organic matter, bolster the soil's fertility, and foster a network of life that supports the plants above.
Indeed, improving soil structure is one of those marvellous acts of nature that we can assist with minimal effort. The roots of your living mulch will penetrate the soil, creating channels that improve aeration and water infiltration. It’s a wonder that something as unassuming as thyme or chamomile could wield such influence, subtly orchestrating a symphony below ground to the benefit of the entire garden.
Balancing Biodiversity
Adding herbs as a living mulch isn’t merely about the earthly delights of our own plots but also contributes positively to the larger tapestry of biodiversity. By choosing a mixture of herbs and allowing them to flower, you provide sustenance to a variety of pollinators, from bees to butterflies. Their presence is not only a pleasure to behold but also vital to the health of our plants and by extension, ourselves.
In a country garden such as mine nestled in the corners of Kingswood Green, I've noticed the difference that a living mulch makes. There’s a vibrancy in the air, a quiet cacophony of life that echoes the best parts of a bustling village square. Frogs take comfortable refuge beneath leaves, birds cheerily dart in search of titbits, and insects busily flit from blossom to blossom, spreading joy in their wake.
Living Mulch in the Larger Context
Incorporating living mulch into your gardening practice is a pledge to work with nature rather than attempt to subdue it. This shift isn’t just about what your own garden can achieve but signifies a broader commitment to sustainability and ecological mindfulness. So often, we hear about climate change at a global scale, yet it is in our personal domains that we find real agency.
By nurturing our little patches with living mulch, we reduce runoff, improve soil health, and diminish the need for chemical interventions, all whilst supporting an abundance of life. It’s a practical triumph as much as an ethical one, balancing human needs with those of the environment. I would say that’s a rather fine legacy to nurture, not only for ourselves but for future generations basking in the shade of our wisdom.
Reflecting on the Journey
And so, as you embark on the creation of your living mulch, welcome it as a meditation of sorts, each touch of the soil, each new sprout another marker along your journey. There’s something deeply fulfilling about nurturing life that, in turn, nurtures the earth itself. As we gardeners tread this path together, we share not only our harvests but also the quiet satisfaction of knowing that our gardens are as enriching to the planet as they are to our souls.
Mind you, should you find yourself sitting among this herbaceous medley with a cup of freshly brewed chamomile tea in hand, contemplating the morning sun filtering through thyme-scented air, know that you're part of an enduring tradition that honours both past and future. That openness towards shared understanding and respect is what truly roots us to this grand, green world. As always, happy gardening, my dear readers.
