Living mulch plants are an underrated gardening technique that offers a multitude of benefits, from water conservation to weed suppression and soil enrichment. These plants, often flowering groundcover varieties or nitrogen-fixing annuals, act as a natural mulch, providing a protective layer around the base of other plants. Julian Palphramand, head of plants at British Garden Centres, emphasizes their practicality, stating that these plants reduce the need for traditional mulch materials like bark or compost. They achieve this by locking in moisture, keeping roots cooler in summer, and effectively suppressing weeds.
One of the most appealing aspects of living mulch is its aesthetic appeal. Plants like Aubrieta, with its vivid purple blooms, add a pop of color to any garden. In my opinion, the Aubrieta 'Purple Cascade' F1 from Thompson & Morgan is a standout choice, offering both beauty and functionality. For those seeking a more natural look, Creeping Thyme provides a low, walk-on carpet that holds moisture and keeps the soil cool. It's a versatile option, especially for sunny, dry spots.
Clover, a popular green manure plant, is another excellent addition to the living mulch family. Garden designer Zoe Claymore recommends sowing clover after a heatwave and rain to maximize its nitrogen-fixing benefits. This plant not only enriches the soil but also spreads quickly, forming a dense, weed-suppressing mat. For those looking to prepare their soil for the next growing season, green manure seeds from Thompson & Morgan are a great investment.
Nasturtiums, with their trailing stems and large leaves, create a weed-suppressing canopy, shading the soil and retaining moisture. Horticultural expert Richard Barker suggests planting them around plants with deep root systems to avoid competition for nutrients. Additionally, nasturtiums offer a wide selection of benefits, making them a versatile choice for any garden.
Lastly, Periwinkle, particularly Vinca minor, is an excellent groundcover plant for shade or areas under trees. It establishes quickly and fills gaps, making it a reliable choice for year-round soil coverage. Crocus offers both 9cm and 2-litre pots of Vinca minor 'Bowles's Variety', ensuring you can find the perfect fit for your garden.
In conclusion, living mulch plants are a game-changer for gardeners seeking a more sustainable and aesthetically pleasing approach. They provide a natural, low-maintenance solution to common gardening challenges, making them an essential tool for any green-thumb enthusiast.
