Bark Mulch

Bark mulch, derived from the outer layers of trees, serves as an invaluable asset in British gardening. When applied to garden beds, it acts as a protective blanket, helping to suppress weed growth by limiting sunlight exposure to the soil, thereby reducing the emergence of unwanted plants. This natural barrier not only minimises the need for chemical weed control but also aids in retaining soil moisture, as it slows down evaporation, ensuring that plants have a consistent water supply.

The insulating properties of bark mulch are particularly beneficial in the UK’s variable climate. By moderating soil temperatures, it keeps roots cooler during hot spells and warmer during frosty periods, thus promoting healthier plant growth. As the mulch gradually decomposes, it enriches the soil with organic matter, enhancing its structure and fertility. This decomposition process fosters a thriving ecosystem of beneficial microorganisms and earthworms, which further contribute to soil health.

Aesthetically, bark mulch offers a tidy and cohesive appearance, complementing various garden designs with its natural texture and colour. To maximise its benefits, it’s advisable to apply a layer approximately 5 to 7.5 centimetres deep, taking care to keep it away from the base of plants to prevent potential rot. Regular replenishment every couple of years will maintain its effectiveness and visual appeal. Incorporating bark mulch into your gardening routine not only enhances the beauty of your outdoor space but also supports a healthier and more resilient garden ecosystem.
