Does bark mulch keep roots cool

Bark mulch is often praised for its ability to moderate soil temperature, and one of its most useful benefits is keeping plant roots cool during warmer weather. When the sun beats down on bare soil, it quickly heats up, causing moisture to evaporate and putting stress on roots just below the surface. A layer of bark mulch acts like insulation, shielding the ground from direct sunlight and helping to maintain a steadier temperature.

This cooling effect is particularly helpful for shallow-rooted plants and young specimens that are more sensitive to fluctuations. By reducing the impact of heat, bark mulch lessens the strain on roots, helping plants to remain hydrated and stable even in dry spells. It also prevents soil from cracking or hardening, both of which can expose roots to further stress.

Over time, as bark mulch begins to decompose, it continues to enrich the soil, supporting better structure and moisture retention. AHS LTD offers bark mulches suitable for this very purpose, providing both functional and visual benefits in one simple step. Using bark mulch around plants not only improves the look of a garden but also creates a more comfortable, balanced environment for roots to grow strong and healthy.
