Can bark mulch protect plant roots

Plant roots are far more delicate than they appear, and protecting them from extremes of weather is an important part of keeping a garden healthy. Bark mulch provides a natural shield, offering both insulation and moisture control. By spreading a layer over the soil, roots are buffered from sudden changes in temperature, whether that’s a scorching day in midsummer or a sharp frost in winter.

Moisture retention is another key benefit. Roots need consistent access to water, and bare soil can dry out very quickly, leaving plants struggling. A covering of bark slows evaporation, meaning the soil remains damp for longer and roots are less likely to experience stress. At the same time, mulch reduces surface runoff during heavy rain, giving water more time to soak into the ground.

There is also the matter of physical protection. Bark mulch prevents the soil from becoming compacted by rainfall or foot traffic, which in turn keeps the root zone better aerated and easier for roots to expand through. Over the seasons, as bark breaks down, it adds organic matter that further enhances the growing environment.
