Does bark mulch last through winter

Bark mulch is often applied in spring or autumn, but many gardeners wonder how well it holds up once winter arrives. The good news is that bark mulch is more than capable of lasting through the colder months, continuing to provide protection even in challenging conditions.

During winter, the mulch layer acts as an insulating blanket over the soil, keeping roots shielded from sharp frosts and slowing down the freezing and thawing cycle that can damage plants. The mulch itself does not break down quickly in cold weather, as low temperatures slow the activity of fungi and microbes responsible for decomposition. This means the bulk of the mulch remains intact until the following season.

Heavy rain, snow or strong winds may cause some displacement, particularly on sloping ground, but a well-applied layer will generally stay in place. By spring, the mulch may have thinned slightly, and topping up will restore it to full effect. The gradual decomposition that does occur is beneficial, as it adds organic matter back into the soil.
