The Power of Wood Bark in Winter
Winter can be tough on plants and soil, with freezing temperatures, frost heaving, and moisture loss posing serious challenges for landscapers. That’s where wood bark and mulch come in. Acting as natural insulators, they help protect plant roots, regulate soil temperature, and reduce evaporation. Whether you’re prepping large commercial landscapes or smaller garden projects, winterizing with wood bark is a must for preserving soil health and plant vitality.
In this blog, we’ll share why wood bark is your best friend during the colder months and how to use it effectively for winter protection.
Why winterize with wood bark and mulch?
Insulates and protects roots
Wood bark acts like a cosy blanket for plant roots, insulating them from fluctuating temperatures and reducing the risk of frost damage.Prevents frost heaving
By keeping soil temperatures more consistent, bark reduces the chance of frost heaving, which occurs when soil freezes, expands, and forces plant roots upward.Locks in soil moisture
Cold winter winds and frost can sap moisture from the soil. Wood bark helps trap that moisture, keeping roots hydrated even in drier, colder conditions.Suppresses weeds
Mulching isn’t just for summer – wood bark suppresses winter weed growth too, saving you time and effort when spring rolls around.
How to apply wood bark for winter protection
Clear and prepare the area
Remove fallen leaves, debris, and weeds to prevent pests and diseases from overwintering.Apply a 2–4-inch layer
Spread bark evenly around plant bases, keeping it a few inches away from stems to avoid rot. For larger areas, 1 cubic meter of bark can cover approximately 20 square meters at a 5 cm depth.Choose the right bark
Coarser bark, such as chunky wood bark, is ideal for insulation, while finer mulch works well for moisture retention in flower beds.
