3 Tips for Composting and Mulching For the Winter


Did you know that mulched soil stays warmer in winter than bare soil? Roots are protected from temperature extremes and creates less freezing and thawing of soil in winter that may injure trees. Temperature changes can lead to stresses within the tree between the outer bark and inner wood which leads to cracks. When applying mulch, follow these tips to make sure your trees stay healthy all winter long:
  1. For well-drained sites, apply a 2-4” inch layer of mulch – add less if poorly drained.  When applying mulch, put it on the edge of a tree’s crown or beyond since its roots stretch well beyond the drip line.
 
  1. Make sure that the bottom of the tree truck is exposed and about 4 to 6 inches away from the trunk when applying the mulch. This ensures that the wet mulch doesn’t come into contact with plant tissue that creates a welcoming environment for disease and pest problems.
 
  1. When choosing a type of mulch, avoid fine, non-composted wood chips because soil nitrogen may be taken up by the roots as the wood chips decompose. Composted wood chips make good mulch, especially when they include bark and leaves. It breaks down a lot faster, but needs to be reapplied more frequently than wood-chip mulch.
Mulching also prevents the evaporation of water from the soil so less watering is required. Using mulch is much decorative as it is protective. Need help with Denver winter tree care?
