Proper mulching is one of the most beneficial practices you can provide for your trees and large shrubs, but selecting the right type of mulch makes all the difference.
Organic mulches such as shredded hardwood, aged wood chips, shredded leaves, and composted bark are excellent choices that break down over time to improve soil structure and provide nutrients.
These materials help retain soil moisture, suppress weeds, and regulate soil temperature while creating an attractive, natural appearance around your plantings.
Avoid fresh wood chips or sawdust, which can temporarily tie up nitrogen as they decompose, and avoid dyed mulches that may contain unknown chemicals.
The key to successful mulching lies not just in material selection, but in proper application technique. Create a mulch ring extending 3-4 feet from the trunk for mature trees, applying a 2-to-4-inch layer while keeping mulch several inches away from the trunk itself—never create the dreaded “volcano” of mulch piled against the bark, which can lead to pest problems, disease, and root girdling. For large shrubs, a 2–3-foot radius with 2 to 3 inches of mulch depth works well. Remember that mulch should complement your landscape’s natural ecosystem, so consider using locally sourced materials when possible.
As we head into fall here in Oneida County, it is an ideal time to refresh mulch around your trees and shrubs before winter arrives.
This seasonal application will help protect root systems from temperature fluctuations and reduce spring maintenance. Your trees and shrubs will reward you with healthier growth, better drought tolerance, and reduced competition from weeds—all while creating a polished look for your landscape that lasts through the seasons.
