Vertical Mulching

A Technical Report from The Bartlett Tree Research Laboratories

Vertical mulching (VM) is a technique used to assist in alleviating soil compaction within the critical root zones of trees i.e. area under the canopy. VM is also a means of fertilising trees and encouraging soil biological activity. VM can also reduce damage from excessive water by allowing necessary aeration during wet periods and sub-soil water penetration during dry periods. The technique also aids in promoting the formation of fine feeder roots.
