Soil compaction and lack of nutrients often affect urban trees which can lead to dying branches, off-color leaves, and general tree decline. If these symptoms are caught early, the Certified Plant Heath Care Technicians at Wellnitz Tree Care can usually reverse the decline and rejuvenate the tree’s health. Foot and vehicle traffic compact soil over the years and common landscape management practices strip nutrients. These activities contribute to tree decline. Air spading and vertical mulching are the two techniques we use to reinvigorate old trees.
Air spading is used to alleviate compacted soils around the root zone of the tree. Wellnitz Tree Care uses an Air Spade® which produces a jet of supersonic air traveling at Mach II. This tool breaks apart compacted soils while having no effect on non-porous items like tree roots, pipes, or other buried items. We then add compost back to the soil to reintroduce nutrients that have been stripped away over the years. We have seen great results with this technique, and trees that we would have otherwise removed are looking healthy today!
Vertical mulching serves the same purpose as an Air Spade® but is less intrusive. Wellnitz Tree Care will drill two inch wide holes several inches deep in a grid around your tree. This alleviates soil compaction but to a lesser degree than an Air Spade®. We then fill the holes with compost, creating pockets of natural nutrients.
