As the clearing and replanting got underway at the arboretum this tree began to show signs of renewed vigour and growth. The decision to fell was reconsidered and year on year this tree continued to improve. The reason for the recovery of this tree was fairly simple. Nature had actually decompacted the soil around this tree by physically lifting it in the ground. This allowed increased drainage and aeration, improving soil structure. The mass of microorganisms in the soil increased and roots could grow and function in a much better way.
And so Kew began a program of decompaction around many of their older established trees. Techniques and machinery have evolved since then and Kew now uses both the Air Spade and the Vogt Geo Injector to deliver their tree care program at the arboretum.
At Geo Tree we use the same equipment and products to bring this service to your trees.
The loosened soil was then treated with a suitable mulch of composted wood chip and/or horse manure to ‘feed’ the symbiotic fungi and roots below. Kew Gardens continue to apply these measures to promote the health and longevity of their trees.
