Annual Liquid Tree and Shrub Fertilizer Application from Davey - November 2021

If you look closely at the photo below, you'll see a hose that is attached to a long three-foot(ish) spike.  That's the tool used by the arborists at Davey who came by recently to fertilize all of our trees and shrubs.  This is the second year that I've feed some of our trees with liquid fertilizer from Davey - last year, however, I feed just the Oaks in back and the troubled Norway Maple in front.  This year, I had them feed EVERYTHING.  Davey uses something called Arbor Green PRO liquid fertilizer.  They inject it into the ground around the drip line of trees and shrubs - and do it late in the year (right now) - when the trees have begun to shed all their leaves.

Here (below) is a look at the description of the slip they dropped on our front door: "Soil injected fertilizer for all trees/shrubs to improve landscape health and vigor."

I went out and looked around at some of the spots where the tech injected the fertilizer and found little holes with soil that appears to have bubbled up from the injection of the tree and shrub food.

Last Winter - about 6 weeks after the application of the liquid fertilizer, I noticed an interesting pattern on the lawn based on where they injected the food.  At the time, I wasn't sure what it was, but now I know it was from Davey's application.  Even by April - almost six months post application - I was still seeing vigorous growth in and around the injection sites.  Kinda interesting to track over time, isn't it?
