Soil-Injected Deep Root Fertilizer for Trees and Shrub Applied - November 2024

The trees and shrubs have been fed for the year.  Dormant fed.

This is now year five of having the tree care folks from Davey apply a soil-injected deep-root liquid fertilizer (they call it ArborGreenPro) to all of our trees and shrubs on the property.  Here is the post from last year (2023), when they applied the fertilizer in December.  That was later than most years, as the first couple of guys who arrived didn't have long-enough hoses to reach our far backyard.  

Here's the 2022 post from November 9th.  I posted on November 17th in 2021.  And I posted in late October in 2020 - the first year of treatments.  

The dude from Davey uses a long probe, attached to a hose to inject the fertilizer in/around every tree and shrub.  For the larger trees, they inject in a number of sites that line-up to the reach of the canopy of the tree.

Does this stuff work?  I don't really know.  Do you???
