SPRING 2026
A Message from Jim Ward

As I approach my 40th year taking care of our wonderful clients’ trees I want to reflect on how fortunate we are as a company to be able to care for so many glorious trees and beautiful properties.

Last year, we wrote about how a new disease affecting beech trees made it to our service area. Unfortunately, Beech Leaf Disease has now spread and become established in our area much faster than we expected.

Zone Pushers – Oak Trees from Zones 8-10
ISA Certified Arborist 1072A
USDA Plant Hardiness Zones are based on average annual winter temperatures — specifically, the coldest temperature a plant can withstand. Zones are numbered from 1 (north central Minnesota) to 13 (the Florida Keys). Because of the trend toward milder winters, in 2024 our region was moved from Zone 6 to Zone 7, which is very forgiving and mildly temperate.
English Elms – Ulmus procera
ISA Certified Arborist PD-78
In the 18th and 19th centuries, trees from all over the temperate world were planted, and artfully arranged, on the estates of the British aristocracy. Among them were oaks, maples, Tulip poplars, sassafras, and dogwoods. American trees collected and shipped to England by Philadelphia nurseryman John Bartram.
