canopy alert
BEECH LEAF DISEASE is in your neighborhood
Come on, let's walk the grounds together …
Let’s talk about what we see as we plan for this season and a lifetime from now. Our mission is preserving the beautiful canopy of the Main Line, one precious tree at a time.
Your trees usher in the years with familiarity, consistency and enduring beauty.
Since 1957, we’ve inherited a passion for protecting and maintaining these comforting guardians and the neighborhoods in which they grow.
We are Certified Arborists, working closely with our clients, envisioning and planning future growth. While our field knowledge and experience are second to none, it’s our desire to learn and grow every day, to provide information to guide informed decisions. We are rooted in the belief that cultivating healthy relationships will strengthen the flora we share.
We align with your vision for the property you steward. We walk together.
“This is a special property, but there’s nothing that I need to worry about. From the caring of the tree and the nutrients, to the overall health of the property. The aesthetics are important. When they trim it looks good, not butchered. It looks like it should.”
– G. Frye, Chestnut Hill

A Message From Jim Ward 2026

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.
