Why She Became An Arborist:

“My passion for becoming an Arborist began with an interest and appreciation of the outdoors and nature.  I grew up in Edinburgh, Scotland and began my career at the Royal Botanical Gardens of Edinburgh.  I spent more time outdoors than indoors, and wanted a career that would allow me to continue that passion.  Nobody else was studying plant science, which also appealed to my individualism.”

Customer Service Philosophy:

“Treat my clients how I would like to be treated.”

What are Alison’s Clients Saying?

“Efficient, high quality, professional competence — all at a competitive sum. At first [Alison] Pottage won me over by her solid knowledge as an arborist, then the crew did their job to her specifications on our 60 to 70 foot oaks within a remarkable period of time — and left the grounds quite clean.”
Bob B., Philadelphia, PA
“Keep up the good work! I’m extremely pleased. My lawn was terrible before you took over the job. Now it’s beautiful.”
Andrea K., Bryn Mawr, PA
“I am very happy with the results [of the DeerTech system]. I rarely see a deer, but they are always at the woods edge of my property and don’t appear to venture forward!”
Pat M., Haverford, PA

Observations in the Field:

Boxwood Blight

October 17, 2018 – This devastating disease was recently found in Haverford and can tear through an entire boxwood landscape in a matter of weeks. Infected material should be disposed of carefully (double bagged, and buried) to minimize spread. It’s not recommended to replant with boxwoods as the infection can stay in the soil for up to five years. Boxwood blight sprays can protect a high value boxwood planting if there has been infection in the area.

Lightning Tree Damage

October 3, 2018 – This is a rather extreme example of what lightning is capable of. However, if you have a mature tree of significant (at least 30 inch diameter or greater) within 10 feet of your home, I would consider incorporating a lightning protection system to protect the tree and your house from the potential hazards of a lightning strike.

September 20, 2018 – As we go into fall, new mysterious growths can occur around the base of your tree, around the root collar or on the actual trunk of the tree. Some can be spectacularly large or colorful. However, if mushrooms or fungi appear for the first time around a significant tree, it is best to have it assessed by a professional in case it is indicative of internal or root decay.

Winter Damage

June 26, 2018 – To stake or not to stake? This winter brought a lot of damage due to wind and heavy, wet snow. This caused some trees to be partially uprooted. There are scenarios where we can potentially stabilize and save the tree depending on tree type, degree of lean, amount of root damage and the age of the tree. Sometimes, with the degree of engineering, it may be best to invest in a new tree.

Emerald Ash Borers

June 12, 2018 – Visible signs of Emerald Ash Borer infestation: I noticed these scars or scabs on the trunk of an Ash Tree that is in decline and your first check would be for Emerald Ash Borer. Finding D-shape holes high in the canopy can be challenging, but woodpeckers peeling off the bark to get to the borers is a good indicator of infection.
