They have removed very large trees and a very large stump for us..  They clean up beautifully and place mats in our yard to use for their equipment and protect our grass.  We will certainly use them again for any tree service we need done.

They have saved several of my large oak trees from the leaf scorch that has been plaguing the oaks.  Also sprayed and saved a number of my evergreens.

 Trustindex verifies that the original source of the review is Google. Joe comes out every year to inspect the trees on my 2 acre property.  Joe recommended a treatment for one of my Ash trees several years ago, and it has saved the tree!  I think these guys are fantastic, and I highly recommend them if you want to keep your trees healthy.  My motto is tree treatment is a lot less expensive than tree removal, so I try to treat and keep them healthy with Keystone Tree Expert's help.

 Trustindex verifies that the original source of the review is Google. I have been taking care of my property for 30 years.  My house is 2 yards from a very busy road so my trees and shrubs are critical to both privacy and safety.  My friends tease me that I have a garden with a house on it.  I have seen my share of arborists come and go.  After feeling bamboozled more than once, this time I conducted a thorough search and interview process, comparing assessments and pricing of about 5 companies.  Keystone did not try to sell me services I did not need, they showed me issues the others missed and their pricing was the best.  They have been no nonsense and are showing me, not telling me, that they are truly experts.

Tree & Shrub Care Services for Horsham, PA

At Keystone, our tree care service plans in Horsham are developed around site-specific needs such as soil composition, moisture levels, species characteristics, and environmental pressures unique to the area.

Plant Health Care Programs

Our PHC programs involve scheduled monitoring to identify early shifts in plant condition that usually precede visible canopy decline. During visits, arborists evaluate leaf quality, twig growth, pest presence, and soil factors to determine whether treatment is warranted.

Each program is built around the species on your property, ensuring interventions are timed and calibrated to provide meaningful benefit rather than unnecessary applications.

Insect & Disease Control

Pests and pathogens disrupt water movement, damage leaf tissue, and weaken structural development when left unmanaged. Effective control requires determining the exact organism involved and applying treatment during its most vulnerable stage.

Our arborists examine affected areas carefully and select targeted control options that focus on halting active damage.

Fertilizing

Trees in suburban settings frequently contend with compacted or nutrient-impoverished soils that restrict natural growth. Deep root fertilization addresses these issues by delivering nutrients directly into the root zone where they can be absorbed efficiently.

Small Tree Pruning

Pruning younger trees requires careful assessment of branch arrangement, structure, and future growth direction. Our arborists remove limbs that create mechanical stress or poorly distributed canopy weight, helping the tree develop a stable framework as it matures.

Consulting

Property planning benefits from knowledgeable guidance, especially when trees interact with construction, utilities, or new landscape installations. Our arborists provide consulting that outline preservation strategies, risk considerations, and long-term management needs.

Tree & Shrub Issues Common in Horsham

Several recurring insects and diseases influence tree health in this part of Montgomery County:

Emerald Ash Borer: A destructive invasive insect affecting ash species.
