 Trustindex verifies that the original source of the review is Google. We have been very happy with the work that Keystone Arborist has done for us.  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.

 Trustindex verifies that the original source of the review is Google. If you need a reliable tree service call Keystone!  They are fast, efficient, and a pleasure to deal with.  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.

Our Tree & Shrub Care Services

At Keystone, our certified arborists provide comprehensive tree and shrub care services in Doylestown, combining proactive programs and specialized treatments to keep your landscape thriving year-round.

Plant Health Care Programs

Our ISA-certified arborists design customized Plant Health Care (PHC) programs that protect trees and shrubs through year-round monitoring and proactive treatments. Regular visits allow us to identify stress, pests, and diseases early, applying treatments only when necessary.

Each plant health care program is customized to the species and soil conditions of your property, supporting long-term health and reducing the need for excessive chemical use.

Insect & Disease Control

Bucks County landscapes are vulnerable to insects like borers, aphids, and scale, along with fungal and bacterial diseases that spread quickly if untreated. Our arborists diagnose these problems at the right stage and apply targeted treatments that stop damage before it threatens tree stability.

This approach to insect and disease control strengthens resilience and preserves tree vigor for years to come.

Fertilizing

Healthy soil is the foundation of healthy trees. Our deep root fertilization process delivers nutrients directly into the root zone, bypassing turfgrass competition and reaching the areas where they’re most effective.

Applied by our certified arborists, this fertilizing method improves root development, increases resistance to pests and drought, and promotes stronger, more vibrant growth throughout your landscape.

Small Tree Pruning

Proper small tree pruning keeps young trees strong, safe, and well-shaped as they mature. Certified arborists carefully remove weak or hazardous limbs while guiding natural growth, reducing future risks and enhancing aesthetics.

Because poor pruning or over-shearing can permanently weaken a plant, our certified professionals ensure every cut supports long-term health.

Consulting

When planning a new installation, protecting trees during construction, or managing a large property, clients meet directly with our arborists for professional consultation. We provide expert guidance on tree selection, protection strategies, and long-term property maintenance.

We also serve as arborist consultants for several Bucks and Montgomery County municipalities, reflecting our role as a trusted authority in the region.
