Our Services

Keystone offers a wide array of services to residential customers, commercial customers and other green industry professionals. We pride ourselves in educating others about problems that affect trees and shrubs. We routinely work with landscapers to help maintain properties, garden centers to help educate do-it-yourselfers and property owners who recognize the importance of maintaining their trees and shrubs.

Plant Health Care Programs

A seasonal monitoring program provides you with early detection, diagnosis and a specific treatment program designed by a qualified arborist. Our inspection and recommendations become the basis of your yearly tree and shrub care maintenance plan.

Insect and Disease Control

Insect pests and diseases weaken trees by consuming or damaging foliage, stem and root tissue. We design programs to suppress insects and diseases utilizing the latest practices of Plant Health Care (PHC). Seasonal insect monitoring ensures tree and shrub health with the safest and most efficient control method instituted at the correct time.


Fertilizing improves plant vigor while encouraging growth. Trees receiving regular applications of essential nutrients look better and live longer. Lacking vital nutrients, trees and shrubs are more susceptible to damage from insects, diseases, drought and other environmental problems. Slow release liquid fertilization provides time-released nutrients which help to sustain healthy growth over longer periods of time. Fertilization is an essential part of a successful plant care program.


Proper pruning not only enhances the beauty of your trees, but it is necessary for their continuing health and vigor. Removing dead wood, correcting weak branching habits, reducing wind resistance and improving overall appearance and safety of your trees is of the utmost importance in any landscape maintenance plan. Correct pruning techniques also improve the insect and disease resistance of a tree. Done regularly, proper pruning will help your trees last for generations.

Tree and Stump Removal

Although tree removal is a last resort, there are circumstances when it is necessary. Removal is essential when a tree is dead, considered irreparably hazardous, causing an obstruction that cannot be corrected through pruning, crowding or causing harm to surrounding trees, or is being replaced for a more desirable specimen. Our certified arborists will help you ascertain the condition of your tree and recommend the proper action to ensure safety and tree health. Our modern equipment and highly trained specialists can remove a tree to several inches below ground level, ridding your landscape of unsightly stumps.


Our certified arborists are available to aid in consulting on large projects, pre-construction, insurance related problems, or residential landscape concerns. Our staff can also assist you or your grounds personnel with the planning, development and maintenance of your property.
