Our services

Perfect treescapes start here.


From planning to maintenance and removal, Colonial can handle all your tree-related needs throughout the year.  Our services can be bundled or individually selected based upon your particular needs and budget.  We also offer premium upgrades to several of our services.  If you are interested in hearing about them, let's chat.

Planning and tree planting


The right plan:  When you contact Colonial for your tree-planting project, we consult with you to understand your goals so we can help you select just the right plants for the right place in your landscape.  That's the best way to minimize future maintenance requirements.

Most trees can be planted any time of year, as long as the ground is not frozen.  However, most do best being planted in early fall (think September); autumn's cooler temps and reliable rainfall are ideal for plant establishment and limit potential transplant shock.  Your arborist will advise you on the best time of year to plant the trees you select, and if you prefer to plant during the spring or summer months, he or she will arm you with advice to ensure a successful outcome.


The right plants:  You can have a great plan, but if your plant quality is poor, the final result will be anything but gratifying.  Poor-quality plants can lead to all kinds of problems down the road, from stem-girdling roots and poor structure needing corrective pruning to plant stress that makes young trees vulnerable to pests and pathogens.


We source our plants exclusively from Johnson's Nursery, known for stock of the highest quality.  With your arborist, you can hand-select the specimens you want for your planting project, or we can select them for you - your preference.


Great results, guaranteed:  Proper plant selection, sourcing, and installation allow us to offer you a one-year guarantee on the trees we install for you.   


For the best possible start:  We offer a premium planting upgrade that includes of 2-4 inches of organic, shredded hardwood mulch installed as a mulch ring, staking when needed (and removed after the first growing season), installation of a Treegator® Slow Release Watering Bag to help  provide adequate watering during the establishment period, and a complimentary young-tree pruning visit by a Certified Arborist 2-3 years after installation.  The premium upgrade provides you with a two-year warranty on your tree installation.  Be sure to mention the upgrade to your arborist if that interests you. 

Year-round maintenance


From roots to shoots, our experienced arborists and technicians are on call to assess and identify your tree maintenance needs.  Maintenance services can be requested on an as-needed basis, or you can obtain an annual Colonial Cares Maintenance Package.  Based on a professional consultation, your Colonial Cares package will cover everything you need to keep your trees healthy and beautiful, year-round.
