Tree Health Care From Certified Arborists

Tree Health Care from Certified Arborists You Can Trust.

It is important to understand that happy, healthy trees are better able to defend against insects, disease, and site-specific problems. We perform a variety of preventative maintenance techniques to keep Orange County and Southern California trees in good health. Our tree healthcare professionals will evaluate and monitor your trees. Services such as fertilization, branch bracing, root aeration, spraying and/or injections may be recommended to keep your trees in tiptop shape or to nurse them back to health.

Experienced, ISA-certified arborists from Gruett Tree Company provide complete evaluations and reporting in Orange County and throughout much of Southern California. Consultations cover tree inventories, decay detection and measurement, tree value appraisals, hazard assessments, budgetary management plans, and more.

Our experienced team of arborists serves a wide variety of clients, including many of the real estate developers, contractors, golf course operators, leading commercial and property management companies, estates, and consulting arborists seeking partnerships on arboricultural projects.

Gruett Tree Company is committed to raising the industry standard for arborist evaluation and reporting in Orange County and throughout Southern California!

Tree Wellness Plans

When Gruett is called to a site we take in more than what is going on with the tree. We look at the environment, the other trees, and the plants in the area. This way we can get a better understanding of what your tree is going through. We then take this information and use it to develop a tree wellness plan.

All personalized Tree Wellness Plans are designed to plan out a trimming/maintenance schedule, administration of yearly medical services, along with information on proper care and what to look for before you need to call Gruett. These personalized plans are an easy and efficient way to keep up with your trees needs all year long.

So the next time your tree is acting out of character, let us know since we speak tree.

Did you know that there are only a handful of tree companies that are actually qualified contractors? That’s what makes Gruett Tree Company a safe choice when looking for a bid in Orange County and throughout Southern California. Gruett Tree Company is fully licensed, bonded and insured. Click here to view our license.

To protect you and your property, a professional contractor should be licensed, bonded and insured. The state board of contractors requires a professional to have a valid contractor’s license. Ask for proof of insurance commonly referred to as a general liability and workers compensation coverage. A license should be a class C61-D49. This is not to be confused with a landscaping license, which is a class C27. Should an incident occur, your homeowners insurance could question the validity of your claim. For landscapers and gardeners, the insurance will not cover such loss.

A business license does not qualify as a state contractor’s license. Although a professional tree care company should have both, they are separate licenses. Gruett Tree Company’s contractors license is #707165 C61/D49.
