It's probably early to review a tree planting - the trees' long-term survival is key. But describing our experience with Kelly's might be helpful.
We had 3 trees that had died and needed to be replaced. The arborist came and did an estimate, including sending a photo of her recommended tree species for the replacment trees. The colour of the trees in the photo were green, and there had been no discussion of the colour of the trees with the arborist at all. I had just assumed from the picutre that the trees would be roughly the same green colour as those being replaced.
On the day of the planting, the crew arrived with trees with purple leaves. So, on the day of the job, we had to frantically decide if we could live with the colour of the trees or to send them back and reschedule the planitng. After some debate, we decided to go ahead and plant the trees that had been delivered.
For supposed professionals dealing with trees all day, every day, this kind of mistake is unacceptable. If you hire a credentialed "expert" to do a job, nothing as basic as the colour of the trees should be miscommunicated. The final work order also mised another little job that had been discussed and agreed to. After a call with the arborist, the work was done, but it was another error.
So beware - if you hire Kelly's, don't rely on their professionalism, and instead make sure every last detail is discussed and documented. Ask to see the actual work order ahead of time.
The crew that did the planting itself were fine. They were careful to keep the worksite tidy, and even pruned another tree for us as they were wating for us to decide whether to keep the purple trees.
Finally - their fertilization/aeration services appear to be a bit over-priced for the work that actually gets done. Definitely shop around if you want this kind of service.
