We offer a suite of tree, shrub, lawn and deer deterrent services to help maintain the health and vigor of residential and commercial properties. Our team of arborists specializes in tree, shrub and lawn conditions specific the Northern Westchester river towns, Putnam County & Dutchess County. Our services do not include lawn mowing or tree planting.

"I scheduled a fertilization and tree pruning in August 2021 to take place in September. SavaTree did the fertilization on time, but did not come back to do the pruning. Made multiple calls where I was told they would look into it and then I would not hear back. When I called for the third time in late October, I was told the pruning was scheduled for January 2022, but they may be able prune in late November. I cancelled at this point and asked for my deposit back. It is not good customer service to promise a date, not call back if the promised date can not be met, and also not get back to me when I call multiple times."

"I had my front steps of my house done. The job was poorly done. When I asked if my steps were going to look like that when it was completed, I was told yes. He told me all my steps were different sizes. What he failed to say was he cut them wrong. So he lied to cover up the mistake.Because of the slabs being cut incorrectly he put pieces on the end of the slabs to fill in the gaps. It looks like a bad puzzle. Terrible job. Not professional at all. I’m so disappointed that I wasted my money on this company. I do not recommend them at all."

Servicing Northern New Jersey & Southern New York We accept our responsibility to the environment, society, and future generations to be leaders in environmental stewardship.

"I have been a customer of Go Organic for approximately 22 years. I had switched to Go Organic after the prior lawn treatment service was using chemicals that negatively impacted my dog (actually gave him seizures). Once I switched, all problems with my pets went away. In addition, my lawn has never looked better! Over the years I have always been impressed with how thorough and knowledgeable they are. I had the good fortune of bumping into one of the technicians, Maynor, last week. While he treated my lawn, I stopped him to show him a couple of problem areas (very minor!). He was courteous, knowledgeable, and happy to help. Overall this is a service I would have no hesitation recommending to anyone. "

Family owned and operated since 1964, Almstead Tree and Shrub Care Company is proud to offer expert service to both residential and commercial clients. Whether you're in the market to save a cherished tree or manage an entire campus, you can trust Almstead to handle your goals and concerns with the utmost professionalism. Contact us today. www.almstead.com

"High marks for following through and meeting their commitment and doing great work. I had an Almstead arborist review the property and provide recommendations on some dead limbs and trees. We came to an agreement. When the crew came, the arborist wasn't there (later found out she'd left and moved north). As far as I could tell, the crew didn't have the instructions we'd agreed on and they did some, not all of the work. What followed was back and forth, but after a few months they sent out the crew to remedy the missing work. They did a great job and I was very glad. I appreciate the office staying on it and making it right. I've used them for 24 years and happily look forward to continuing to use them. It's a lot to trust your trees to someone!"

Lawn Fertilization and Treatment questions, answered by experts

You should water your lawn two or three days before putting down fertilizer to ensure it can properly absorb it. It's good to apply fertilizer if the ground is moist, but you want to avoid overwatering or flooding the area because it can prevent the grass from absorbing the nutrients. Consider weather conditions when scheduling your fertilizer treatment and read the instructions to see how long you should wait to water after application.

If your lawn has a higher pH than recommended for your type of grass or it looks yellow, sulfur can help. If your lawn is slow to grow and not very lush, it could also benefit from a  higher sulfur content. Sandy soil is especially vulnerable to sulfur deficiencies.

Yes, especially for properties focusing on curb appeal. A well-maintained landscape supports visual and environmental attractiveness, potentially increasing desirability.

A lawn that suddenly and quickly turns yellow is typically the result of a dramatic change in the grass's environment. Heavy rainfall can dilute soil nutrients, rapidly yellowing the grass, and dull lawn mower blades can dry out and damage the grass in a short time. Over-fertilizing can yellow a lawn within a matter of days. 

Services typically include mowing, edging, trimming, and debris cleanup. Additional options may consist of fertilization and weed control.
