Horticulture Unlimited did landscape renovations and installed a new drip irrigation system at my first home. I decided to have them come to my house twice a month to maintain the landscaping at my second home. Their landscape maintenance crews are meticulous. Over the past year, they have done a wonderful job in maintaining my landscape at a very reasonable price. I am very pleased with the landscaping service I have received thus far, and I recommend Horticulture Unlimited without reservation.

  • Useful Website, Fast Response, Excellent Workmanship, Fair Price

These guys are excellent landscapes! Being new in Tucson, I had no idea about desert plants, so I decided to do some research online. The Horticulture Unlimited website gave me a ton of information and allowed me to request a quote for plant installation online. They contacted me right away and came out to my home the following day. The gentleman who came out took a survey of my yard. He showed me pictures of various native and desert-friendly plants that he suggested I install, and he provided an estimate for the cost of the plants and the installation. The estimate was reasonable, so I gave him the go-ahead to do the work. Horticulture Unlimited completed the work fast, and I was very impressed. Everything looks great. They are truly landscape professionals!

  • Quality Work, Reliability, Knowledge

As a Tucson business owner, I recommend Horticulture Unlimited for landscape maintenance. They are reliable, professional, and they know the plants. There are several "landscaping companies" in Tucson, AZ. Many don't know enough about desert plants or how to keep a lawn green in the summer. Most are not reliable. When my last landscaper failed to show up, I found Horticulture Unlimited. They've maintained the grounds around my business for about three years now. They keep the lawn green, the grounds clean and the trees and plants healthy. I'm glad I found Horticulture Unlimited, and I would recommend this company to friends and fellow business owners.

  • Knowledge of Arid Plants, Turf and Irrigation Requirements
  • Higher Cost

It is my pleasure to write this review of the quality workmanship provided by Horticulture Unlimited, Inc. I was previously dismayed by a recent experience with another Tucson landscaping company who installed several plants and turf that didn't survive the summer. Horticulture Unlimited renewed my faith in landscape contractors in Tucson, AZ when they replaced the dead bushes and revitalized my dying lawn. They also upgraded my irrigation system and gave me some detailed instructions on how to care for my landscape. Their services were more expensive than the other landscaper, but well-worth the extra cost. My yard is now attractive and sustainable, thanks to Horticulture Unlimited.

Customer Testimonials

Stouffer Construction has been working with Horticulture Unlimited for over 20 years. We have always had a good relationship with Dawn & Dave and they have always provided excellent work on both residential and commercial jobs for us. Their staff is knowledgeable and easy to work with and they always use the best subcontractors for hardscape work etc. I highly recommend Horticulture Unlimited for ALL your landscape needs.

A Horticulture Unlimited tree crew, Ron and Eddie, trimmed a large mesquite tree in my yard this afternoon. They were professional in every aspect, communicating with me about what they were going to do and why, and showing me the result of the trimming with an explanation about how the tree was going to adapt and fill out. They went above and beyond by leaving my yard cleaner than it was before they arrived. Their care about the quality of their work showed through. While at my house, we discussed future care for the tree as well as landscaping ideas for a project I plan for the future. I really appreciate having this done and will definitely use this company in the future.

Eddie and Ron just finished cutting down a huge palo verde in my backyard. Beautiful job. You can't even tell there was a tree on that spot. Great, friendly hard-working crew. Thanks!

Horticulture Unlimited is the most professional tree service we have ever used! Ron, Eddie and Anthony were extremely helpful, performed excellent work and clean-up after trimming was immaculate! Thanks guys!!!
