To say that these guys are professional is an understatement! They are true masters of their trade!!! When Rene stopped by the first time - he didn't say much, just gave me the price and left. I knew right there that I was dealing with a person, who knew exactly what he was doing. Surely enough, on May 3 - they arrived as scheduled at 7 AM sharp, tried to be quiet, not to wake the neighborhood needlessly, while setting everything up.
They masterfully removed a large pine tree on my backhill. And the final "blow" was literally when they used the blower to clean up my street, way outside of their immediate place of operation. WOW! I'm not bribed or otherwise coerced into writing this review and I sincerely wish AC Horticultural Management, Inc. with it's WONDERFUL employees and Mr. Rene Castillo to continue the legacy of Rene's father, who started the company and to deliver this incredible value and goodness to the community for many more generations of the honorable Castillo Family!!!

Rene and his crew are masters at both tree removal (when necessary) , pruning and landscaping yards to bring out the full potential of plants and trees. My front and back yards needed substantial work. Rene had been recommended from a friend who needed an incredibly old and large tree removed (and roots) because of the damage to a building structure. It was amazing to see how this mammoth job was done!
Totally professional! When I needed work done on my own home, I knew he was someone you could trust. He's fast to meet with you, oversees what needs to be done (while wanting to maintain trees as much as possible) and his price is really reasonable. To some it may seem unbelievable, but my plants and trees seem a lot happier and healthier now that they are pruned and ready to grow back. It was a joy to work with Rene. I highly recommended his company, as others recommended to me.

I have used AC Horticulture three times over the past 10 years and this last service was even better than the first two! The crew was very conscientious about getting my garden furniture and decor out of the way of falling branches and debris and then restoring it once they were done. Each crew member was unfailingly polite and respectful. They did a great job on 5 trees, a bunch of overgrown shrubberies, removing an unwanted volunteer or two and de-fronding a 12 year old palm tree that had never been trimmed and was a brushfire torch waiting to happen. They cleaned up thoroughly - even skimmed my pool of stray leaves and twigs! Everything looks so good now!! Rene and his guys are the best!

Amazing team of hard working guys! Rene was fantastic and very knowledgeable. They removed two trees, trimmed some huge trees, trimmed a tangerine tree and a few smaller trees. They also planted two new trees. I couldn't be happier with their work. They were respectful of my other plants and trees, cleaned up so well it was hard to tell they had been there! I love the trees Rene suggested I plant. I would 100% recommend them if you need trees trimmed, removed, or planted. Thanks guys for a job well done!

We scheduled a free estimate online with Renee and he never showed up we emailed him and he never responded. When I called the company they said he was out and wanted to charge me for the free estimate for him to come and see our tree and advise us on what to do. The response is not the truth how could we request a service if we had no idea of what needed to be done. Be very careful I would strongly avoid read other reviews. We did find a couple of other very professional and honest companies who came and were willing to give us their opinion as to what needed to be done and costs for those services.

150% impressed with the work done! This is the second year that I contacted Renee for Palm trimming in my backyard. His team arrived exactly at our scheduled time and diligently and professionally completed the entire project in under one hour. I have 4 queen mature queen palms and 5 pigmy palms. Each were expertly trimmed with old heavy fruit stalks removed! All was cut down, hauled to my front yard, everything chipped at the street, and my yard completely cleaned up. The entire crew was communicative, kind and worked as a fluid motion. I highly recommend contacting Renee at AC Horticulture for any of your tree trimming needs!
