San Diego's Greentree Arborist

If you are lucky enough to stumble upon Green Tree and have the opportunity to meet Gary Walker you won't be disappointed! Gary did a fabulous job pruning our Canary Palm to look like an "Egyptian Work of Art!". It is so beautiful it deserves to be gracing the front of a swanky resort rather than our front lawn. He also trimmed back an old mulberry tree and did deep root fertilization of both trees. Gary pointed out that the mulberry tree had some termite-infected limbs which we were unaware of. He was able to cut out the affected areas. We are very pleased with the work. Thanks Gary!

I met Gary through my neighbor who needed a very large pine tree removed and much of the foliage was hanging over the property line into my yard. So Gary and his crew needed access to my yard to remove the cuttings. While they were available I got Gary's advice regarding 3 Canary Island pines growing in my yard near the neighbors's tree. My trees were growing when I moved into my house in 1985 and I had never done much of anything to them. So they needed trimming and fertilizing and alot more water than they had been getting. The trees have been rehabbed and should be doing alot better in the future.
Gary's prices were good. His workers were friendly and helpful with offers to put things anywhere I needed. The clean-up afterward was very thorough and colateral damage to other plants was minimal. I asked for some of Gary's business cards to have handy for referrals. It was a good experience.

This is the second job Gary has done for us. It involved replacing a rather flat and completely dead lawn in our front yard with a flagstone path and a variety of plants, selected to be hardy in the hot, dry conditions and not to use excessive water. The project also involved changes to the main irrigation system and the installation of a new small-bore, drip irrigation line. Gary's strength is his knowledge of plants and trees, so now we have a rich assortment of roses, sage, lavender, mallow and crape myrtle trees. These vary considerably in height, color and texture, resulting in a space that is varied in height and density, giving a perception of considerable complexity - it is a pleasure to walk along the flagstone path.Considerable quantities of mulch were supplied and spread, which not only controls weeds and reduced evaporation, but gives a unity to the new landscaping and a continuity with the existing planters.

Gary had an initial meeting with us, produced a quotation and had a second discussion with us before we agreed terms and authorized him to begin. The total cost was more than we planned, but we agreed to this and, indeed, Gary provided some extra plants at his own expense. So far everything is working well, plants are growing. On the other hand, the flagstones were selected to match a large existing area and so there was a restriction on choice.

In general we are pleased with the work. The landscaping of the front yard looks good and will become even better as the new plants and trees grow. On this basis we would use Gary again if the need arose.

I hired Gary Walker and Greentree World to lace and fertilize my two pittosporum trees. Both trees are over 60 years old and provide a gorgeous canopy of shade in my backyard. Unfortunately, too much shade. Gary and his team of experts did a great job of opening up the canopy and pruning appropriate limbs to give the trees a healthy, airy look. Because of drought conditions, they performed a deep-root fertilizing and provided me with tips on improving the health of the trees going forward. Gary was knowledgeable, personable, held to our schedule and just did a grand job. With his horticultural background, I knew I wasn't just hiring everyday tree-pruning monkeys. I hired an expert. I would recommend Gary and his services to anyone who cares about trees. Great job!

I was worried about the health of my beautiful, tall palm trees. I had called two other companies, but neither had gotten back to me. Gary promised to call me back, and did, and showed up at the appointed time, and, as promised, called ahead to let me know he was on the way -- so very professional.
Gary quickly assuaged my concerns about my palms, but then let me pick his brain about all the other plants on our property. He gave me great information about all my plants as we walked my property, in a short period of time, and lots of tips on the proper care and feeding of them. He is obviously very knowledgeable, but more importantly, eager to share. I highly recommend his services!

I hired Gary Walker and his team at Green Tree to come and lace out two very tall trees and remove a cypress tree on our property. I was very impressed with the way the trees were laced to bring out their true beauty. The team worked quickly and cleaned up all of the mess in 2 1/2 hours. This is a crew that really cares about the trees and making your property look great. I would highly recommend them.
Thank you for being a great guy and doing a wonderful job.

Earlier this month I called Gary / Green Tree to discuss two tree pruning projects for our family - one in La Jolla (large job - long overdue) and Encinitas (small job - corrective work). Gary not only returned my call promptly, he met me within a day or so, after having viewed both sites on his own initiative. Like other reviewers note, he thouroughly explained my options for each particular tree type and made quite sure he understood my objectives for each. Finally, we agreed on a work schedule, which he met. While all this may seem a normal process, I must say in my experience Gary's service, punctuality, attention to detail, and knowledge are outstanding - no last minute calls to delay the project, no surprises, no mess for me to clean up. Gary was even able to include additional work that I requested during the larger job. Both pre- and post-op, Gary advised me of the appropriate care for the larger trees and later followed up to make sure I did my part.

Impressive; I highly recommend Gary.

We feel lucky to have found Gary, who is proof that that great customer service lives on! He and his team trimmed our trees this year along with some other tree care and also removed some trees that were too close to the house. We learned a lot at the consultation and he worked with us to establish a good quote. He is not only extremely knowledgeable, but communicates this effectively to the (non-expert) customer to help you decide on your plan for your yard!

We recently used Gary, from Green Tree, for a landscaping problem at our home. He was prompt, gave us a fair estimate and completed the work as scheduled. Gary was also very helpful in providing us with ideas and solutions for our landscaping. We highly recommend him and would call him in the future when the need arises.
Thank you, Gary!

Gary was doing a job in our neighborhood when we asked if it would be possible to cut two yucca
stumps to ground level. He did it at no charge(we don't own a chain saw) and saved us hours of labor.
He will be our new "go to" guy for gardening and tree needs. He spent time talking to us and seems most
knowledgeable. Thanks Gary!

Gary did a great job on our trees.
Him and his crew completed the job with great skill and quickly.
I would reccommend him and his crew to anyone out there trying to fix up any landscape issues and especially helping keep your trees/plants healthy for the life of the species.

rating 10 out of 10.

I met Gary when I asked him to evaluate my palm tree. I was sad that I had to remove the tree because of its poor condition but was glad that he was able to re-do my yard. My goal was to remove grass from the front yard to reduce water bills, but I didn't want to have desert-looking yard. I asked Gary to get water-wise/heat-resistant plants with flowers. He asked me my favorite colors and type of flowers and tried to accommodate my requests as much as possible. In addition to trees/plants with flowers, he also planted bulbs of daffodils throughout the yard (but didn't tell me where he put them), so it'll be surprise when start growing soon. I can't wait to see how it turns out when all the flowers start blooming. He also artistically pruned a large ficus tree in the side yard, repaired my side gates, connected one of the gate to walkway with large flag stones, and put trees and ground covers in the backyard. All of these are a package deal. Thank you or Domo Arigato, Gary!

Gary Walker and his team removed a couple of bottle brush trees and trimmed and laced several other mature trees for us, including two large pines in the front yard that had been butchered by someone else. Gary managed to fix them up and get them looking happy again. He also did deep root fertilization. We were very pleased with the results. Gary did a fantastic job and the price was very reasonable. We definitely recommend him.

Gary recently completed a very nice job of lacing three mature pine trees in our yard. He artistically reshaped the trees allowing the sun to shine through, which is exactly what we wanted. The outcome is beautiful.

My wife and I have turned to Gary twice now. We have three acres in Bonsall, and have lots of trees. Gary has taken care of several large eucalyptus trees, a bunch (upwards of 20) of California pepper trees, several stands of old, tall oleander, a huge pine tree, and several palm trees (including removing one we hated). Gary and his crew did great work, thinning the trees out in a way that looks natural - definitely NOT like someone just gave it a quick once-over with a hedge trimmer or something. Gary also advised on care for a couple of trees we were concerned about, and gave us some good instructions for making our trees as healthy as possible. He even cut back our roses so they're all set to grow like crazy in the spring.

We had him do a lot of work, so it wasn't cheap, but we think it was a good investment. Gary is our go-to guy for tree care, and we like the work he's done for us.

He's also a musician, and has put out a CD album. Pretty good stuff, actually!

I would highly recommend Gary & his team!!. I have a 60 ft. pine tree in the corner of my backyard. It was planted there from a living Christmas tree we bought 30 yrs. ago. Every three to four years I have had the tree laced & trimmed , but it had starded to grow over into my neighbors yard and although they never complained it was overwhelming that corner of their yard. I had asked other arborists if there was a possibility of cutting the major branch that had grown into my neighbors yard, but they all said that cutting that much off my tree would kill it. I was beginng to think that I would have to cut it down although it held a great sentimental value to us , having watched it grow all these years. Then I saw Garys' website & started to read about him. Within a few minutes of reading about his knowledge & passion for nature I knew that if anyone could save my tree it was him. What was great about Gary was the confidence that he gave me about what he needed to do. There was no hesitation in him telling me that major branch would have to go & that my tree woud still look & be just fine. Afterwards he did some light lacing & reshaping and also did deep root fertilization on not only my pine tree , but other trees I have. My pine tree looks Great!! Garys' team is also the best I've ever seen! They were quick & their cleanup was amazing. They even did firewood cuts from my tree , which I gave to my good neighbors for putting up with my tree for so long. His pricing was right there with everyone elses, despite the fact that he comes with more knowledge & passion for what he does. Gary & his team are the only ones I will ever have work on my trees again. By the way, Great music Gary , Thanks

Gary Walker had recommended thinning, pruning, lacing and fertilizing our trees on our property here in Valley Center, CA. I was a little skeptical of his original estimate to do this job at first but I can see now that it was worth paying a little extra to get our trees treated by him and his crew of workers! The job was done exactly as he recommended and in a timely, professional and reasonable fashion. The area where they worked was left clean and I was very happy with the results of their labor! My huge, well established pine trees needed and got the TLC that Gary suggested and I am very happy to see that he is quite knowledgeable about the care of trees. I highly recommend Gary for any type of work that you might have with your trees!

We recently purchased a distressed, drought stressed, neglected mess of a second home in Rainbow. The 1.65 acre property has two giant ancient California Live Oaks and an ancient Giant Sycamore. In addition, there are perhaps 30 additional trees, plus innumerable shrubs, bushes, succulents, vines etc. Much of it was dead or close to death. We needed the services of a knowledgeable arborist who could devise a plan to save the trees and guide us through the first steps of restoring the property. Although Gary's bid was not the lowest, we found his expertise worth the investment. Moreover, Gary answered his phone personally EVERY TIME I CALLED! We are working professionals with extensive family obligations, and we are only on the property one or two days on the weekend. When I needed answers, I got them immediately.

Gary devised an intervention plan of deep root watering, fertilization, and trimming/pruning that has our property back on the road to helath. Gary and his crew did everything he said they would do in a timely manner. He turned our jungle into a yard by clearing 80% of the brush and dead branches and making the rest of the restoration manageable. When I saw the sculpting Gary did on the Giant Sycamore, it brought tears to my eyes. It is stunning!

For Gary, trees are Living Art. I would not hesitate to recommend Gary and GreenTree World.

We were interested in replacing the grass in our small front yard for a low water garden. Gary got a good idea of the kind of plants I like, and then custom designed a garden specifically for me. Gary and his crew were very efficient and done in a matter of a few days. In addition to the front, he also laced out two trees in the back. Our Olive tree and Brazilian Pepper tree have never looked better! And the plants he chose for the front are absolutely beautiful. I can't wait for my Hong Kong Orchid tree to start flowering. Thank you Gary for the beautiful yard!

Gary and his team took a half acre of overgrown, dense eucalyptus and safely removed many trees and large branches that posed safety risks (even one that was precariously hanging over our neighbor's roof). He transformed a wild yard (Gary dubbed it "the jungle") into a few natural looking groves that allow lots of light and leave the yard feeling more spacious.

He saw the potential in our space and applied an artistic eye; we love the finished work and are grateful we found him, as other arborists did not seem to understand the complicated nature of the job, and the result we hoped to achieve.

Gary and his crew were great. They were able to come within 30 minutes of my calling them about a 40 foot pine tree that had fallen down overnight obstructing the road. They took care of the pine tree, laced my ficus, and provided free fertilizer for several other trees. The job was done quickly and they cleaned up everything, even blowing and sweeping my neighbors' driveways. Wonderful service. I will recommend them to all my friends and neighblors.

The breezes are blowing through my newly laced trees. What a difference a day makes. We were thrilled with the work that was done by Gary and his crew. The crew was amazing and then the final touches as seen through Gary's eyes were wonderful. Details, details.....all of them covered so professionally. A friend had recommended Gary. She said she loved to watch him work. Now we know what she meant. .

My husband and I invited Gary to redo our front and back yards (completely decimated due to a home remodel) after reading positive reviews about him, including those from a column in which master gardeners were asked who they would choose to do their landscaping - more than one recommended Gary! He designed and planted our gardens last September (2011). During the design phase, we met with him at our house (this was when it became clear to us that he was just the right person for the project) and then he generously invited us to visit his gardens, and asked us lots of questions about what we liked. I remember telling him that I wanted a natural, green, lush, bird & butterfly-friendly, tree-laden, drought-tolerant, and low-care garden, all for a very reasonable price (only semi-joking). Then we basically set him loose, as his knowledge and creativity were evident. Gary and his team implemented his design in about two weeks. I'm writing this 8 months later, and it's incredible what a transformation we have witnessed. The yard is lush and full of greenery, we have hummingbirds and butterflies everywhere, and it seems that every week a new and unexpected splash of color emerges - just today we noticed small purple flowers on a bush, and burgundy trumpet flowers from one of the new trees. Gary put in a wonderful variety of shrubs, trees, and flowers that integrate to form a truly artistic tapestry. I've emailed Gary on several occasions with questions about various plants, and he's been gracious about answering my questions. He's even helped me find replacements for the small number of bushes that I managed to kill. Gary combines extensive knowledge of plants with artistic talent and vision, and he was a great match for us, as we were happy to step back and give him free rein to create!

GreenTree and Gary did a great job removing two palm trees from our back yard, as well as trimming and lacing 7 other trees aroung the house. We have a magnolia tree in front which I was thinking about having removed, but Gary convinced me to have it "artistically" pruned, and it looks fantastic. I will definitely have GreenTree back for any future work. Gary also gave me some advice on perking up a fishtail palm.

My quest for an arborist started when I noticed a volunteer Coast Live Oak tree growing among some Junipers on my property. I wanted to keep the Oak tree but I wasn't sure if it was growing in the right spot. I started calling around for certified arborists for advice and estimates on what to do with this Oak tree. I also needed advice on 2 mature Ash trees as they were in definite need of some TLC.... After 3 estimates from "Certified Arborists" I came across GreenTreeWorld.com on the web and I liked what I read about Gary and his great passion for nature. Needless to say, I choose Gary over the other 3 arborists not only because of his passion for nature, but because of his analytic ability to look at a tree and disect it in a way to restore the tree statuesque beauty! Thank you Gary .... IMHO you are the "tree whisperer" !

Gary and his man came promptly as promised and they did a terrific job!
They cut two trees and trimmed and laced my other trees. They look GREAT!
Thank you for your help!

Gary just finished redoing my yard and truly turned it into a garden. My best friend couldn't wait to come over and look at the completed project and when she walked in the gate she just stood there and said, "Wait. I have to take it all in. OMG! It's absolutely beautiful!" She went on to say, "You can see his artistry in the placing of the plants and the colors." We just sat and looked at this amazing change that took place in just a couple of weeks.
I'm so glad my husband found Gary's website and we decided to have him do the work. I can't wait for next Spring when it's all established and in full bloom! Thanks Gary!! :)

When I got home and saw all the work that had been done and how beautifully it was done
I was more than pleased. The cluster of elms were no longer entangled and droopy. They looked young
and regal. The ficus was gone, poor thing that I never should have planted. It was quite large and the
only trace of it was the stump. Great job cleaning up!
The neighbor's tree that was shading a lot of my driveway and blocking the sunlight on my solar panels
was cleanly trimmed. And last but not least, my liquid amber in the front yard, looked healthier after Gary laced it.

Gary's an artist with trees.

Gary and his crew have been to my home twice to work on my trees. In both cases the work was superb. Gary clearly lays out his plan to accomplish the needed work. Then he and his crew complete the work in a professional and timely manner. Everyone seems to enjoy the job they are doing. Before they leave, everything is neatly cleaned up.

I find Gary’s suggestions very helpful. I met him when he was working on my neighbor’s property. I would highly recommend him to all for his tree and garden work.

Gary just finished our property and did one fantastic job, front, side back. Trees were sculptured in an excellent manner and his recommendations on care and feeding the trees were positive. I had been satisfied with my previous contractor but Gary is significantly better and very efficient. He and his crew were here a shorter period of time, did a better job on the trees and cleaned up all the work. I will use him again.

What a pleasure working with Gary! He provided great expertise as an arborist for the trees in our yard in La Jolla, laced out our overgrown trees into pieces of art. His suggestions for new plants and shrubs gave the garden a beautiful theme. The work was done a few months ago and we are now seeing the results with beautiful surprises popping up all around. He and his crew were very professional and very easy to work with. He followed up a couple of months after the work was completed to check on the results. We could not be any happier with Gary’s work and will definitely use his services and recommend him in the future.

Gary has inspired me to be a better gardner. Our yard had ended up in sad shape, and I was embarrassed to even have Gary see it. He never said a disparaging word, yet instead encouraged me and gave me helpful tips. He and the guys artfully laced out all our big trees and largest shrubs. They were on time, careful with the surrounding plants and cleaned up nicely when finished. Even my neighbor came over and hired him !
I can hardly wait till Spring to see my yard come alive!
Thank you Gary !

The property of our new house is well-stocked with old growth trees, which had not been cared for in years. We suspected some of them were not fairing well, so we decided to contact an arbor specialist -- and we are glad we did! Gary not only confirmed that our trees needed a lot of attention, but he was so articulate in his analysis that even us non-specialists could comprehend the problems and the necessary, common sense, solutions.

In two visits, Gary provided deep root fertilization to all our trees and did a magnificent pruning job. His prices were very fair and he and his crew were on time, professional and thorough. As they we were working, they found some other small jobs that needed attention around the property and simply did them at no extra cost.

Throughout the process, it was clear this is a calling for Gary and he loves his work. If you want someone who is clearly an expert in his field and passionate about making trees healthy, vibrant and beautiful, Gary's your man!

Well, that was quite an adventure! A cat was stuck in one of my trees for two days over the New Year's Holiday, and the poor owner (a darling 15-year-old girl) and her mom could only look on helplessly, trying to coax it down. It must have been 50 feet up. The Fire Department stated that they don't take cats out of trees anymore. Animal Control's ladder truck was broken, and they hoped to come out in a few days (never did). I and some neighbors tried to get the cat down ourselves with all kinds of approaches involving tall ladders, high climbing, poles, ropes and nets. By 9:00 p.m. on New Year's Day, we had to give up because all we had succeeded in doing was spend a bit of money at the Home Depot, and drive the cat even higher where we could not see it, and it had stopped meowing its location. In the morning, we were able to see it about 60 feet up in the canopy, meowing piteously. At 7:10 a.m., I decided to call Gary.

By 8:30 a.m., he and his crew were there. In no time, a hero was up the tree, had the cat's limb roped off, and was sawing it free. The cat was ultimately released to a cushioned semi-controlled fall, and it sprinted home, where it began to drink like crazy.

Although such was not really the purpose of Gary's visit, he likes for people to get value for his money, so, while the crew was there, they cleaned up the other trees, and hauled away the dead branches and trunks.

Gary had a full day's work calendared, but he put us at the top of the list to do something beyond his normal scope of work. He was friendly and caring ever step of the way. His crew were consumate professionals. I have nothing but praise for this professional service.

Thanks!

Gary and his team performed an outstanding service and I am more than pleased with the results. They pay attention to detail and were kind enough to haul away all debris as well. Thanks again Gary and will recommend you in the future!

Call Gary! You'll get a quick response, speedy timeline, GREAT PRICE and a GREAT WORK! I had a whole pile of work to be done and his team completed it all in one day, the very next day after we first spoke. The trees look MUCH better and healthier now and he even helped me out with complementary fertilization and mulch since we are a military family. Seriously, I can't say enough great things. I highly recommend Gary and his tree team.

Gary is fabulous. He removed 4 clusters of mature tree roots and planted King Palms in their place. Unbelievably quick response, incredibly reasonable price, awesome result! I couldn't be more happy with choosing Gary's company. Extra bonus: he actually clipped roots with small hand tool to avoid damaging my irrigation system. I heartily recommend Gary, he'll be my tree guy for life.

I hired Gary to consult on a new tree and landscape plan at my property nicknamed The OC. Upon his arrival he immediately commented on my existing trees and what I should do to reduce their current state of stress.
We started with a blank canvas, and dove right into the plan, new ideas flowed and current ideas fine tuned. You could feel the passion and knowledge in his words. Ideas came so quickly my brush couldn't keep pace. He welcomed my ideas and listened carefully, interjecting sound suggestions that only a person with his vast experience could offer. A very creative, knowledgeable, passionate expert!
By the time the session was done, the canvas was complete and a masterpiece born!
Hiring him will save you time, stress and best of all money.
Plus, you will have a yard that will stir envy in all your neighbors.
Thanks again Gary!
Mike

I feared my trees (chinese pistashe) were dying - leaves yellowed and dropping. Gary came out - and did a health appraisal and a deep root fertilization - 2 weeks later, the trees are healthy and growing new strong leaves again. Gary also provided an assessment for the other trees in our yard (dispelling comments by other "experts" who's solutions were to cut them down and buy new). We will definitely call Gary again when we need expert help (vs the local box store folks). Thank you again Gary!

Gary did an excellent job at our home in La Jolla. He was on time for a free estimate. He gave thoughtful advice on a plan for our yard. His estimate was significantly less than other bids. Greentree fit us into their schedule quickly. They came on time and finished the job in one day. We will call Greentree the next time we need help with our trees.

Thanks for fitting us into your schedule so that we had our view for our party. It looks great and we appreciate your expertise.

We're totally satisfied with Gary's service and feel we got very good value for the price. He laced a poplar tree that had been ignored for fourteen years and it looks great. We're trying to revive a large old tree in the back yard that looks sickly. Gary explained what was going on with it and what we need to do to hopefully save it. He came out on short notice, arrived on time, and did a great job on clean-up. Highly recommended.

We are very happy with the service that Gary provided. He laced out a large tree in our back yard and took it from a huge old overgrown tree to a work of art. We will now enjoy our deck so much more. He also went above and beyond, and trimmed up another smaller tree and a large overgrown honeysuckle as a bonus.

Thank you Gary.

Michael

I would highly recommend this tree service company.
Gary was able to remove 2 trees for us the same day we called. All green waste was hauled away and clean-up was great.
His years of experience and knowledge to keep trees looking healthy and visually appealing will make your yard look great.
A healthy green-space will keep you in an upbeat and healthy state of mind.
Call Gary to keep your trees happy!

I would highly recommend Gary and his team. He was very knowledgable and took care of my dead trees promptly, stacking the firewood as well. His attention to detail is wonderful.
He was prompt in returning my call and came out the same day and gave me an estimate.

Gary did a great job thinning out our massive pine trees and carrotwood. I appreciate his attention to detail and the care he took in working on our trees. I would recommend Gary to anyone needing the services of a certified arborist.

One of the major surprises about Gary is he picked up the phone immediately the first time I called, and came out to give me an estimate the same day. That is big for me, I'm from No Call and prompt is always of primary importance. I choose Gary because he is a botanist, and an artist, I knew he could see where I was going with an artists eye. Green Tree did a beautiful job, the trees look great and my yard is looking better.

This is the guy to use! Gary laced our Carob tree and did an incredibly skillful and artistic job. It's a tree that had been neglected for over 7 years, and badly pruned prior to that. Gary was able to completely revitalize it, and even though the change was dramatic, it looks spectacular (instead of butchered and violated like trees so often do after aggressive pruning). He was noticably attentive to the unique character of this particular Carob, and it's obvious that the tree is going to do so much better now. What a great reboot!

Gary was extremely helpful with our tree needs. We were very pleased that Gary convinced us to keep our mature pepper trees and not just cut and grind them down. We had 3 trees removed and 3 trees laced and he did a wonderful job with great clean up too. I will certainly refer Gary to anyone who's in need of a skilled arborist.
