Healthy Soil = Healthy Tree

Trees often need help to stay healthy, especially in urban settings. Deep root fertilization is a wise investment in your trees to help them look good and live a longer and healthier life.

Customized Deep Root Fertilization

Tree roots need a healthy soil, the proper balance of nutrients, and air (or oxygen) in the soil to stay healthy. Our deep root fertilization is a process where a high quality, custom blended, nutrient solution is injected into the root zone of trees. These materials are injected under pressure which helps aerate the soil and provide much needed oxygen for the root system. The solution encourages microbial activity to enrich the soil and increases the nutrient levels, providing for a healthier and longer lived tree.

Our fertilization mix is a custom mixture specified by our group of plant pathologists and manufactured exclusively for our company. Our consulting arborist may recommend amendments to the standard mixture when certain nutrient deficiencies or health concerns are present.

The soil injection begins just below the surface and goes to a depth of twelve to fourteen inches. Soil injection sites are placed two to three feet apart in a grid pattern under the canopy area and beyond, in some cases.

When Should I Fertilize My Trees, and How Often?

When your trees will be fertilized depends on the recommended frequency of fertilization applications, as well as any additives included in your fertilization blend.

For most trees, fertilization programs should be repeated once or twice a year. There will be instances where severe root damage has occurred, soil compaction exists, or other health problems are present. In these cases, our consulting arborist may recommend increasing the frequency of applications and/or an additive to help offset problems.

Thank you Aspen Tree Service. My trees look beautiful!Your people were very professional and knowledgeable of what to do and how to do it. I would recommend Aspen whole heartedly to everyone.
Thank you to arborist Tom Waswick who checked my trees and delivered a reasonable bid for the work I requested.Special thanks to Diana for working with me to schedule my tree service around the schedule for sewer line replacement work that kept changing because of rain. She was so kind to me!Thank you to the crew of six men who completed the work efficiently and to my absolute satisfaction. The crew also cleaned up so well that you would hardly know they had been there.I will use Aspen Tree Service for any future work needed on my trees.
Wonderful job!
Excellent job. Professional.
Professional and knowledgeable.
Aspen Tree Service did a fantastic job trimming our three very tall and mature trees for the home we just moved into. They showed up as a team and made quality work of it and cleaned up well behind themselves. Thank you!
Aspen provided a very professional service at a very reasonable price.
It is rare to find an excellent Landscape & Tree Trimming company; who will answer their phones, schedule an appointment, make their appointment, be on time for their appointment, schedule the work 3 weeks out (not 6+ weeks) (Aspen Tree Trimming actually moved up their appointment 1 week), show up for the work on the day scheduled on time, and do a FABULOUS job!AJ’s team went above and beyond to provide a spectacular landscaped yard, displaying raised canopies throughout our gorgeous trees. They removed the brush and the stumps from a previous tree trimmer who never came back to finish the job, along with discarding tree branches & debris. I have already referred Aspen Tree Trimming to one of our Top Producing Agents at Coldwell Banker Apex and will refer to many more confidently! Thank you so much AJ and your Team! 😃 We appreciate YOU ALL!
Aspen Tree Service injected nutrients into an old elm tree in our front yard that we want to save. They were knowledgeable and professional in providing this service. This is the second time we have used Aspen. They have become our "go to" tree service.
Loved working with Aspen Tree Services.Aj and Aaron really know what they are doing and are easy to communicate with. I definitely ended up with the aesthetic I wanted! Would recommend and will use again!
Did an excellent job, very thorough and clean. Great to work with
Responded promptly and was professional. Very reasonable pricing for the work performed. Thank you Aaron!
As an independent contractor, I sometimes encounter projects that are beyond my abilities as an individual. I have partnered with Aspen tree service on many occasions over the past year or so to provide exceptional tree care to multiple individuals across the DFW area with absolutelys sterling results. My clients turn to me with trust and I never have to hesitate when im asked who to call for any assistance in the realm of tree services. Aspen is the name! Along with myself (a climbing arborist practicing for over 10 years) Every single one of the dozen or so clients that I have brought to Aspen since partnering with them has each been especially pleased with the quality of service and the care and attention to detail provided by the crew. Weather im on site to supervise or not, they have always taken immaculate care of any referals ive sent their way. They have a vastly talented and well experienced crew that really understands how to get the job done right and in a way that makes Aspen the only name a customer needs to know in the tree service industry. They will be ready at the call for any tree service needs from massive emergency removals all the way across the spectrum to a full menu of plant health care services. You will not regret doing business with Aspen. Don't hesitate to call for a free estimate or with any questions as to what services they offer.
Aaron and his crew did an amazing job coming out and cleaning up my overgrown trees. His crew came in and had all 3 trees done in 2 hours.
This company was great! They came to treat trees that were infested with the fall web worms and did a thorough job in examining trees and explaining causes and treatment. The technician, Mike, was very knowledgeable, experienced, and professional to work with. Highly recommend.
Aj and his crew were fantastic. They were on time as promised. The price estimated was very fair and was actually a little cheaper than originally estimated. The crew did everything that was estimated and then some. When the work was completed Aj walked the project with me to make sure that I was happy and pleased with their work. I believe this is the 6th job that Aspen Tree Service has done for me and we are always pleased. We will of course use Aj and his team in the future and we would definitely recommend him on any tree job you might have.
WOW! What a group of Pro’s. They did a terrific job. We could not have been more pleased. They cleaned up EVERYTHING, and they called the next day to make certain we were pleased. I would definitely refer them to my friends. And they’re Certified Arborists as well! They know their stuff.
Tim was great. Very knowledgeable and answered all my questions. Very prompt too.I didn’t make it home in time to watch the crew but they were in and out in a couple hours. Did a great job on my front, side and backyard trees.The best part, they didn’t leave a trace that they were there - the yard was super clean! I wouldn’t have minded having the pile out front for a couple days either. The crew lead texted me when they were on their way and corresponded my ETA even though I didn’t make it in time. LOLHighly recommend and will be using them again in the next year or so.
We highly recommend this company and their team of experts. Service and estimate was supportive and honest, the crew was thorough and careful with a challenging job, and clean up was superior. Very professional and did an excellent job with tree trimming, pruning, and large limb removals.
Great work from friendly and professional people
