If you want to make your landscaping look fantastic, trim your trees. There are a lot of different things to consider when trimming your trees. If you were to make a mistake when trimming your tree, it could kill the tree or affect its bloom. That's why it's always best to leave your tree work to the experts in Spokane: Arborist Tree Service.
There is not a yard, park or green space that is not enhanced by the majesty of a tree, be it large or small. Keeping our trees pruned and trimmed, not only keeps them in good health and looking good, but helps protect them from pests and breakage during harsh weather conditions too. There is a difference between pruning and trimming however that one should be aware of.
All non fruit trees can be treated with Micro-injection, anytime during the growing season. If you pick an apple and notice a worm, there are a few things you can do before the tree is sprayed for worms. One thing you can do is bag the apples on the branches when they start to grow. You will also want to pick up any apples that have fallen on the ground.
There are several different signs that your tree has a disease. One of the causes of it can be Mother Nature. Things like extreme heat and extreme cold, along with wind and rain can affect your trees health. If you have a bad storm tear through your yard, you'll want to check out your trees to make sure they are still in good shape.
Are you dealing with pine beetles in your trees? The little black bugs about the size of a grain of rice make their homes in pine trees. They play a key role in the "circle of life" in the forest. They normally attack old or weak trees and make way for new and younger trees to grow in the forest. It all starts when the beetles lay eggs under the bark.

UPDATE: Derek immediately made contact with me after my initial review and the remainder of my communication was with him and he was VERY responsive, clear in his communication and was able to take a look at my trees within a couple days AND treated them for insects while there. The cost for the treatment was by far competitive and I was more than happy to use Derek, The Arborist. Thank you Derek for everything!!

Derek came and pruned my two cherry trees this year and last and did a wonderful job both years. He left the area clear of debris and was responsive to questions and was able to get me in quickly! He diagnosed and treated my distressed tree showing gummosis. Hopefully I get cherries this year!

Derek is a certified arborist. I tried contacting others with no response. I did call Senske and while i use them for all other yard service their bid was 300 more. Very pleased with the ease of scheduling and the work they did. I would highly recommend them. I also appreciated his patience with all the questions i had about my pear tree.

I tried several different companies to help me cut down a large, high cedar branch that was hanging over my main power line and only Arborist Tree Service was able to answer the call and help me take care of the issue. Derek came out within the week just to do an estimate but actually helped remove some of the branch on the spot! We agreed on a fair price and he was very friendly and easy to work with. Great service - will definitely not hesitate working with them on any of my future arborist needs!

My husband and I have used Derek to treat our trees for several years now and he is fantastic!
We live on 11 acres with several different varieties of trees that require good care and maintenance.
He has brought back numerous trees that were infested with bugs and on the verge of dying and has helped maintain their health since.
He is very fair with his pricing and doesn't price gouge us as many other companies would since we live in Elk, Washington and are a good 40 minute drive north of Spokane.
Derek is very knowledgeable in his field and I've learned quite a bit about tree health from him

I do not recommend this Arborist. He charged a HUGE fee and did 15 minutes worth of spraying. When I went out to check his work, I discovered he only sprayed the front half of the tree trunks and went up only 4’. The treatment was for needle blight on my aspen firs. When I inquired why only the front 1/2 of the trees were sprayed he became angry and said I was accusing him of not knowing his business. My husband came out and this arborist yelled at him too. We tried to explain all we wanted was information, but he would not listen and angrily left.

Derek was very knowledgeable. He was able to diagnose most of the issues my trees were having on site and that which he was unable, he researched and got back to me in a timely manner with answers. I have now used The Arborist on three different occasions. I have several properties and a list of professional contractors I trust and call on for help. I will be adding The Arborist to that list.

I had multiple companies attempt to diagnosis my tree problem with not one getting back with me with an answer. Derek knew instantly what the problem was and how to treat it. In addition he trimmed a over grown weeping birch that now looks like a piece of art in my front yard.
His customer service is exceptional. I will use his services in the future and refer to my friends and neighbors.

We contacted Arborist Tree Service to look at our young trees and offer recommendations on trimming them. Derek who is an ISA Certified Arborist was professional and very knowledgeable about pruning and overall tree health. He provided us with a fair estimate before he left. I appreciated that greatly. The day of service he was prompt and he and his team did an excellent job of cleanup. I highly recommend Arborist Tree Service if you are looking for an expert. I look forward to working with them in the years to come.

Derek and his crew did a excellent job of toping, pruning, and treating 3 mature Paper Birch trees that 7 other tree removal/treatment firms pronounced to infested with the birch bore beetle to be saved and suggested removal. It was obvious in speaking with Derek that he had a much better understanding of the problem and felt all 3 trees could be saved. Time will tell, but we are very happy with the service provided and we now have a better understanding of how to manage these trees and will be using Derek for future treatments of our birch trees, plus any other tree issues we have. We are thrilled
