Tree and Shrub Feralization

Why should I fertilize my trees?

There are many reasons you should fertilize your trees and shrubs. They may need an extra boost to put on some new growth or the soil they are planted in may not provide the proper nutrients your tree needs.  


Our fertilization packages start at $115 for the average yard in Lethbridge. 

Deep Root Fertilization

With Our deep root fertilization process, we get the fertilizer where it needs to go.  You might think because you have fertilized your lawn that your trees will be good too.  In most cases, the lawn fertilizer will not make it to the roots of trees and shrubs.  We inject liquid fertilizer right into the root zone skipping grass.


Our fertilizer has been specially blended for our trees, soil, and climate. If you want to get your trees the best chance contact us today to book your fertilization.

We had Adam come over to the house to give us an estimate for pruning a 17 year old Amur Maple tree. He was prompt, professional, informative and detailed. He suggested that we should wait a few years until we hired him to have a major pruning done. He assured me that the tree was in good shape and with some minor pruning, would stay that way for a few more years. He then spent the next 20 minutes showing me where to make cuts, so that I wouldn't have to hire him for a few years. That strikes me as rare in this day and age, someone not wanting my money as fast as they can get it! All together he spent about a half hour with me offering advice on the maple and two other trees we have on the property. We have used this company in the past to remove a tree and they did a great job. I recommend them highly. Mike Byneshewsky
