We needed to have a tree near our driveway cut down. Another tree in our front yard needed trimming (had probably never been done). Mark came to give an estimate. We were impressed with his knowledge, preparation, notebook of pictures and description of what would be done. Customer Service is TOPS! Professional work is completed with great care and with Arborist knowledge. All areas of work were properly cleaned up. Mark told us about Enviro Tree and showed pictures of dramatic difference to trees and grass. (He 'COULD' do the application, he told us, however, he also said it would be easy enough for us to do.) We are pleased that we decided to make the purchase! Our tree is now a beautiful deep green color. We knew before that some nutrient was missing, because the leaves did not look healthy. An area of our grass that always has continual sun, is also looking much better and will improve with each application. We have purchased Enviro Tree again and will always continue to use it in our yard for beautiful trees and lawn. We highly recommend Mortensen Tree Service!!! P & K Johnson
