Donald in Calgary

My weeping birch tree was badly attacked this spring, again, by leaf miner. My usual arborist, who I have been happy with, drills holes around the trunk and inserts insecticide pellets. After that is done, I have to run the water on the tree for at least an hour. With the watering restrictions in place, that was not possible this year. So I called Mathew at A1 and asked if they had some other method of dealing with this blight. He responded that his company does tree injections that do not require extensive watering afterward. So, he sent out Andrew the next day to give me a quote. I accepted, and Andrew did the injections right then and there. I am happy that they were able to respond so quickly, given that I should have acted a week or two earlier. I hope that the injections shall be effective at arresting the advance of the leaf miners.
