25-Pack Systemic Insecticide Tree Implants for Control of Tree Pests, 3/8-Inch

My tree is over 40 years old. Two other neighbors are and have lost the same type of tree. Being in AZ. I wanted to see if I could save my tree in order to keep my shade. After researching what would be most helpful, I was unable to find a local seller. The other items guidelines were to pour a liquid at the dripline. Common sense to me said that was not going to reach the tree roots. Drilling into the bark made more sense. I did have to use gauze to wrap around the tree to hold the pellets in place. We have cut all the dead branches off and drilled holes at the drip line to give the tree fertilizer. Thankfully we had some rains that helped. I treated the tree in July, and it is now Oct. I have seen some new growth, which I am praying that the tree can come back. When I tried to purchase the item locally, I was told the product is good but new items come on the market and people think the new product is better. He was sure that people would once again request it so that they would stock it again. Wish you the best on saving your tree. If my tree does not die in the next year, I will let you know.
