I have been using Glass Tree Care for about 6 years. They are prompt, they clean up after themselves, and they always leave an invoice on my door. I don't have to think about when the next application is due because it is all in the computer. Sometimes they call the night before but generally not because I trust them.
I have compared prices, and they are in a very competitive range. I don't feel like I am getting taken advantage of. They are very dependable and honest. I would encourage people to search and find what works best for them, but certainly give Glass Tree Care a chance to look into your yard; they are very fair.
Their work is great. People stop and ask who takes care of my yard. I do a lot of my yard care, but Glass Tree Care does the application to keep it green and weed free, keep the trees healthy, and the fruit from molding. Our fruit has been great, so they have timed it right, and it works for us. It is a wet area, so it is hard keeping the fruit from getting mildew.
