I have two 100-year-old trees in my backyard and A Small World Tree Co was here recently to thin them out. We have to keep pruning them and hopefully not too much because we don't want to injure them. so it's been done very carefully and we did it in two steps. I've worked with them for years and I'm very satisfied with what they do. The pricing is not exorbitant and they're very friendly and very accommodating.
