need help! planting 10 autumn blaze maples
We have a unwelcomed neighbor building a home next to ours. We live on 3 acres and have about a 150 property line that we want to plant the trees on. We want to have privacy in the spring/summer and nice fall colors. We are unsure how far apart to plant them? I will thinking 15-20 feet apart but I want the trees to develop nicely, but we also want privacy.
