What would the diameter of a birch tree be in 30 years if I planted a clump of two or three this spring? Would they last that long or is there a better tree to plant? Thanks for your help. Gary Frederickson

The average Paper Birch (I am assuming this is the birch tree you are talking about) lives around 100 years in forested conditions. They tend not to live longer than 30-40 years in lawn environments. On average, their circumference would be 8 inches after 30 years with a maximum average circumference of 10-12 inches per the US Forestry Service.
