All "Pine Trees" are not created equal!
Some species are fast growing and tall; others are very slow growing and
take forever to grow tall. And ALL of them can be *pruned* to slow their
growth and assure a full and well-rounded canopy.

Do a Google.com search using the exact species of tree you planted -
you'll learn all about THAT Three's growth patternas and pruning needs.
