What our tools say
How fast it grows and how big it gets, by site Whether it suits your zone, sun and soil How far from a house, wires and a septic field What grows with it in the wild and in a yard When to plant it where you live When it sheds pollen and bears cones, month by month How to sow its seed, with dates for your place Whether one you have can be moved, and what the move takes How old one is, from its trunk How a big one scores against the champion trees
