"There is a book called Basics of Growing Christmas Trees by Donald B. Hilliker, Jr. from Treehaven Evergreen Nursery. We do not endorse or sell this book, but it does offer a lot of helpful information to anyone getting started. You can purchase a copy at any major nursery in your area. If they dont have it, they should be able to tell you where you could find a copy."
"In addition, growing trees varies a great deal, depending on your climate, soil, and what kind of tree species youre interested in growing. We recommend that you contact the state association closest to you. Visit our list of state and regional association contacts for assistance. NCTA membership information can also be found there."
I also recommend that you contact your State Forester or Extension Forester to find out more on growing Christmas trees.
Purchase Lewis Hill's Christmas tree growing primer as a beginning document that helps explain the ins and outs of tree farming. He may just talk you out of your dream to grow trees and get rich. Check out my review of Hill's Christmas Trees: Growing & Selling Trees, Wreaths & Greens
