How do I become a Christmas tree farmer ?
There are lots of things to learn before the first tree gets planted. Ohio State just produced a Christmas tree manual that is written for those thinking about getting into the business. It is available online at http://estore.osu-extension.org/productdetails.cfm?PC=2842 or contact your county Extension office to purchase a copy.
The other option is to talk to other growers. A list of growers here in Ohio is available online at http://ohiochristmastree.org/
