Question
My family lives on a small farm and my boys would like to earn some extra money.  They want to sell Christmas trees in a few years and they were wondering when is the best time to propagate the selected trees.

Answer
Hi Andy,
Thanx for your question.  I am not a tree expert.  We have one here on Allexperts named Jim Hyland.  He can be accessed by going back to Home/Garden and then clicking on Trees and then clicking on Trees again.  I do know there are a variety of different trees and some are more popular than others depending upon which part of the country you're located.  

Here is the website for the National Christmas Tree Association where you should be able to find lots of helpful information for getting started.

I hope this helps.
