beemeupscoty,
Have you grown trees before?
The reason I ask, is I briefly looked into this awhile back. Seems weed suppression or control is but one concern. From what I was told, yearly spraying may be needed for a whole host of potential problems. And since trees are planted every 6 -8 foot apart, disease and spread is a concern. 5-7 years of time and investment is much to find out your trees are sick if no control measures are applied.
I'm no expect on the subject. But I found out that my "Plant the trees, wait 7 years, and collect the money....was a bit foolhearty." Much more go into it.
