I am also interested to get some information about growing green tree farm. As I mentioned on the top I have 3 acres of property which is some area is trees but I want to get rid of them and clean and raise a green tree farm either christmas trees or pine trees or any green trees that doesnt require maintenance and also looks cleaner. How much it costs and where and when do I start? Can I do that? Please advise.
thank you for your help pl.

The best way to control weeds is the old fashioned way-shallow cultivation. There is a pre-emergent herbicide called Treflan or Preen that provides 6-8 weeks of control in established flower beds. It is applied in spring and throughout the growing season. It prevents dormant seed from germinating but will not kill any existing weeds. There are some restrictions for use and you should follow manufacturers recommendation.
Rgarding your tree farm, contact your local extension office or your conservation district. Ask for an extension advisor and they will direct you to the person that can help you with large scale tree production.

One product out on the market is a foam, produced by Roundup called Weed & Grass Killer Sure Shot foam. This is a systemic that is absorbed by the plant and kills the whole plant. It works best in full hot sun. Wear gloves to remove the dead stems and bury them or put them in a garbage bag. Do not try to burn the debris as the smoke can also cause allergic problems. Glyposate (Roundup) also works but it will kill everything.
