Has anyone grown hybrid poplars? I've just been looking into them online and some of the info sounds interesting. One idea for them that really intrigued me was this concept of planting them like 600 trees to the acre as cuttings. Then after two years you harvest one fifth (120) of them on the southern side which gives light to the next batch north. Then the next year you harvest the next northerly 120 and so on and by the time you get to the end of the acre you are harvesting 6 inch diameter trees which would provide a significant amount of firewood. And then you start over at the other end of the plantation which has resprouted from the roots and has large diameter trees growing there again. Has anyone done anything like this? The guy who wrote this said that while poplar is soft and doesn't have the heating quality that ash or hickory do it is more than made up for by it's fast growth and regrowth potential. What do you think? It seems like a nice way to get reliable firewood while leaving the regular woodlot for wildlife and growing more valuable wood.
