A generous nafexer donated a couple hundred grow tubes to our tree growing
efforts here. Actually they are recycled tubes from some industrial
application, heavy wall, translucent plastic 5" x 2'.
I have been told it is not a good idea to leave them on even year old whips
through the dormanting season, because they will not harden off as well as
if they had been fully exposed to the oncoming winter.
Snow and low 20'sF is the forcast here this week.
However, I have such a vole chewing problem that I am tempted to leave them
on. I eventually depend on window screen for vole protection, but doubt I
can get a couple hundred screen tubes in place by freeze-up this fall.
I'd like some opinions from folk out there on the subject of grow tubes and
achieving full dormancy, or other winter concerns, thanks!, Del
