On November 17th I did my winter storage for the trees. It is my tradition since few years. On that date we have holiday celebrating end of the communist rule in our country in 1989. Now we have freedom, even if we still have to fight for it and communist are back in different furs.
Anyway, I put all my trees down from shelves and cover them with wood chips, sawdust. Cheap and effective. After that I ordered additional winter cover and watering. It arrived tonight.
