The last couple of years I have winterized my minibog by cutting all the Sarrs except the Purpureas down to nubs. Then putting a sheet of card board over them. I then cover that with two bales of straw. And then another sheet of cardboard over the bales to keep them dry. I assume dry bales will insulate better.
This is my first bog and I made it using the rigid liner from a ½ whiskey barrel. I was thinking that since I now have an unused wooden ½ barrel lying around. I could invert it over my bog, and then cover it with loose straw. Picture a small hay stack. I would then cover this with a tarp to once again keep the straw dry and hopefully fluffy and insulating.
My hope is that by doing this I would not have to cut the Sarrs back. It seems like they should start out stronger next year. But it may not be warm enough. I am in Central Ohio zone 5B.
So am I ?
