How successful would I be if I left my blueberry pots outside all winter? I’m in 6A/7B. The low here in the winter is like 5 degrees. I can’t bury them, so I’m worried about the roots. Will they die?
I’m wondering if I’ll need to mulch around the pots for insulation.
I left my potted sea berry outside this past winter cover with a frost blanket. I found only a empty pot left this spring and nice cozy somebody’s straw home nearby! I think either the wabbits or vole had the tree for breakfast, lunch and dinner.
They should be fine, but adding an insulating layer of leaves or straw around the pots is a good safeguard. I’m in 7B, and my potted blueberries (an assortment of SHB, NHB, and rabbiteyes) have done fine even when I haven’t bothered to insulate the pots with leaves.
Good to hear. I think I’m gonna put all my blueberries in pots. Had them in a raised bed, but I think this is a better route for my limited space. Now to decide what to put in the raised bed… It’s 20 feet long, 4 feet wide.
Ross,
Do you mean to say 6a/6b? 6a/7b is quite a range.
If it is 6 a without micro climate, I would be worried. Like others say, with insulation, protection, should be doable. It may also depend on the varieties, too. Some are hardier than others.
I leave potted blueberries out in 6a with no problems. Even in the terrible winter of 2014/15 they were fine. It’s the constant need for summer watering that gets mine.
Does anyone else have any more advice on leaving pots outside for the winter? I am planning on leaving about a dozen fruit trees outside in pots over the winter in zone 6A. They are currently in grow bags. 10 gallon size each. I have them bunched up together but I’m wondering what kind of mulch or covering to use to help protect the pots. I predict winter lows of around -10 degrees Fahrenheit or so.
