I had a plan (I hadn’t even been drinking) for over wintering my Bananas. I’m sure there are some here with enough brain cells to show me the folly of my plan. Here goes!
1. After the first frost burns the leaves, trim them back to the Pstem
2. Wrap the Pstem with two strands of mini incandescent Christmas lights
3. Plug the lights into a thermostatic outlet. On at 35 Off at 45
Greenhouse Controls - Thermostat Controllers from ACF Greenhouses
4. Plug the outlet into an extension cord and secure to Pstem one foot off the ground
5. Sleeve the Pstem with HVAC round duct work and seal at top.
EDIT HVAC is insulated and internally wrapped tp protect it from humidity
6. Wrap everything in visqueen sealing the top and bottom.
7. Place several bags of leaves around base to stabilize
8. Plug in extension cord and wait for spring
OK that’s it. Go ahead and fire away. I’d really appreciate the brutality and bluntness of your comments since this isn’t exactly cheap.
The duct work comes in 20’ lengths and diameters of 8”, 10” and 12”. Maybe bigger but that should get most Pstems.
You could daisy chain the lights to protect multiple Pstems just be sure the thermostat is on the smallest one your protecting.
Why am I doing this? I want the fastest regrowth possible which should result in earlier bloom development. I mainly want to do this on my larger ones (Pstems of seven foot and up). I believe that I can have fruit every year by doing this.
