Cold Hardy Citrus / Re: List of citrus hybrid that would go dormant in winter?
« on: January 06, 2019, 03:27:36 PM »
Trees that don't go dormant in winter will usually go frozen because of the water inside the tree trunk. I am not sure if it's gonna work if we use dark color water-base paint to cover the tree trunk on winter, as well as using a clear plastic bag to cover the entire canopy on coldest nights and days. As far as I know if we cover the entire canopy by a clear plastic bag, the temperature inside and outside of that bag will be at least 10 degrees in difference provided that the freezing won't last for too many days.
We can also add a light bulb to ensure, but I think if we plant our citrus trees against the southern or Eastern wall of the house, they will be okay. Someone has tried this method and their lemon tree made it through many winter in zone 6a.
Oh I forgot about the rootstock. If we use Poncirus Trilofliate we don't have to worry about the root if it was old enough. I think we better use the FD Poncirus to reduce the size of our citrus tree. Don't worry too much about those discourage you not to grow citrus at your zone. No one has the right to kill your hobby. Go for it. Do experiment and experience it yourself.
