I have left the lemon tree out in the weather this year, possible the worst year in a very long time. If it survives this I will have no worry about planting it anywhere around the house. It's been frozen to the point that if it was going to die it would.
When everything else had snow and ice on it, the lemon tree didn't have any. I figure it has to do something about the oils in the leaves repelling water. Earlier today the leaves were still green and just a little curled.
