I have come up with a measure to keep or remove Palms (and other Tropicals)in my garden. Each one that gets 3 stikes against it from freezes are coming out. 1 strike will be awarded to the plant that receives 60 - 80% damage. 2 strikes are awarded to plants that receives 80% and above. On a no damage year a stike will be removed. What do you think? Example this Royal would receive 2 strikes from the 2009-10 winter.
