I have read many conflicting resources on overwintering palms in the lowermainland fraser valley area. Some say no protection is required at all, while others paint a much more distructive picture of our winter climate on outdoor palms. This is what i have gathered. In the last 6 years abbotsfords coldest temperatures have been fairly mild. Winter 01/02 the min temp recorded was above -5c. Whereas last winter we recieved our coldest night in the last 6 years being -12C. That being said our coldest nighttime low in the last years has only been 10F. To me that would appear to me more of a zone 8 than zone 7 like most people rate us. I do agree, however, the wind factor can be the tip of the iceburg. bearing that in mind, what should be done to mediterranean fan palms outside in our climate? should they simply get wrapped on the coldest nights with burlap, or are more creative means required. I would love to try to come to quassi conclusion on the matter.
