I live in Albuquerque, NM. We have cold winters and occasionally snow. Five years ago I purchased what is commonly referred to in these parts as a "Mexican Palm". It was about 5 feet tall and each winter I wrap it up in insulation and it has grown and prospered. This year, when I unwapped the Palm, I noticed a wet, soggy spot measuring about 3 in by a 12 inches on the trunk. I've been attempting to find out the problem and how to correct it. Horticulturists in this area are unable to help in the identification of the problem. The Palm tree appears healthy and is still growing. I recently dug out the area, sprayed the affected area with a fungicide and then used pruning paint to dry it out. There still appears to be some sap at the base of the affected area. Anyone have any idea as to the problem and how it might be corrected?
"Mexican Palm" is Washingtonia robusta and native to Baja California. The "California fan palm" (Washingtonia filifera) is native to the state, and SW Arizona. This is somewhat hardier and is more suitable for your location. Either way, the problem may be with your winter wrapping / insulating technique which has finally manifest itself. Most problems are evident shortly after spring weather is underway, certainly a long ways off now. A pic would help as suggested. Cheers, LPN.
Thank you for your input. Responses received to date seem to indicate the possibiliy of moisture getting behind the wrapping. As noted, we've been wrapping the palm for the past five years during the winter season. It certainly looks healthy and appears to be growing. I'll see about getting a picture this weekend and posting it for your review.
