Has anyone tried to grow avocados in Las Vegas? I was discouraged to do so by a reputable california grower. His reason was that the winter's frost here would probably kill the tree. I'd like to try it anyway and see if covering them during the frost might eliminate that problem. Would I have to cover the whole tree or just wrap the trunk as in the case of a palm tree? Not really wanting to move them in for the winter. Any suggestion on types and cross polination? Thanks all! Also considering persimom trees.
There was discussion of this last year on the forums: http://www.botanicalgarden.ubc.ca/forums/showthread.php?threadid=8842 http://www.botanicalgarden.ubc.ca/forums/showthread.php?t=9041&highlight=avocado We actually tried two cultivars in the Food Garden at UBCBG last year, 'Mexicola Grande' and 'Stuart Mexicola'. Last winter's weather was very rough on plants here and the two little trees, which had both been planted late in the season, died overwinter. Might have been better to plant in the spring. You may have luck in Las Vegas (Zone 7?). The much drier climate and briefer periods of cold may be tolerated with protection. The summer heat would certainly do them better than Vancouver's maritime cool summers. Let us know if you are able to push the boundaries. Good luck.
I'd think drying winds and mineral salts in irrigation water might be a problem for them in the Nevada desert. Yes: tender shrubs should be planted in spring instead of fall.
Jeff: Arkansas Black and Pink Lady apples do quite well in the heat of Las Vegas. The quality of both is excellent in a hot climate. Applenut
