|What is the best way to cover small fruit trees to prevent damage from Arizona's mild overnight freezes? Is a sheet enough or should I buy something else like a tarp or even a little further like the Planket (http://www.theplanket.com/)
|Citrus trees can usually tolerate a light frost; other tropical fruits might not fare so well. To answer all your questions about frost protection, visit the following website which is sponsored by Arizona State University. It has tons of information and since it is a PDF file, you can print it off for future reference: http://cals.arizona.edu/pubs/g...
Best wishes with your fruit trees.
