I have been developing a spray schedule for my apple trees this year. In my 
research, I have come across several university extension sites that 
recommend dormant oil spray, bordeaux spray, or both at this time of the 
year. I am curious what other people think about which option to choose. 
Also, if doing both bordeaux and dormant oil, which would you apply first? 
Are there temperature restrictions for bordeaux spray? The trees in question 
are in Zone 5A.
