I know a lot of people here in Phoenix plant out in mid-Feb, have lots of 38-40 degree nights. I don't do it, as I've seen frost in my yard those nights. I've also heard it can slow them down a bit.
To much chance of frost when the weatherman is wrong or if conditions are right. You can have frost up to 40 degrees or so. But, most times, they are fine down to low temps, no problems if not frozen.
