I have overhead irrigation for frost protection. I could change out microjet sprinkler heads to a higher gallons per hour head andcould possibly run it once a week for a duration to wash rinse off some powdery mildew. Is this Ludacris or plausible?

This seems like a reasonable thought..  On the other hand could it not spread it to an adjacent tree if the water is misting? I truly don't know, just considering possibilities.  Could the misters be set up for routine sulfur and/or copper application?

What I really wanted to ask you about though, is can you show me how you set up your overhead irrigation for cold protection?  I am curious of this, as I live in the 9B/10A area (W FL / Tampa) and and will soon be planting out a grove. Have about 11 trees in the ground now, but I'm usually putting lights on them or covering the smaller ones over the winter, which won't work well in the long run for a larger grove.
