I am in hot, hot Phoenix. I have been putting a light shade over my dwarf valencia and tri….something (of course I can't remember the name now!) juice orange trees. I had been getting yellowed leaves in hot weather that I was told was sun scald.

The trees are getting bigger and I would like to stop doing this if sun scald won't do a lot of damage to the tree and/or its fruit production.

I water deeply with a drizzle overnight weekly. Would more water help with this?

What say you?
