Aerosol salt? Sorry for my bad handwriting. It should be Alkaline soil - salt damage. BonheAccording to your chart, the most likely thing is pollution or aerosol salts. What are aerosol salts?
No problem Fredtruck.Thanks. I appreciate the correction.
Hi Dan, you may be right. However this small cork pine wasn't in full sun all day.This looks like sunburn to me ,are your small pines in full sun all day? I get the same thing on my small JBP,they can't be in full sun all day...even if you water all day...Today it's around 100 degrees here in the Los Angeles area. I put mine under shade cloth, when it gets real hot...like it has been this week
good luck....Dan
