Is it overwatering or manganese deficiency? I fertilized last week with Carl Pool slow release palm food. First one was in April. Is it possible that because of all the watering that they have needed the "slow release" has been accelerated? But Carl Pool has magnesium and extra manganese as part of its formula. 4 different plants different ages in separate pots all showing light yellowing at the same time. Has to be something I'm doing does it not?

Hey S-

I would give them some Epsom Salt diluted in water...1 tablespoon per gallon. See if that helps and then let them dry out between watering. Is that the way you water your Sago's? You can always sprinkle ES around the outer part of the pot, but if they are in need of Mg. then I would give them a diluted dose so they can absorb it faster.

Hope this helps!!!

Your yard is beautiful...I love the layout of the pool!!!

Thanks Laura, I thought of epson salts too. It has been so hot here I did not think I was over watering but that has to be it doesn't it?
