Manganese sulfate for withering sago
Our sago's new leaves have what I've discovered is called "frizzle top". The new leaves are curling and spots of it are turning brown. They say to spray the leaves with manganese sulfate, and fertilize with such. We put in Jobe's palm fertilizer spikes this past weekend.
I am trying to find manganese sulfate to mix and spray on the leaves and only find it on alpha chemicals and it says it is only 32% mn. Is this okay? I can't seem to find it anywhere else. Would I just mix 3x the amount because it's such little manganese concentration?
Thanks for any help. I want to get my poor little sago back to health, it's only been in the ground for a few months! Thank you all!
