Pete,
Thanks for the updated observations and photos. Your trees look terrific, and look at the new, healthy, growth on that stem! Am I correct....are these before and after photos? Nice results!
My trees continue to have healthy looking leaves with no visible signs of rust, despite the humid, rainy, weather. The texture of the leaves remains thick, tough, leathery, dark-green, and not paper-thin. I don't know what it does, but it seems to do something good for the fig trees.
I wonder if this iron "tonic" supplement, will help virus-compromised trees, and delay the onset of rust infections?
In my case, I have to say that after only a few iron treatments, my trees never looked better. Not very scientific, but it is what it is.
I will definitely start next season with the iron supplements, along with the organic ESPOMA fertilizers, and, Kelp Meal.
Continued good luck, and thanks for adding to our knowledge. Any, and all, observations, help.
Frank
