FYI - I'm planning on getting a couple of 2.5 gallon jugs of Anti-Stress 550 to apply to trees in my chestnut orchard. On days when we get over somewhere around 90F the leaves fold to conserve water due to our dry climate and it's really bad when we get over 100F. For the nominal cost, I'd like to see how this might help trees cope and increase production. The studies show that crop yields are improved, even when adequate water is available to the roots. The leaves on my bananas also show stress during hot dry conditions and I expect they would benefit from the use of the product. Folks like Scot and Paulo in even hotter/drier desert climates might get big benefits, I'm guessing.
I'm not concerned with frost damage in my chestnut orchard but will try it on my tropical plants as well as possibly on my pomegranates which do experience some tip die-back.
