So I used an ounce to 1 qt water. Seemed a Lil heavy very dark. Would cutting that in half defeat the purpose? I used all but maybe 1/8th of it. So sprayed the rest on my Korean dogwood tree it's having major issues anyhow.
So roughly 1 qt of DeStress took care of 12 1 gallon plants and 6 7 gallon plants.
thats about right...I just had the same result.
