Nothing like a test on potted plants. If anything, stuff in pots is more sensitive due to the limited root area. I test product tolerance on 1 gallon plant material or 10x20 flats if it is ground cover before unleashing something on hundreds of plants.
They who can give up essential liberty to obtain a little temporary safety, deserve neither liberty nor safety.
Benjamin Franklin 1775
Sell not virtue to purchase wealth, nor Liberty to purchase power.
Benjamin Franklin Poor Richard's Almanac1738
