Adam my thought that my pot was about 30 gallosn was based on the nursery selling me what they call 7 gallon size trees in containers that are at least 3 times smaller than the container my jab is now in. also, the container your 15 gallon sap, that you posted seems substantially smaller than my jab container. still, unlike you, im not a container size expert so i fully allow that i may be way off base. as soon as i get back to ny, i will try and see if the size is written on the container- otherwise, Ill measure dimensions.
