The diameter is the distance across the middle of the tree. But as you discussed diameter, you actually measured the circumference of the tree in the video to decide how much growth regulator to add. Did you calulate the diameter? Or use the wrong number to decide how much growth regulator to add?
They used a specific measuring device called a DBH tape, which is intended to be wrapped around the circumference of a tree but is marked to calculate the diameter. If they had used a normal tape measuring device, you're absolutely correct that they'd be only measuring the circumference.
