I agree - no need to include instructions. When I'm typing up my labels, if I have what look like good instructions from the vendor on online, I'll copy it into the labels.
Those labels are also my notes to myself about each variety.,
This year I thought the ground cherries deserved as much information as I could find, so I went hunting and squeezed as much info as I could onto that label.
But if I had to write it out longhand, NO WAY I would try to write more than the name and year, and my name. My handwriting is BAD!
