George:
I like your idea of placing the trial label stock on actual use pots with plants in them. I will be starting my Tuberous Begonias soon, after the danger of frost is over. Putting labels on them would certainly put the 'pedal to the metal'. Watering, fertilizing, sun-shine, rain (no snow I hope), even the pots rubbing against each other will make good tests.
What are the your pots made of - ceramic, terra cotta, fiberglass, resin, wood? Any more suggestions, you guys?
