As part of a major cost reduction project, I'm using disposable knives, cheaper than the pot labels at the garden center. If I had been clever(er?), I would have used knives for the day lilies, spoons for the tulips and forks for the irises, thus saving wear and tear on my marker pen.
and you could remember the shapes? I'd have to refer back to something to jog my memory of which was which lol. they look to be biodegradable too...bravo!
