I was cleaning up and found a few old pots, under my outdoor staging area. The plants were bought 4 years ago!
Attached were labels, and wonder of wonders, they were still readable.
The labels were printed with an InkJet printer, but had been put through a laminator.
Now heres another clever idea.
The laminated labels were stapled to the pots!
They were in 3in square pots, so stapling was easier than trying to staple to a round pot.
So... I'm buying a laminator.
Incidentally, the occupants of the pots have long since died.
They were very pretty little cultivars in the genus Rhodohypoxis.
I'm afraid I planted them in rich soil, and weeds choked them. I'm planning to create a small alpine bed 8ft x 6ft just outside the kitchen window and plant some more of those beauties.
