I saw this cool idea for garden plant markers, use the slats of broken blinds, cut into long enough strips and write the plant name.
Yes, that is a great idea. I have been using the slats from a broken blind for a few years now. I can tell you that a normal Sharpie marker will fade and/or wash away outside in the weather before the summer is over. At least, mine did.
This year I bought some Sharpie Oil-Based Paint Markers which are supposed to be sun and water resistant. They have good reviews for use on plant markers. I have been marking all my plant blind slats this year with the Sharpie Oil Marker. I don't know yet how well they will hold up outside over the summer, but they are certainly much darker and look more permanent on the plastic blind slat plant tags than the normal Sharpie markers.
