I briefly mentioned this technique in another post, but I wanted to throw up a picture for visual-learner types (like me!). This is a great way not to waste money on those silly little plastic plant labels that you buy at nurseries:
Take a 1 quart plastic yogurt container and make vertical cuts about 3/4″ apart all the way to the bottom. [pictured below]

Then make a cut all around the base of the container, snipping off each tab. You can cut them to whatever size is appropriate for the pot they’re going into, and they’re easy to write on with a permanent marker, or better yet a grease pen or crayon (more UV and rain resistant).
Ta-da!:

Labeling vegetable starts with the variety and planting date is especially important if you plant more than one variety of a single crop. It also helps you track days until germination, germination rates, and other information that can give you useful feedback about your seed-starting habits.

Awesome tip! I never would’ve thought of this. Thanks
An even better idea is to cut up mini blinds that people are throwing away. The vinyl ones hold sharpie pen pretty well.
