Labels do not need to be sophisticated or artsy. They can be make from any number of materials, from tongue depressors or wooden stakes to commercial label sticks. If you prefer more imaginative labels, there are hundreds of creative and artistic plant label ideas on Pinterest and other websites. Use acrylic paint or a black permanent marker for writing the information on the label; anything else will fade in the sun and become illegible. Mark the name of the crop, the planting date, the number of days to germination, and how many days to the harvest.
