From a roll of marking tape/ribbon (the type surveyors use) cut pieces 6" to 8" long (length will depend upon the side of the plant/branch you want to tag).
Using a whole punch, punch out a slit about 1 1/2" long about 1/2" up from one end of the ribbon.
Punch out "notches" a little ways up from the slit (see photo)
Using a permanent marker, write your plant name on the tag.
Loop tag around branch and slide end into slot.
