The hard part of sewing is remembering how to thread the top of the machine, and to fill and route the bobbin thread.  It doesn't need heavy thread.
With polyethylene mesh fabric, I would suggest a straight stitch at about 8 stitches per inch, with the tag extending into the bag. Only one line of stitches. Then turn inside out. If you overstitch it, the PE fabric may break. If it stretches on the plant, it may break—so make it a generous size.
