I use surveyor's tape in the green color if I can find it. I have a large stash of
yarn from my knitting days, so I use the yarn to tie the tags on the pod.
Not necessarily my favored materials to use, but it uses up what I have on hand.
I write both pod and pollen on tag, and the date it was crossed, and if it was
crossed at an odd time of day, then I also put the time.
This year I had to cut off the scapes before the pods were ripe, and thought it might
not work out, but lo and behold, they worked just fine. I put the scapes in vases
of water in front of an east facing window.
