These plant pins were new to me, and easily solves the problem of how to pin short or non-existing vines to a medium when trying to root a non-ideal cutting. I have no idea where you can find these as they were sent to me by my great Hoya friend Mandy Lin. I want to thank her personally for this great invention and for the Hoya papaschonii seeds she sent me! Below you can see the pins and how I immediately put them to work.
