I have saved toilet paper rolls and paper towel rolls for the garden and other stuff. I especeially like to use them for helping to organize extension cords.
What you do is cut off a piece of the stem, making sure to have a joint or two. Pick off the lower leaves, and keep around 3 to 5 leaves at the top. Use some root powder as directed, and put the stem into a pot filled with rooting medium. Keep it moist but not drenched, and new roots will grow.
I just copied your info. on getting a cutting, BUT WHAT IS ROOT POWDER? I need to read that info. again, must have missed that part. I've been copying, pasting, and printing today, plus I wrote a paper explaining why all males and females act like they do - that took a little time.
About the cutting: After I do the cut and use the powder whatever that is (and how do you use it by the way), and put it in the medium, WHERE DO I PUT IT? Do I need to wait to do this until it is warm outside and then leave it outside? I don't have a sunny window in this townhouse.
I know I ask specific questions, but that way I don't screw up.
