Tropical milkweed number of simutaneous cuttings per stem
Tropical Milkweed, one growing stem, 18 - 24" long :
Can it be used as three rootable 6 - 8" cuttings?
(either all cut within minutes, or spaced over the course of a day, if delay should offer some benefit).
I have never tried using one branch for several cuttings, but I see no reason you couldn't do this. You should be able to cut all at once - I see no benefit to delay.
Make sure there are several buds on each stem where the new branches can grow. Hope this helps.
