Rose Stems Started Sprouting in My Vase

Plant them in a potato. If you live where it is warm enough, plant outside. Otherwise, keep indoors until you can transplant.

I didn't realize that you could get roses from cuttings but apparently it is possible

they suggest adding a rooting hormone such as this

FAST ROOT :goo.gl/ilWP4q

they also say that the rose that will emerge is a clone of the original plant

Hi,

I am happy that your rose started to grow! However you plan to plant your rose, you can use honey as a rooting harmone ;)

Blessings,
