When I have a broken rose stem (usually a new growth stem) how do i get it to grow? I dont have any root hormone but dont want to just throw it out. The stem is about 1/2 inch thick and i think it was about to have a bud sprout at the top. Do i just stick it in the ground? Do i take leaves off? Do i cut the top part off? Please let me know. And, what about old growth stems? is it the same?
