Follow this steps to plant the rose:
First, you have to remove all the leaves from the stem. Cut it at an angle of 45 degrees. Take the potato and make a hole in it with the stem and then shove it in. It has to be fixed well, so it won’t move. Fill 2/3 of the pot with soil and put the potatoes in. Then cover the potatoes with soil and make sure that the soil surrounds the rose.
