Rose Cuttings: This is crazy! I LOVE Roses and plant them wherever I live!!!! I'll be doing this! Did you know that you can grow roses from cuttings? Simply cut healthy stems, place them in large potatoes, and them bury them 3-4 inches deep in a healthy soil mixture of peet moss and top soil. The potatoes keep the stems moist and help develop the root systems. It's a perfectly simple way to multiply your rose garden without spending lots of $$$.
