Question
How to start a cutting from yellow banks rose

Answer
Take the cuttings off the rose when it is cool in the morning. Take a few cuttings because some will not strike. Then follow these directions on this webpage and Lady Banks rose will grow quite easily from cuttings. Keep the cuttings in a pot for a year until they make nice strong roots and then plant them out in the spring.
