Starting a mandevilla plant from nodules on roots
I divided a couple of my mandevilla plants this spring successfully. However, there were a lot of nodules attached to the roots that I did not transplant with the divisions. I tried to start more plants from these by putting them in pots of potting soil. They have not been successful. Can this not be done? Thanks.

Mandevilla can be propagated by layering or dividing the root-ball; however, most new plants are produced from softwood cuttings taken in early spring.
