Hi @janelle1 

Looks like woolly aphid or mealy bug to me.  Either way an application of pyrethrum insecticide or a horticultural oil like white oil or Eco oil applied according to label directions and with particular attention to the back of the leaves should fix the problem. Check every 7-10 days for further incursions and reapply if required.

Many thanks for your advice. I appreciate it and will try as you suggest

Agree qith previous comnent. Focus on back of foliage as well.
