Thanks Liz, Lynn and Diane.
Given that they are perennials and this will be their 3rd year in the ground, hopefully I'll get some blooms in the new year !
They were small 4" plants when I got them so this should be their year to "leap"...as the old adage says, "first they sleep, then they creep, then they leap."
I've just been using regular granulated rose food on them.
