Your problem may be how long the roses were without sunlight before you
bought them! Stores will keep them till they sell and without sunlight
that is bad news. Remember that winter sun has less time and power and
signals plants to go dormant. This may be your case. I say continue to
give them sun, cut back on the water (damp, not dry), let them get cold
and wait for spring.
Haven't grown Roses, well sweetheart, what folks call thorns are really
hooks that will grab you and hold on!

PS; If you lose these keep the names. You can order them in the spring
from many places on the WEB.
