Blossoming Questions

Hi purchased beginning of may and the shrub has a couple of full grown roses. We had a late spring frost and ever since the roses that do bloom currently are small and petals just fal right off. Is this normal?
I didn’t prune my Endless Summer last fall or this Spring. I am getting new growth on almost all of my stems. Can I NOW cut some of the stems back to a new growth? It seems when I think about doing that and look at them I see more growth popping up further up the stems almost to the top.
I NEEDED TO REMOVE TWO LARGE PURPLE-LEAVED BUSHES FROM ALONG THE WALL OF THE SOUTHERN FACING SIDE OF OUR HOME. THEY WERE PLANTED ON OPPOSITE SIDES OF A LARGE SILVER-LEAVED WHITE POM POM BUSH. THE REMOVED DYING BUSHES WERE APPROXIMATELY 10 ‘ TALL AND 15’ WIDE. I’D LIKE TO REPLACE THEM WITH SOME TYPE OF SHORT EVERGREEN PAIRED WITH SPRING/SUMMER LONG BLOOMERS. I HAVE IRIS, PEONIES, AND HOSTA PLANTED ALONG THE PERIMETER OF THE GARDEN. ROSES DO NOT DO WELL FOR ME. THANKS FOR ANY HELP!!
I BOUGHT THIS ENDLESS SUMMER LAST WEEK. THE LEAVES TURNED BROWN AND SOFT. I’M NOT SURE WHAT HAPPENED. IS IT BECAUSE OF THE WEATHER? LAST FEW DAYS IT SNOWED IN OUR AREA. THE TEMPERATURE DROPPED TO -2 DEGREES AND SPRING SEASON IS ALMOST OVER.
ONLY 1 OF 4 PLANTS BLOOMED LAST SUMMER. THIS SPRING I HAVE GREEN BUDS AT GROUND LEVEL BUT NOT ON LAST YEAR’S WOODY STEMS. THE BUDS ON THE OLD STEMS ARE BROWN AND APPEAR TO BE DEAD. SHOULD I CUT THE OLD STEMS TO THE GROUND? HALFWAY? WHAT AM I DOING WRONG?
Should Limoncello Barberry be pruned to the ground or just the top third next spring?
The leaves on my rose are getting spotty. What does it need?
