My question is in two parts. I had a haphazard ROS hedge between us and the neighbors house. Last year I pruned, weeded and move plants to organize it. This all happened late winter and very early spring. I got many plants that flowered wonderfully last summer/fall. But a couple of the larger plants produced large buds that never opened. Should I prune these off before the upcoming growing season? Also how should I feed these plants, my soil is fairly sandy and drains well. I the summer they get good sun in the early Am and after maybe 4pm until sunset.
