The Q&A Archives: Rose Flowers Don't Open

Question: I have a beautiful white rose bush with flowers that do not open fully. The buds are big, but the flowers only open halfway, then wilt.

Answer: This condition is most likely a physiological problem that occurs following alternating dry and wet weather, mild temperatures and cold spells. Poor nutrition can also contribute to this "balling". Give your rose some extra care by mulching the soil well to reduce soil temperature fluctuations and feeding with a high potash complete fertilizer, or phosphate rock and greensand.
