Rose Balling

Rose balling Common name Rose balling Causal agent Rose balling is a physiological disorder that occurs during wet, shady conditions. The wet weather saturates the outer petals, while sunshine dries the petals, preventing bud opening. Hence, rain, shady conditions, and low temperatures are responsible for the balling effect. It usually occurs in fully-developed buds of double flowers. Symptoms & Signs The petals initially turn soft and mushy due to wet conditions and later on turn crisp and brown when the petals dry. It may occur only on the outer petals of the double-flowers, while the inner petals remain normal. The bud fails to bloom, either hanging on the plant or falling off. Buds that do not open and continue to hang on the plant may show signs of grey mold. Time of concern Spring and summer Common hosts Roses Peonies Camellias
