Other fruit features.Tamdori is intermediate resistant to citrus scab disease, citrus canker and melanose. For the very early mature stage, Tamdori should be protected when cultured. Since the fruit would be matured in mid-February of the second year, and the cold season may reduce the quality of the fruit if the fruit is planted in open field, Tamdori needs to be planted under protected environment. Pruning on Tamdori is the same as other variety which belongs to Citrus reticulata Blanco. Fruit and plant are damaged when the temperature is below 7 C.
