🌱 How to Care for Noble Dendrobium to Prevent Thrips?

💧 How to Water

Water thoroughly once a week during the growing season (spring-summer), allowing the mix to almost dry between waterings. Reduce watering significantly in fall and winter, just enough to prevent canes from shriveling. Resume normal watering when flower buds appear.
