🌱 How to Care for Dalmatian Bellflower to Prevent Whiteflies?

💧 How to Water

Water every 2-3 days during spring and summer, allowing the top layer of soil to partially dry out between waterings. Avoid waterlogging the roots, as excess moisture can cause fungal root rot. Reduce watering significantly in autumn and winter.
