🌞 your cactus will grow best in bright, indirect light! If the "Mermaid Tail" starts to show discoloration, it may be receiving too much light.
💧water sparingly - wait for the soil to dry out completely in-between waterings. In winter, water even less frequently as soil will take longer to dry out.
🐶 although this cactus is non-toxic to cats and dogs, the spines can cause irritation or upset.
