  • Overwatering

    Yellow mushy leaves mean reduce water immediately.

  • Cactus Spines

    Use folded newspaper or silicone tongs — never bare hands.

  • Fertilizer

    Dilute to quarter strength — enclosed roots cannot flush excess salts.

Safety Notes

  • Cacti spines cause skin irritation — wear eye protection when planting.
  • Sterilize tools between plants to prevent pest spread.
