Kalanchoe Blossfeldiana (Calandiva) in Indonesia: More Sun, More Water, Fertilizer 1:3:1, Alcohol for Spider Mites, Avoid Full Sun If Too Hot

Core Issues

• More sun & water: Water until all soil moist, empty saucer 1 hr later. Water again when pot feels dry & light (compare to dry soil pot).
• Sun: As much as possible. If full sun burns, use dappled or morning/evening sun.
• Fertilizer: 1:3:1 or any bloom formula. Add CaO/Mg(OH)₂ at half label strength.
• Spider mites: Prefer 70% rubbing alcohol (straight or 3:1 with water). Second choice: 1 tbsp liquid soap per liter water + neem oil for residual effect.
• Repotting stress: 2–3 repots in a week caused yellow/curling leaves. Stop; use pot weight method.

Outdoor night temperature drop benefits them.
