💡 Care Tips

Key Care Instructions **Light:** Prefers soft, diffused light; avoid harsh, direct sunlight. Provide diffused light in spring and autumn, but ensure shade in summer. In autumn, limiting light exposure to 8–10 hours a day—followed by complete darkness—significantly promotes bud formation. In winter, place on a south-facing balcony to maximize sunlight, which aids flowering and cold resistance. **Temperature:** The optimal growth temperature is 15–25°C. Growth stalls below 10°C, and cold damage occurs below 5°C. Temperatures above 30°C trigger semi-dormancy; move the plant to a cool, well-ventilated area. **Watering:** Follow the "water thoroughly only when completely dry" rule; err on the side of dryness rather than excess moisture. Its fleshy stems store water, so overwatering easily leads to root rot. Check moisture by inserting a finger 2–3 cm into the soil or lifting the pot to see if it feels significantly lighter. Water along the edge of the pot; avoid getting water into the stem joints or the center of the plant. **Fertilization:** During the growing season (spring and autumn), apply a diluted compound fertilizer once a month. In the budding stage (late autumn), supplement with potassium dihydrogen phosphate via foliar spray or soil drenching every 10 days. Stop fertilizing completely during the flowering period and summer dormancy. **Soil:** Requires loose, well-draining, slightly acidic sandy soil. Recommended mix: 4 parts leaf mold, 3 parts peat moss, 2 parts perlite, and 1 part vermiculite; alternatively, use a specialized cactus potting mix. Choose a shallow clay pot; avoid deep pots or non-breathable glazed ceramic pots.
