🏝️ Habitat Conditions
This plant is found worldwide but primarily grows in America. It thrives in warm, sunny locations.
🪨 Soil Mix
When planting in the yard, ensure proper drainage to prevent water pooling. It's important to plant in well-draining soil. A common mix is 40% potting soil, 20% bark, 20% leaf mold, 10% perlite, and 10% humus. However, the ratio may vary depending on conditions and environment.
🌡️ Environment

💧 Water
This plant thrives in slightly dry soil. Water it when the inner soil dries out. In summer, when it blooms, water it when the surface soil is dry. Be careful not to get water on the flowers, as they can easily be damaged.
🌱 Propagate
Use sterilized tools to cut the stem at an angle, dry for 3-4 hours, then propagate in soil or water. 1. For water propagation, avoid transparent containers. Place the stem in water, and once roots appear, add hydroponic fertilizer. When roots are 5-7 cm long, transfer to soil. 2. For soil propagation, plant deeply in soil without fertilizer. After propagation, avoid exposing to bright light. Gradually increase light exposure to help the plant adapt. Maintain high humidity and a temperature of 20-25°C. Alternatively, divide the plant every 2-3 years for propagation.
