关于这种疾病
A physiological condition in which stems elongate abnormally due to insufficient light or excess water and nutrients, commonly seen in succulents and cacti.
主要症状
- Stems elongate abnormally with wide gaps between nodes
- Leaves turn pale yellowish-green
- Spacing between leaves widens, distorting the natural shape
- The plant develops a spindly, stretched appearance compared to normal growth
主要原因
- Severely insufficient light in the growing environment
- Overwatering or excessively frequent watering
- Excess high-nitrogen fertilizer application
- Long-term placement in a poorly ventilated, hot, and humid environment
预防（栽培环境与日常管理）
Provide adequate sunlight (several hours of direct or bright indirect light daily). Water only after the soil has completely dried out, and limit fertilization outside the active growing season.
