Root Rot
🔎 按症状查找
关于这种疾病
A serious condition in which roots decay due to overwatering or poor drainage, causing significant deterioration of the entire plant — one of the most common problems in succulent and cactus cultivation.
主要症状
- Lower leaves and the base of the stem become soft and mushy
- The stem base and lower stem turn brown to black
- Leaves drop off easily in succession
- The plant remains wilted after watering without recovering
主要原因
- Frequent or excessive watering keeping the soil constantly moist
- Use of poorly draining soil mix or pots without adequate drainage
- Persistently wet conditions during cool or cold periods
- Root-bound plants with lost aeration in the root zone
预防（栽培环境与日常管理）
Use well-draining succulent/cactus mix and pots with drainage holes. Water only when soil is completely dry, and significantly reduce watering during the dormant season (winter).
