Edema
Edema (also spelled oedema) is a non-infectious physiological disorder caused by an imbalance between water uptake and transpiration. When roots absorb water faster than leaves can release it through transpiration, cells in the leaf tissue swell and burst, forming characteristic wart-like blisters. This is purely a cosmetic issue and does not threaten plant health.

Root Rot
Root rot is a serious fungal disease that affects the root system of plants, causing them to decay and die. It is primarily caused by overwatering, poor drainage, or soil-borne fungi such as Pythium, Phytophthora, Rhizoctonia, and Fusarium. The disease thrives in waterlogged conditions where roots are deprived of oxygen, making them susceptible to fungal infection.
