Ice Plant (Genus Carpobrotus)

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.

Overwatering occurs when plants receive too much water, depriving roots of oxygen and causing root rot. This environmental stress is one of the most common causes of houseplant death, as waterlogged soil prevents roots from breathing and functioning properly.

Rhizoctonia solani is a soil-borne fungus that attacks stems, roots, and young seedlings. It thrives in warm, humid weather and in soil that stays wet or drains poorly. Typical signs include seedlings collapsing at the soil line (damping-off), sunken brown lesions near the soil on stems, brown rotting roots, wilting even when the soil is moist, and slow, stunted growth. In lawns, it can cause the well-known “brown patch” during warm, humid periods. Many plants are at risk, including vegetables (such as lettuce, beans, and brassicas), ornamentals, houseplants, and turfgrass.

Bacterial soft rot is a destructive plant disease caused primarily by bacteria from the genera Pectobacterium (formerly Erwinia) and Dickeya. These bacteria produce enzymes that break down plant cell walls, causing rapid and foul-smelling tissue decomposition. It mainly affects succulent tissues such as tubers, fruits, stems, and bulbs, being especially problematic in warm and humid conditions.
