Overwatering on aloe vera
What's Happening
Aloe vera is extremely susceptible to overwatering damage due to CAM photosynthesis and succulent water storage adaptations. Unlike tropical plants, Aloe's thick leaves store water for 4-6 weeks, making frequent watering unnecessary and harmful. Overwatering creates anaerobic soil conditions that enable Pythium fungal pathogens, causing roots to turn black/mushy within 7-10 days. Leaves become soft, translucent, and yellow at the base—distinct from underwatering which causes wrinkling.
How to Fix It
- 1
Stop all watering immediately upon detecting soft/mushy leaves
- 2
Unpot plant and inspect roots: healthy roots are firm white; rotted roots are black/mushy/foul-smelling
- 3
Trim all rotted roots and leaf bases with sterilized scissors
- 4
For advanced rot: Behead plant above rotted stem section; remove lower leaves to expose 1-2 inches of stem
- 5
Allow cut surfaces to callous 24-72 hours in dry shaded area
- 6
Repot in dry well-draining succulent mix; withhold water 7-14 days; then water lightly every 2-3 weeks
What You'll Need
How to Prevent It
Water only when top 2-3 inches of soil are bone-dry (typically every 2-3 weeks indoors, longer in winter). Use well-draining succulent mix with 50%+ perlite/pumice. Always use pots with drainage holes. Terracotta pots wick excess moisture naturally. Never water on fixed calendar schedule.
