Root Rot on string of hearts
What's Happening
Ceropegia woodii tuberous roots are highly susceptible to oxygen deprivation in waterlogged soil. Unlike desert succulents with fibrous roots, the tuber structure stores water but cannot tolerate anaerobic conditions. Prolonged moisture (>7 days) triggers bacterial/fungal invasion causing basal stem necrosis and vine collapse.
How to Fix It
- 1
Unpot plant immediately and inspect tubers—healthy tubers are firm and white/cream
- 2
Trim all mushy, black, or foul-smelling tissue with sterilized scissors
- 3
Rinse remaining healthy tissue in diluted hydrogen peroxide (1:3 with water)
- 4
Allow cut surfaces to callus 24-48 hours in dry, shaded area
- 5
Replant in fresh gritty mix or propagate healthy vine sections via butterfly method
- 6
Dispose of severely rotted tubers (>50% affected)—propagation is only salvage option
How to Prevent It
Use extremely well-draining mix: 60-70% perlite/pumice + 30-40% potting soil. Water only when soil is bone-dry 2-3 inches down and leaves show slight softening. Ensure pot has multiple drainage holes and never sits in standing water.
