Venus Flytrap Heat Damage from Car Exposure: Recovery Steps

A grower in Johannesburg, South Africa left three newly purchased Venus flytraps in a sealed plastic container in a hot car for two hours. Upon return, all traps were closed, brown, and appeared severely damaged. The plants were potted in sphagnum peat and placed in saucers with distilled water.

Assessment: Severe Heat Damage

Temperatures inside a closed car in direct sun can exceed 100°F (38°C), causing not just sunburn but thermal cooking of plant tissues. The brown, closed traps and dry trap teeth indicate extensive damage.

Recovery Protocol

1. Cut off all leaves (traps are modified leaves) at the base.
2. Keep pots sitting in water in a sunny location. New growth requires full sun to develop properly.
3. Wait 2 weeks. If the rhizomes survived, new growth should emerge.
4. If no growth appears after 2 weeks, the plants have perished.

High heat caused the damage, not sunlight itself. The new growth will need full sun exposure. This is a last-resort attempt; survival is uncertain.
