Drosophyllum in Southern California: Low Humidity Shock and Indoor Rescue

A Zone 9 grower’s Drosophyllum yellowed at leaf edges during a 20% humidity, 80–90°F heatwave. Plant: 10″ terracotta, peat/sand/perlite, 8 hrs full sun, watered every 2–3 days.

Jake (not a Drosophyllum specialist) suspected the extreme low humidity was the culprit. He recommended moving it indoors, raising humidity (e.g., fish tank with shop lights), and checking the CP Forum for specialist growers. Optimal temps are 75–80°F; heat + dry air may be fatal.

It's about 3" tall
