Almost always too warm at night or too dry. This species needs cold nights and 80%+ humidity to form pitchers.
Sudden decline in heat
Warm spells stress this cool-growing highlander badly. Keep day temperatures moderate and nights cool; provide airflow.
Browning, crisping leaves
Hard water or low humidity. Use only pure water and keep humidity very high and steady.
Root rot from wet, dense media
