Mexican Pinguicula Heat Stress and Early Dormancy in Iowa

P. cyclosecta and P. moctezumae showed heat stress (90°F+) and possible early dry-season dormancy. P. moctezumae especially needs high insect intake or weak foliar orchid fertilizer (1/4 tsp/gal, urea-free, biweekly).

Reduce watering as leaves die back—keep barely damp. Resume normal care when new large leaves emerge (months later). Avoid constant tray watering—top-water, minimal tray water. Mexican pings aren't bog plants.
