Tropical Anthurium plants favor summer temperatures between 70 to 90 degrees Fahrenheit (21 to 32 degrees Celsius) and can get serious damage or death outside those temperatures. In addition to possible leaf burn, an overdose of nitrogen promotes abundant leaves but prevents flower production. Over-fertilization triggers leaf burn, which starts as browning all around the fringes and eventually destroys entire leaves.Įxcess nitrogen is a common issue.
