Water only when air temperatures are above 40˚ F and apply water at mid-day so it will have time to soak in before possible freezing at night. Irrigate all plantings at least 24 hours before hard ...
Many annual plants, or plants grown in frost free areas, can suffer from damage when the air temperature drops below 40 degrees Fahrenheit (4 degrees Celsius). Tropical plants may begin to experience cold damage when the temperature is 42 to 48 °F (5 to 9 °C), symptoms include wilting of the top of the stems and/or leaves, and blackening or ...
