The grapefruit tree is about as hardy as the orange; the lemon is much

more tender. The fruit of citrus trees will be injured by temperature at

the ordinary freezing point if continued for some little time, and the

tree itself is likely to be injured by a temperature of 25 or 27° if

continued for a few hours. The matter of duration of a low temperature

is perhaps quite as important as the degree which is actually reached by

the thermometer. The condition of the tree as to being dormant or active

also affects injury by freezing temperatures. Under certain conditions

an orange tree may survive a temperature of 15° Fahrenheit.
