Temperatures For Citrus Fruits
Categories: Fruit GrowingWhat is the lowest temperature at which grapefruit and lemons will
succeed?
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.
