When growing citrus trees in cold climates, the degree to which damage may occur is related not only to the temperature but a number of other factors. Citrus trees that are cold tolerant down into the low 20s, such as tangerines and mandarins, are the most optimistic choice for planting cold climate citrus trees. Sweet oranges and grapefruit are slightly more tolerant and can withstand temperatures in the mid 20’s before succumbing. Cold Climate Citrus TreesĬitrons, lemons, and limes are the least cold hardy of the citrus trees and are killed or damaged when temps are in the high 20s. Fear not, there are some cold hardy citrus tree varieties and, if all else fails, many citrus trees can be container-grown, making them easier to protect or move if the big freeze hits. Citrus are semi-tropical to tropical fruit crops which are fairly low maintenance and easy to grow, but not usually in regions where temperatures dip below 25 degrees F. When I think of citrus trees, I also think of warm temps and sunny days, perhaps combined with a palm tree or two.
