Grafted Tangerine Seedlings

Grafted Tangerine Seedlings (Exportable)

Tangerines grow well in areas that don’t have harsh winters and will produce an abundance of flavorful fruit every year with just a little bit of help. The fruit often ripens in the winter or early spring, making tangerines a popular winter snack and a traditional Christmas favorite in many homes. While a single tree can produce fruit on its own, planting more than one tangerine cultivar in an area can increase the yield of tangerines on all the trees.

Tangerines are relatively cold-tolerant, making them easier to grow than oranges, grapefruits, and other types of citrus. Some varieties, such as the Citrus reticulata “Dancy,” are heat-tolerant and do best when summers are hot, but other types, including the Citrus reticulata “Sunburst,” do best when summers are on the cool side.

Citrus species can thrive in a wide range of soil and climatic conditions. Citrus is grown from sea level up to an altitude of 2100 m but for optimal growth a temperature range from 2° to 30° C is ideal.

Long periods below 0°C are injurious to the trees and at -13° C growth diminishes. However, individual species and varieties decrease in susceptibility to low temperatures in the following sequence: grapefruit, sweet orange, mandarin, lemon/lime, and trifoliate orange as the hardiest.

Temperature plays an important role in the production of high-quality fruit. Typical coloring of fruit takes place if night temperatures are about 14° C coupled with low humidity during ripening time.

Exposure to strong winds and temperatures above 38° C may cause fruit drop, scarring, and scorching of fruits. In the tropics, the highlands provide the best night weather for orange color and flavor.
