Mandarin oranges originated in China and Southeast Asia and arrived in the United States in 1878. They are small oranges with easy-to-peel skin that is light orange -- lighter than tangerines. Mandarin oranges are hardy between USDA zones 8b to 11 and need protection from temperatures below 25 degrees Fahrenheit in most cases. If you live in the right climate, planting a mandarin orange tree is easy.
Select a place for your mandarin orange tree. They need full to partial sun and well-drained soil. Mandarin oranges tolerate many soil types, from sandy to clay.
Dig a hole for the mandarin orange tree as deep as the root ball and twice as wide.
Place the mandarin orange tree into the hole and fill the hole halfway with soil. Fill the hole with water and wait for the water to drain. Finish filling the hole with soil and pat it down firmly.
Water the mandarin orange tree immediately for 5 to 10 minutes.
