How to Grow Clementine Orange Trees

Overview

Clementine oranges, a small variety of mandarin oranges, are sometimes referred to as Algerian tangerines. Their small size, ease of peeling and lack of seeds make Clementine oranges perfect for eating raw. Growing well in tropical and subtropical regions, trees planted on the south or southeastern side of landscapes flourish when protected from the cold.

Step 1

Remove grass and weeds from the planting area. Keep grass and mulch at least a foot away from the tree trunk.

Step 2

Dig a hole twice as wide as the root ball. Gently rinse the growing medium from the outside of the root ball, exposing the outermost roots.

Step 3

Place the Clementine orange tree in the hole slightly higher than it was in the nursery container so the bud union is above the soil level. Backfill with native soil until the hole is filled halfway. Water the tree to settle the soil. Finish filling the hole and water again. Make sure the root ball is completely covered with soil.

Step 4

Use additional soil from the landscape to build a watering ring. Form a ring of soil about 5 to 6 inches high and 6 to 8 inches wide around the outside of the planting hole. Water the tree by filling the watering ring with water and allowing it to soak in.

Step 5

Water the newly planted Clementine orange tree every two to three days for the first two weeks. Gradually increase the time between watering. Water young established trees every seven to 10 days and mature trees every two weeks during dry weather.

Step 6

Fertilize once the tree is established and new growth appears. Use 1/4 cup of ammonium sulfate every three months during the first year. Use 1/2 cup during the second year and 3/4 cup the third year. In subsequent years, use 1 cup of fertilizer per year of tree age, divided into three or four feedings per year.

Step 7

Protect Clementine oranges from the cold during severe freezes by banking soil around the tree trunk and covering it with blankets or tarps whenever a hard freeze is expected.

Step 8

Prune Clementine orange trees only to remove damaged or dead limbs.
