How to Transplant Algerian Mandarin

The "Algerian" Mandarin (Citrus reticulata or Citrus clementina) is one of the sweetest citrus varieties, growing into a small evergreen tree with glossy, dark green foliage. Originating in North Africa, the tree grows throughout the mildest regions of the country in U.S. Department of Agriculture plant hardiness zones 8b to 11. Whether moving an existing mandarin to a new location or transplanting from a container, proper care and technique must be followed to avoid unnecessary stress to the plant.
  1. Timing

    • Under most circumstances, an Algerian mandarin should be transplanted in spring after all danger of frost has passed, assuring good root growth and establishment before the following winter. This is especially important for planting young trees that have not yet developed the cold hardiness found in mature trees. Established trees fare well when transplanted in early fall because the cool weather of winter reduces the loss of moisture from plant tissues. In frost- free regions, late winter is an ideal time to transplant a mandarin as there is no danger of freeze damage. Transplanting in summer rarely succeeds.

    Excavating a Tree

    • When transplanting an established Mandarin, preserve as much of the root system as possible to ensure success. Start by digging a trench 8 to 10 inches deep in a circle 12 to 24 inches from the trunk, depending on the size of the tree. With a pointed shovel, slice into the soil at the bottom of the trench at a 45-degree angle towards the trunk. Gently pry up on the root mass all around the tree until the remaining roots are free. With a helper, lift the tree onto a tarp or wheelbarrow and transport to the new location.

    Planting in a New Location

    • The Algerian mandarin needs a warm, sunny location and well-drained soil. Dig a hole to the depth of the root ball and about twice as wide. Plant the tree so the soil level of the root ball is consistent with the surrounding grade, and mix a few shovels of compost in with the soil as it is returned to the hole. Tamp firmly to make sure no air pockets remain around the roots, and water thoroughly. Follow the same procedures for transplanting a mandarin from a pot, but loosen the outer roots so they are no longer confined to the shape of the container.

    Transplanting Tips

    • Full-grown trees cannot be transplanted without heavy machinery and should not be attempted without professional assistance. Moving a tree shorter than 6 feet is a realistic goal, however, but some heavy labor is still involved. To make it easier, water the area around the tree, as well as the new planting location, the day before. On larger trees, cut back the canopy up to 30 percent to reduce moisture loss and to provide better access for digging around the trunk. Plant in the new location immediately -- the roots will desiccate quickly when they are exposed to air. Water the transplanted citrus tree twice per week during the first growing season after transplanting. Maintain a weed-free area around the root zone to aid in successful establishment.
