Planting Clementine orange

Planting clementine trees in the ground

It is recommended to plant clementine trees in fall or in spring.
You may plant it in a sun-bathed spot, sheltered from wind, so that it may have the highest possible productivity.

Growing directly in the ground is only possible in areas where winter is mild.
Farther North, you should plant it in pots so that you may bring it indoors to a cool but non-freezing place during the cooler months.

Pruning and caring for clementine trees

It isn’t really a requirement to prune.

  • Remove dead wood and clear out the center of the tree after fruit formation.
  • Clementine trees resists freezing temperatures rather well, down to 17°F (-8°C) depending on the variety, but take note that extended frost spells could be fatal.

Clementine in winter

In Mediterranean-like and warmer climates, you can grow it and keep it outdoors in winter.

When outdoors, remember it can hold to temperatures as low as 17°F (-8°C).
What is best is to use horticultural fleece which will let it cope with these low freezing temperatures best.

If you are growing it in a pot, the best thing to do is to move it to a greenhouse or an unheated lean-in so as to protect it from freezing, while letting it feel the cool it needs over its winter dormancy.
