Clementines are a cross between Seville and mandarin oranges. The fruit is sweet, small, easy to peel and virtually seedless. You will, however, come across seeds when eating a clementine eventually. Before you decide to grow a clementine tree, consider the weather conditions where you live, as you may want to grow the tree in a pot. Clementine trees grow and bloom best outdoors in tropical regions, but the trees can also thrive in colder climates, where they can be moved indoors during the winter. Growing a clementine tree is as simple as growing other citrus trees, but it requires maintenance, care and patience until the tree flowers and bears fruit.
Clean the seeds. Using a clean towel, wipe away all fruit debris and rinse the seeds thoroughly. Pour a glass of warm water over the seeds and soak overnight. If possible, place the seeds somewhere that is warm but not hot, such as on top of a refrigerator or under a lamp. This process helps to soak off any remaining fruit.
Clean the seeds again. Remove the seeds from the glass and rinse them with clean water. Cleaning the seeds is the most important step because any leftover fruit will cause the seeds to become moldy.
Plant the seeds 1/4 inch deep in potting soil. Keep the soil moist but not wet.
Place the pot in a sunny window. If it is summer, place the container outside and provide shade from the midday sun.
Do not let your seedlings dry out. Once they have sprouted, they need time to establish their roots. A lot growth taking place at this time is below the soil, so do not transplant your seedlings right away.
Apply a good 10-10-10 fertilizer once a month at 1/2 the suggested strength on the label.
