Orange Tree Planting Methods and Care: A Detailed Guide to Sowing Methods and Growing Conditions
It takes about four to fifteen years from seed to flowering and fruiting for an orange tree to produce its first flowers and fruit. So how do you plant orange seeds? Would you like to know? Let's take a look at how to plant orange seeds.

Pick the seeds out before the orange shrivels. After the seeds are removed from the fruit for a while, they generally become shriveled, and such seeds have a very low germination rate. Watch out for seedless varieties. Ask the seller clearly when buying.
Wash the seeds. After washing, they do not need to be air-dried. Keeping a certain degree of moisture can improve the germination rate of the seeds. Keeping the seeds moist will make them sprout faster.
Plant the seeds in a pot with well-draining potting soil or in the ground. When planting, place the seeds about 1.2 cm below the soil surface. [6] Orange trees are not picky about potting soil, but be careful that the seeds (and later the roots) are not soaked in water, or they will rot. [7] When you water the soil, the water should be able to drain quickly from the bottom of the pot. You can also buy compost for potted oranges and mix it into the potting soil; this will help the orange tree retain nutrients and make the soil more acidic (low pH), promoting vigorous growth of the orange tree. [8]
Give the soil plenty of sunlight. Whether indoors or outdoors, soil between 24 ºC—29 ºC is ideal.
Fertilize the soil every two weeks (optional) with a balanced fertilizer. If you want to increase the tree's growth rate, apply a small amount of fertilizer to the soil every 10—14 days. Once the seedling grows into a small tree, stop fertilizing. See how to grow seedlings or small trees and follow the instructions. The small tree can only be fertilized in its second year of growth.
After the seeds sprout, pull out the weakest of the three seedlings. Citrus seeds have the special ability to clone the mother plant exactly, also known as nucellar seedlings.
