Orange trees can be grown from seeds, but they might not conceive or produce fruit that is different from the parent tree. For the seed of a business orange to develop, it should be kept damp consistently. Although many cultivators simply plant the seeds directly into the soil, one method is to place them between two sheets of damp paper towels until they germination.

Economically developed orange trees are engendered abiogenetically by joining an experienced cultivar onto a reasonable seedling rootstock to guarantee similar yield, indistinguishable natural product qualities, and protection from infections over time. There are two stages to propagation: First, seeds are grown into a rootstock.

The leafy top is then removed after about a year and a bud from a specific scion variety is grafted into the bark. The orange variety is determined by the scion, and the tree’s resistance to pests and diseases and adaptability to particular soil and climate conditions are made possible by the rootstock. As a result, rootstocks affect fruit yield and quality in addition to the growth rate.
