Our Citrus trees are between 2-3 years old and 30″-36″ tall excluding the can size. They are ready for planting whether you choose to plant it in-ground or in a container.  For a standard citrus tree, it can reach a mature height of 20 to 30 feet tall. It may take 10 to 15 years for the standard tree to reach its full height.   For a semi-dwarf citrus tree, it can reach a mature height of 15 to 20 feet tall depending of the citrus variety.    For a dwarf citrus tree, it can reach a mature height of 6 to 8 feet.    The size of the fruit is the same on all citrus trees.
