Pre-treatment: Seeds are planted in late October using a Love seeder set at 2nd gear at 9 setting into prepared field beds.

Establishment: Seeds are purchased from local people who collect within a 50 mile radius of the nursery. The fruit is a large yellow-green fruit containing many seeds. Osage orange is native to the bottomlands of southern Arkansas, eastern Oklahoma and eastern Texas. It is widely planted as living fences and for its ornamental traits, and is widely naturalized in areas outside its natural range.
