Meticulous care was given to the development and planting of the Welty mandarin orchard. All of the original, seedless satsuma mandarins were budded from the cuttings aged mother tree in Thermalito, CA. The trifoliate rootstock was chosen for its cold hardiness, in spite of the fact that this particular rootstock/budwood combination is known to grow on a much slower cycle than the average rootstock—a cycle of up to 15 years.
