The Caddo is a highly productive pecan tree, yielding about 60 nuts per pound. The pecans ripen in mid season and have excellent shelling characteristics so you can get right to enjoying them! They are oblong elliptical to oblong shaped nuts. The tree grows to a mature height of 75 to 100 feet. The tree is moderately scab resistant and is a Type-1 pollinator, or a protandrous, meaning that its pollen sheds prior to stigma receptivity. Because of this, the Caddo should be pollinated with Type-Two pecan trees. The Caddo thrives in Zones 6-10. USDA ZONES: Zone 6, Zone 7, Zone 8, Zone 9, Zone 10.
