The Stuart Pecan tree is the best all-around pecan tree. It yields 40-50 nuts per pound, and the nuts are large and easy to crack open because of their thin and fragile shell. Inside, the kernel is plump and firm-textured with a rich flavor. The tree grows to a mature height of 75 to 100 feet. The Stuart is a Type-2 pollinator and should be pollinated with Type-One pecan trees. It is hardy in Zones 6-10 and can be planted in full sun or partial shade. The soil should be deep, moist, and well-drained. USDA ZONES: Zone 6, Zone 7, Zone 8, Zone 9, Zone 10.
