Pecan Tree

Pecan is a large, deciduous North American nut tree with a broad, symmetrical crown and pinnate leaves that turn yellow in autumn. It produces edible nuts and can also serve as a long-lived shade tree, but its mature size and deep taproot call for careful placement. ## Size and use The [North Carolina Extension Gardener Plant Toolbox](https://plants.ces.ncsu.edu/plants/carya-illinoinensis/) describes pecan as a tree usually reaching 70–100 feet tall with a 40–75 foot spread, with larger trees possible. It grows best in full sun to partial shade and tolerates clay, sand, or loam when drainage is good. The [Morton Arboretum profile](https://mortonarb.org/plant-and-protect/trees-and-plants/pecan/) gives a similar mature size and notes its native status, edible nut crop, fall interest, and preference for moist, deeply rich soil. ## Siting Give pecan ample room and choose its permanent location early; NC State notes that its deep taproot makes transplanting difficult. Pollination between compatible cultivars improves nut set, and NC State recommends planting multiple cultivars that include both pollination types. Nut production can vary with climate and cultivar. ## Maintenance Water during establishment and extended dry periods, especially where soil dries quickly. Monitor local pest and disease pressure if a clean nut crop is important, and allow room for falling leaves, husks, and nuts.
