Nuttall oak typically matures to about 75 feet in height and spreads about 60 feet, though some specimens can reach 140 feet with a spread of more than 100 feet. It is a deciduous oak known for its red to orange red late-fall foliage. Its bark is grayish-brown to black and furrowed with flat ridges. Similar to Pin Oak (Quercus palustris); but its acorns are more elongate. Acorns egg shaped and up to 3/4 inch long.
Not distinguished as a species until 1927, when it was named for Thomas Nuttall (1786-1859), British-American botanist and ornithologist. The foliage resembles Pin Oak (Quercus palustris); the ranges overlap in Arkansas, but Pin Oak has smaller rounded acorns with a shallow cup. Often confused with Buckley Oak (Quercus buckleyi) which was once illegitimately called Quercus texana.

Oaks are most often propagated from seed. No pretreatment is necessary. Plant immediately – outdoors or in deep containers to accomodate long initial taproot. Many oaks require cold temperatures to initiate shoot
development. Protect outdoor beds with Seed Collection:
Best quality acorns are picked or shaken from the tree. Collect when color has changed to brown. Best if sown immediately as acorns lose viability quickly in storage. Short-term storage in moist, shaded saw dust or sand. Acorns to be sown immediately can be soaked in hot water for 15 min. to prevent weevil infestation. Stored seed should be fumigated with methyl bromide. Seed Treatment:
Not Available Commercially Avail:
Prevent complete soil dryness, Prune to maintain shape, May be pruned 12 mo. out of the year, Fertilize 3 times a year with lawn fertilizer 3:1:2 ratio
