Although the pecan hickories (which include nutmeg hickory) grow more rapidly than the true hickories, specific information on the growth rate of nutmeg hickory is lacking. The pecan hickories, in turn, grow more slowly than most other bottom-land hardwoods. The average 10-year diameter increase for hickories in natural, unmanaged stands in the northeast Louisiana delta was 4.3 cm (1.7 in) in the 15- to 30-cm (6- to 12-in) diameter class; 3.3 cm (1.3 in) in the 33- to 48-cm (13- to 19-in) diameter class; and 3.8 cm (1.5 in) in the 51- to 71-cm (20- to 28-in) diameter class.
