I. How To Plant

Sawtooth oaks are most often planted as 1-year transplants that are sold either as bare-rooted or containerized seedlings. Plant the seedlings where they can get plenty of light and about 25 feet apart in rows 20- to 25-feet wide. They may get enough light to survive on field edges or interspersed in pine plantings, but they will not produce acorns. One grove of 10 to 25 trees for each 100 acres of land is usually adequate. Sawtooths can be planted like pine seedlings using a dibble bar. Plant seedlings no deeper then they were planted in the nursery. Although they can grow in most soils, sawtooth oaks do best in sandy loam to clay loam soil at sites that are moderately well drained. Like most hardwoods, sawtooth oaks have thin bark and will not tolerate wildfire or prescribed burning as do thicker-barked pines.

II. Control Competing Vegetation

Sawtooth oaks do not compete well with weeds, other trees, or deer. To get maximum growth rates eliminate other vegetation within 1 foot around the seedling. After the first year, control competition around the stem to a distance as wide as the sawtooth oak's canopy. Use a herbicide that will not harm a hardwood tree but is effective on grasses and weeds. Weed mats are very effective as well.

III. Protect From Deer Browsing

Constant deer browsing where deer numbers are high can keep sawtooth oaks suppressed. In these locations it may be necessary to protect the young tree with a wire cage made from 2- X 4-inch welded wire. Build cages 1 foot in diameter and 4 feet high, and hold them upright with a 5 1/2-foot-long piece of No. 3 rebar driven into the ground. Tree shelters (plastic, transparent grow tubes) not only protect young trees from deer browsing (and antler rubbing) but also greatly accelerate tree growth. The one draw back of tree shelters is their cost.

IV. Acorn Production

Sawtooth oaks planted on reasonably productive sites using the guidelines described here will produce prolific crops of acorns in 7 to 10 years. Acorn production is fairly consistent year to year. However, minimal crops can be expected following late spring or early fall frosts. Yields from mature trees in good years range from 1,000 to 1,300 pounds of acorns per tree.

V. Seedling Sources

Many nurseries that grow pine tree seedlings are now growing sawtooth oaks. Call your county Extension agent or the Alabama Forestry Commission for names of suppliers.
