About

Quercus falcata, also called southern red oak, spanish oak, bottomland red oak or three-lobed red oak is an oak (part of the genus Quercus). Native to the Southern United States, it gets its name the "Spanish oak" as these are the areas of early Spanish colonies, while "southern red oak" comes from both its range and leaf color during late summer and fall. The southern red oak is a deciduous angiosperm, so has leaves that die after each growing period and come back in the next period of growth.

How to grow it

The southern red oak is cultivated in eastern United States in USDA Zone 5a to USDA Zone 9b.

It can survive lows from −23 to −28.8 °C (−9.4 to −19.8 °F) and highs of 38 °C (100 °F).

Where it grows

Quercus falcata occurs in sandy, loamy or clay soils of upland sites. These soils are often dry, acidic and nutrient poor. In suitable habitats, the species can be found from southern New York (Long Island) south to central Florida and west to Missouri, Oklahoma, and Texas. In the northeastern portion of its range the species is relatively rare and found almost exclusively along the coast; its highest prevalence is throughout the piedmont region of the Southeast.

Uses

The southern red oak is a tree with diverse potential uses, such as for manufacturing of floors, furniture, construction materials and lumber thanks to the sturdy, durable and coarse-grained wood it provides. The southern red oak is vital in the southeastern United States due to its abundance, providing around 8.1% of annual hardwood volume. Southern red oak wood is used as a fuel source because of its high heat value. The southern red oak provides tannin, which is used to preserve and treat leather. The southern red oak has a large root system that provides watershed protection to reduce flood damage and soil stability. Other uses for southern red oak include as shade trees and aesthetic uses in gardens. Southern red oak can provide acorn mast for deer, squirrels, turkeys, song birds and quail.
