What is a Post Oak? (with photo)

Post oak is very drought resistant.

Oak post is a deciduous tree that is part of the Fagaceae, or beech, family. It is native to the eastern half of the United States. This tree has an oval shape and a light gray or reddish-brown trunk. It is commonly used as a shade tree or as an ornamental tree. Gypsy moth and oak wilt, a fungal disease, are two concerns to watch out for when growing post-oak.

Scientifically, post-oak is known as Quercus stellata. The genus name Quercus is derived from the Celtic words quer and cuez, meaning “good” and “tree”, respectively. The species name, stellata, means “little star”. Commonly, post oak is also called iron oak or cross oak. In other regions, this tree is known as post-delta oak.

The post-oak is distributed from Massachusetts to central Florida. It is also grown from western to eastern Kansas and central Texas. This tree populates the dry, sandy ridges of the landscape, as well as prairies and limestone hills. It is also found in woodlands and deciduous forests.

This tree usually grows to 40 to 50 feet (12 to 15 m) tall and spreads across a similar width. The foliage consists of green leaves 3 to 5 inches long (7.62 to 12.7 cm). They have a wavy outline and feature multiple lobes. As the tree matures, it develops a thick oval crown. The leaves change color during autumn.

In early spring, the tree blooms pale yellow or green flowers. After that, the tree produces acorns that range from light brown to black. They grow to about 0.75 inches (1.9 cm) in length.

Experts recommend that this tree be grown in rocky or sandy soil that is acidic. Growing conditions improve dramatically if the soil is well-drained. The area where the tree is placed should have full exposure to sunlight. This tree is very drought resistant and is a good choice for tropical landscapes.

Xeric landscapes, or xeriscapes, are landscapes that contain plants that only require natural rainfall to survive and do not require additional irrigation. This type of landscaping is ideal for drought-prone regions. Post oak fits well in this type of landscape; her acorns attract many wild animals and she hosts several butterflies.

One problem that affects this tree is oak wilt. This is a fungal disease that causes the leaves to turn yellow or brown. Affected trees should be pruned to reduce the chance of the fungus spreading.
