Often compared to a shrub, post oaks are smaller than other oak trees. They usually grow to around 40 feet tall, up to a maximum of around 108 feet. Due to the unique needs of post oak trees, there’s a little more thought and care that goes into their maintenance, as opposed to other trees often found in the Dallas area. Here’s an essential guide to post oak care in Dallas, including care tips such as watering and trimming.

Unique Needs for Post Oak Trees

Post oak trees have a variety of unique needs that determine their care. For example, post oaks typically thrive best in high-drainage soils such as sandy-clay and sandy-loam types. While the roots of post oak trees can grow deep or shallow, they need a large amount of room to spread out, as overcrowding and disturbances can cause health issues. These trees can also attract specific pests, such as leaf beetles and insects that suck sap from the leaves or branches.

Watering Post Oak Trees

Overwatering is one of the most common mistakes that people make when caring for post oak trees. These trees are resilient in dry conditions and can experience health issues when watered too frequently. To ensure these trees receive the moisture they need to thrive, it’s recommended to water them every one to two weeks to reduce the chances of standing water pooling around the roots, one of the most common causes of root rot.

You can also test the soil of a Post Oak to see how damp it is before watering. To do this, push a wooden stick into the soil until it reaches about two inches of depth. Then, when you remove it, see at what point the stick shows moisture. If the top portion of the soil is dry, you can water your Post Oak without worrying about overwatering.

Trimming Post Oak Trees

Post oak trees also need pruning to stay healthy. However, they require much less pruning than other types of trees, usually around every two years. Precision is important when trimming post oaks to ensure they maintain their branches and don’t become bottom-heavy. Since Dallas is a hot, dry climate where post oaks typically thrive, pruning may not be necessary unless a homeowner notices significant damage to a tree, such as dead branches or invasive species infesting a specific area.

It’s best to use a professional tree trimming service for work on post oaks. Trained professionals have the knowledge and skills for the precise pruning that post oak trees require. While some people may try to prune post oaks on their own, hiring a professional tree care company almost always produces more effective results.
