Post Oak (Quercus Stellata)
Native of North America, the Post Oak is one of the most iconic trees of the United States. You can find them From Southern Massachusetts to Florida, west to Texas and Iowa.
Due in part to its slow growing nature, this tree offers one of the hardest woods you can find, and is very resistant to decay, which makes it fundamental for a variety of uses in construction (such as for fence posts, to which it owes its name). Among many qualities, Post Oaks are known for growing well in sandy or gravelly dry soils poor in nutrients, for its thick bark, which gives it their ability to survive fires, and because its strong horizontal branches form a round-topped crown that provides a great choice for urban landscapes and city forestry.
It is not recommended to disturb the soil underneath the canopy, Post Oaks are very sensitive to soil compaction, soil disturbance, and drainage change. This tends to happen during construction, and if we don’t take precautions, these disturbances could cause distress to the trees, damaging them beyond rehabilitation. Some preventative measures include locating the boundaries of the root system, and establishing a perimeter around it. Within this area we shouldn’t allow any traffic, digging or addition of soil, paving, or any other disturbances during construction.
Post Oaks are also sensitive to over watering. Keeping the soil excessively moist could lead to root rot, which could kill the tree. It could be a challenge to find a good balance if you have annuals, or other plants near the trees, but this could be resolved with a good drainage system.
