Growing in progress.
Grow well on rocky, sandy slopes. Considered a beautiful shade tree for parks, post oak is often used in urban forestry. Also planted for soil stabilization on dry, sloping, stony sites where few other trees will grow. Large trees are difficult to transplant and do not tolerate compaction or removal of soil in developments. The tannin in oak leaves, buds, and acorns is toxic to cattle, sheep, and goats. Poisoning occurs more frequently in drought years when other forage is in short supply. The most dangerous season is during the sprouting of new foliage, a period of about 4 weeks in March and April.
