We have some property in Galveston County, in an area that is notorious for poor soil. Have an oak tree "trying" to grow, which is encouraging since others planted at the same time simply died. Unfortunately this survivor has a condition seen with other young oaks in this area, poor leafing on the newer spindly limbs. Please see attached photo. Anybody have any ideas what is the cause? Lack of water, pH issue, needs particular nutrient, etc... Many thanks for your expert help!
