My Red Oak Doesn’t Get Red. What Should I Do?

Question

I live in Tamaulipas, Mexico. The weather is hot most of the time, and we used to have a few cold fronts.

Answer 1

Although this tree can produce some red leaves in the fall, the term "red" primarily refers to the wood.
It may be that your tree isn't happy with the soil. The red oak needs full sun and acidic, well-drained sandy loam soil. High pH soils can cause chlorosis.
I've pasted a link to an extension article, as well as one of our own.

My best suggestion, however, is to contact a local agricultural extension office for a soil test.
