I planted a new Live Oak tree last year (fall 2022).  I noticed several weeks back that the bark is splitting.  I hoped it was just from growing or temperature changes or something, but in looking at it today, I'm worried it's more than that.  I've seen tiny ant-looking insects crawling on the bark, but it doesn't seem an overwhelming amount and they are super tiny - much smaller than a regular ant - I can't make out anything but a black dot of movement.  I can't find any insects that seem like a problem.  (I did use some Diatomaceous Earth a few times just to make sure).  I live in Flower Mound.  I don't water my lawn but try to make sure to give the tree some water every week.  Can you help me figure out what I should do -- I don't want to lose my tree. 

Dear Amy, here's the response to your question:

Amy,

Thanks for your message. It appears your tree bark damage is caused by sun scald. New trees should generally have their trunks paper wrapped. See question 1 in this link https://neilsperry.com/2023/07/qa-ask-neil-july-6-2023/. 

Hope this helps.
