:cry: The leaves on my trees look shriveled then turn yellow and brown and start dying. I have lost four trees so far. Need help fast as another one is dying . They are around 10 years old

I am sorry to be the bearer of bad news, but if you go to Howard's books and look up Bradford Pear, which I suspect your trees are, you will see that this is a tree that has problems in the North Texas area. They are short lived and are suseptible to soil born diseases.

I would suggest you replace them. I think Howard would give the same advice. I know it is hard to get rid of a tree that you have enjoyed for some time, but a better adapted tree is worth the trouble.
