Our Desert Museum tree is turning brown
We planted our Desert Museum tree 4 years ago. It has been beautiful and health. In November the tree was trimmed - we were shocked when we saw how much was taken off. It is now May 2013. We just returned after being out of town for 4-weeks. The tree has gone from green to brown. I have attached 4-picture that I just took a few minutes ago.
Is our tree dying? We live in the Kensington neighborhood of San Diego which is inland off of Mission Valley, not at the beach or bay. What should we do. Any suggestions are appreciated. Thank you Jw
