A: It may be a combination of issues. The guy in the middle may be suffering from over crowing, lack of sun and lack of water. Three tablespoons of Epsom salts weekly will not cure it, but may result in a toxic buildup of magnesium in the soil. You will need and onsite inspection from a certified arborist to sort this mystery out. To find one in your area go to www.tcia.org and enter your zip code. Best And Happy Yardening, Nancy
