Throughout southwest, we enjoy the shade and fall color of many varieties of Ash Trees. However, one thing all varieties have in common is that they are all susceptible to Ash Decline. This condition is just that - a general decline of an Ash tree over several years, until it ultimately dies. It can be caused by poor planting location or soil conditions, pests, or weather stresses.  

Symptoms of ash decline include yellowing leaves (other than fall color), loss of leaves, dead branches, and cracks in the trunk near the ground. When an Ash Tree is experiencing Ash Decline, it may seem to be recovering in the spring as new growth begins to appear. But by the peak of summer, usually July/August, it will begin to show signs of decline again. Once an Ash is in decline, unfortunately there is no cure or remedy to save the tree. However, Ash trees are resilient and proper management of your trees can improve their life expectancy. Some recommended practices include following proper trimming/pruning techniques and schedules, removing dead limbs, and removing other trees already affected by Ash decline.
