What makes my redbud tree die out on one side?

A redbud tree dying out on one side can be caused by several factors, including environmental stress, disease, or pest infestations. Uneven watering or poor drainage may lead to root problems, while fungal infections like Verticillium wilt can affect one side of the tree. Additionally, physical damage from weather, animals, or improper pruning can contribute to uneven dieback. It's important to assess the tree’s overall health and consider consulting an arborist for a proper diagnosis.
