|I have 2 Japenesse maple trees. One is a year old the other planted this spring. The leaves are starting to turn white around the edges. The oldest is mainly on the bottom. What is causing this and what can I do?

|Sounds like leaf scorch and/or delayed transplant shock, both of which can cause color change on the leaf margins. Leaf scorch is a noninfectious condition caused by an unfavorable environment. Japanese maples appreciate some filtered shade from hot afternoon sunshine and like well draining but reasonably moist soils. I think as your trees settle into their new homes they will stop showing signs of stress. Just water them as necessary all summer long so they can establish their root systems. Best wishes with your trees.
