Amy is quite correct. The leaf burn is usually attributed to wind or poor soil or both. I water my trees in the hottest part of the day sometimes and never expierance leaf burn due to the hot sun. I took a large elm grove to Hanford last week to prune it at the club meeting. Hanford is about 55 miles from my house. I went by way of the freeway. The elms had some shoots about 6" long sticking out from everywhere. When I reached the club, the shoots had no leaves on them. The 60 mile per hour 95 degree wind storm that I had subjected these poor trees to had dried out all the leaves and blew them right off the stems. When I got the tree into the building all I had to do was cut off the bare stems. It had dried out the leaves right to the sillouete of the tree.

You must develop a watering habit of your own. Water the trees at the same time of day. If you don't want to water when its hot then water in the morning. Under watering will cause leaf burn in maples, and overwatering will cause the leaves to turn yellow. Hope this helps, Bonsaial
