What you describe sounds like maple leaf scorch and it is common with young maple trees. Leaf scorch is caused by failure of the tree to supply enough water to the leaves at a critical time, usually in July and August. A great amount of water
evaporates from the leaf surface because of sun and wind during hot, dry weather. If the water supply is deficient, the exposed leaves dry out and scorch. Trees
with small root systems are particularly subject to leaf scorch. Newly planted trees are especially prone to leaf scorch during the first two to three years following
planting. Leaf scorch symptoms may also appear following damage or disease in the roots or injury to the trunk. To help your tree avoid this problem next year, try watering deeply during the hottest months of the year. Apply water slowly so it has a chance to trickle down and wet the entire root systems. Best wishes with your maple!
