Hi! Are Orange Dream and Shin Deshojo too sensitive? Both of my maples are showing what look like leaf tip burns - leaves that are at the end of the branches are mostly affected. I'm in Northern California and the weather lately has been around 60-68 F for the day and 45-50 F for the night. Some past days were windy as well. Maples are under the shade of the house for most of the day until around 4pm when the sun hits them. Is it the day heat that is killing the leaves or is it the cold nights? Will the leaves that have some burns recover and get bigger? Most of the leaf tip burns (or what looks like burns) are on baby leaves. The last week of February was when both the maples started leafing out. Your opinion please.
