I have recently purchased an acer palmatum and everything looked ok at first. However, in the last few days, some of the leaves on the top and bottom have started to dry and some have fallen. I have been watering it regularly as the land has seemed a little dry. In the morning, the acer is totally in the shade, it only starts to get direct sunlight from 1pm. Where I live it has been very hot (temperatures between 25ºC and 30ºC or more). I'm worried, what should I do?
