I have had an acer palmatum for about two years. Last year the plant dried up a bit but the problem was solved. In the winter I moved the plant to a larger pot with a drainage hole. In the last few days, some of the leaves on top and bottom started to dry out (are Brown and curled) and some fell off, being much worse than what happened last year. I have been watering regularly, as the soil seems a bit dry. In the morning, the acer is totally in the shade and catches wind, it doesn't start getting direct sunlight until 1pm. Where I live, in a coastal area very close to the sea, it has been moderately warm (temperatures between 22°C and 26°C). I am worried, what should I do?
