I planted this beautiful maple spring 2020 in a spot formerly occupied by a forsythia. It get’s full morning sun but after about 1pm is shaded by a large fir. It started beautifully in spring with very white leaves and then … stasis. The leaves didn’t grow much bigger, and upon close inspection they look deformed—some of them have a bubbled texture, and since spring despite a very few new leaves it has slowly gotten slightly sadder looking. I try to keep it watered but not over watered (I hope—the ferns and hostas near it are fine). So I’m not sure what’s going on or what to do. Help appreciated!
