Hi. I bought this acer (possibly) a Katsura back in the spring and all the leaves were a lovely light green colour. Now in the middle of the summer it has lost its stunning colour and gone to a darker green. Is this normal behaviour or is it perhaps because its unhappy and been sun/wind scorched? I know that acers do turn to different colour but im not sure if mine is just burnt and feeling sorry for itself.
The picture shows the plant with old leaves to the left and new growth to the right. The right was the colour it was when I first bought it.
