Why have the ends of our Acer curled and turned yellow?

You are right - acers don't like sunny or windy positions. Its leaves are telling you to move it into the shade and shelter! We have an expert on this sit on growing acers - look at Sodapopkl's pictures!

Hi Simon
It's wind damage! I've just lost all the leaves on my Acer due to high winds. Needs a very sheltered position. Mine will overwinter and re-leaf next year

Its showing signs of stress and its unhappy in its new position.The problem is probably due to sun and wind exposure. Acers like shady positions away from direct sun and winds that can burn the leaves.They also like to have their roots in a moisture retentive soil but must not get waterlogged. If it is still showing signs of stress you might consider moving it back to a shady and sheltered position.Hope this helps. Best wishes, Grenville.

Hi, yes it's the wind that's caused the tips of the leaf to curl, I've had exactly the same problem with my 2 green acers this year, as since we moved up to Chesterfield the wind is a lot stronger than it was down in Leamington Spa. Don't worry thou the leaves will drop off in winter and new shoots will apear next year, just move it back in a shady sheltered spot :-)

Mine has some white spots on it

Acer Palmatum like to be growing in shady positions away from strong sunshine and winds. The brown markings on the leaves on your Acer show that it has been exposed to wind and sun damage.It is not very happy growing in its current position. Its best to move it back to a shady position in dappled light.
