I recently re-potted my Acer into a larger pot using multi-purpose compost but the leaves are now drying with what looks like bleach marks and brittle and just keep falling. It’s not been too windy and we have had some sun (it’s mid May) but it usually copes really well anyway with temperatures and some wind. Can I save it, is there anything I can do? I can’t attach photos - they’re too large.

  • please post some photos. You can resize them to be smaller from a setting on your cell phone or with paint if you use windows – kevinsky May 20 at 12:23

Photographs would have been helpful for a clear answer. The usual cause of whitish or tan marks and shrivelling is exposure to wind; second is very hot sun. If you're in the UK, we did have some pretty windy weather a few days ago which has caused some problems with Japanese acers of the type you mention, along with leaves shrivelling due to a sudden drop in temperature after a very warm February/early March. Frost damage usually causes blackened leaves though. If its any of these that caused the problem, it should put out new leaves...

The other possibility is perhaps the rootball is too dry - because we don't know how large the rootball of the plant was, nor how large the pot you've repotted into is, is it possible you've repotted into too large a pot? It should be no more than 1 or 2 sizes larger than the original pot you transferred it from; larger than that, and its possible for the compost to be wet, but the rootball to be dry... Otherwise, did you water it in well when you repotted, sufficient to thoroughly wet all the new potting soil...allowing excess to drain out freely from the bottom of the pot?

  • Hi. Thank you for your answer. I am uk based but it’s never done this before. I guess it could be the temperature changes we’ve had. The leaves haven’t blackened, just got bleach-like patches on them. I potted it into a pot maybe 2 sizes bigger. Made sure it’s watered sufficiently with excess draining out of the extra drainage holes I put in it. Really hoping it will come back. It’s a bloodgood variety and it’s stunning usually. – N.

  • I'm betting on wind damage - those leaves would have been pretty new and more vulnerable because of that... – Bamboo May 19 at 20:29
