Red Japanese Maple 25 years old

Hi can anyone help
My red Established Japanese Maple has started getting marks on leaves and the top canopy the leaves are crispy and dry.
What shall I do?

I suspect it could be the recent cold snap coupled with cold drying winds, at the moment the foliage is quite tender as it has only just emerged. I would just watch it carefully and see if the problem spreads over the next few weeks.

 

I have noticed over the past couple of years, how gardeners are becoming more and more aware of problems in the garden and the outside world. This is very commendable. However may I stress. It is so very easy for the average gardener to become perplexed and anxious.


Most appreciativly many forum members go to great lengths to help and advise others. Sometime we as individuals may be able to afford help to a plant/subject. Sadly at other times, even the most quailfied and experienced fail to be of help. Never lose hope. Keep trying and giving support to each other.
