A customer has 2 different types of Acers, one being Acer Palmatum Dissectum (Garnet) and i'm not sure of the name of the other species. But it is a more upright type with larger leaves. (Like the 2nd one in from the left, whereas the "Garnet" is the one on the far right.
They are located close to a water feature which I noted can let off a fine mist when it is windy.
Bothtypes of tres are showing signs of damage. The 'Garnet' had some leaves which were completely brown and had a "rotten" damp look to them whilst the larger Acer has some leaves which have gone brown in places. No leaf is completely brown they are literlly patchy.
There are 3 'Garnets' and they are all suffering in the same way.
The trees were only planted approx 1 year ago.
Do you think they are being effected in some way by the spray coming from the waterfall or is there a known disease that can effect Acers??
I cannot see any living insects on the tree anywhere.
The pond uses only tap water which is then passed through a filtration system, no chemicals are used as the pond section has several healthy fish in it.
Your help would be appreciated......

Picture of the setting?
Acers turn brown if they get too much wind, sun, hot, cold, loads of reasons.
If they are in full sun around a water feature, and the leaves are getting splashed, they might well burn. Delicate Acers should be in sheltered, semi-shaded positions.
Whats the soil like? If they were only planted last year they can take a while to put enough roots out to be happy. I had some planted in a not ideal soil and they took more than a year to acclimatise, until then, their leaves often browned and crisped. Trees can often exhibit some 'transplant shock'. In spite of the last month have they had enough water!?
sounds like leaf burn from the sun hitting the droplets of water to me but yes, a pic of the offending tree would be great
Thanks for your replys.
I will try and post a pic when im at the property next week. I think the soil is OK as it is a mix of top soil and compost, and he does tend to water fairly well.
Certainly leaf burn does seem likely. I will update this Discussionas soon as I have a pic.

I thought the water droplet, leaf burn effect was debunked a while back.
Not specifically Acers but here you go:

Verticillium wilt? Acers are very susceptible to this. I hope not - but maybe worth a stem check.
What are the tell tale signs. "floppy branches??"
I did check branches and looked for any signs of insects etc but all looked fine.
