Acer in trouble - please help
Hi my usually beautiful Acer which is usually bright green this time of year is instead orange/pink as it often is in Autumn. Several branches look like they’ve died with dried up leaves. The leaves which are alive/pink in colour have strange dark patches on them. Any ideas? It got a bit dry 2 months ago but I can’t believe it’s that as it was not that hot then and it’s got that dry in the past and this hasn’t ever happened before.. I would really appreciate some guidance.
