Acer cappadocicum is one very hard species for hot usda zone ,clay soil very well tollerate ,no problem with hot wind o general dry problem is with caterpillar (and butterfly ) Cossus cossus when trunk is young my advice is cechk every day if there is one small hole with sap  that comes out.use one iron wire for killed the caterpillar and close the hole
