Acer - Japanese Maple

I do get a dry garden in the Summer...but one of the borders were underwater for most of the winter so I don't think mine are due to lack of water in April. 
The damage is usually to young fresh leaves during windy and cold conditions. I have a very lovely purple acer that was gifted me for a special birthday and I lost a whole main branch which didn't make it through after getting hit by a late frost and wind a few years back. I don't think they like the "openness" of my garden. I'm hoping my native hedge will grow up fast and make it warmer.
