Kincardineshire, United Kingdom
I have a very nice acer that has been perfectly normal until last year - when - half way through the summer, it started developing crisp and brown foliage - in parts only! The rest stayed normal. I knew it couldn't be wind burn as it is totally sheltered....in my COOL "garden room" By the end of the season - it was more or less all like you see in the picture...and it is about 5' tall and has a 2-3' spread. No insects seemed to be bugging it (!) and it was well watered. I cleared up all the fallen leaves and burned them just in case and this spring it was absolutely normal - looking stunning. Now the problem has recurred. As it is not confined to the branches that could be scorched by the sun - I am puzzled. Any sugs. anybody?
