Louise Lynch Staff asked 15 years ago

Of 5 ten year old whitebeam( i think) trees , the leaves on two have shrivelled and they have stopped growing. The other three look like they are heading the same way. Pic of spotty leaves is attached. Twigs do not seem completely dead as yet.The garden is fairly heavy clay.All 5 trees flourished up til now. Is ther anything i can do?
