Horse Chestnut leaves speckled

QuestionsHorse Chestnut leaves speckled
Donal Carey Staff asked 15 years ago

My question, i planted about 40 horse chestnut trees (10 years old) in October 2007, they thrived last year and had beautiful flowers early this year but since the hot spell the leaves are browning and appear to be dying. I’m now watering them but there does not seem to be any revival? will I fertilize the water? was it the sudden heat that caused this? will this set back my trees or worse? also my lime trees leaves are suffering but the ash and willow’s are grand. My site is over 6 acres so they’ve loads of room and there are plenty of other trees around/in area.
