Brown edges on leaves of plants/trees
I am new to this forum and have been looking for a topic that would discuss an issue I am having with several plants...I have a crape myrtle, a variegate wegeila and 2 viburnums that are fairly new. They were planted this year. Several of the leaves on all of these plants look scorched and brown around the edges. Some leaves have turned completely brown and scorched. I dont know if it is because of the 100+ degree weather we have been having or if there is some kind of fungus causing it. Can this be water stress or something else? I dont think I am watering too much. Any suggestions/help would be appreciates. Thanks so much!
