I recently received a phone call from a customer with concern about moss/algea growing on his fence and a tree. ( I believe it is moss but haven't seen it yet.) He was wondering how this has happened and if it should be a concern or should it be treated. I haven't spoken to him yet but my 1st thought it is from a result of amount of rain we had this year in the area. Maybe with the sandy soil and being about 20 mile off the ocean could have an effect. ( I dont know just thinking). If anyone has seen this before and has an idea how this has happened, effects of this to his fence/tree, and any preventatives we could take I would really appreciate it. Thanks and I hope everyone has a great holiday season.
