I'm new to this forum. I posted a similar question about this yesterday but received no replies. May be I don't know how to look for a reply. I have some gardenia plants that were doing very well. suddenly some of them are getting yellow an ready to die. They were planted before moved to this house, so I don't know how well they were taken care of before. I looked at some internet site that recommended acidic fertilizer but I couln't find it at the home depot. Can someone help.
thanks and sorry for the long post.
