Q.Two of My Plants Are Sick
I have a 10 foot ixoria bush and the leaves are either falling off or have red spots on them. I have tried fertilizer and insect spray. It only got worse. I also have a gardenia tree that did not bloom this year and the bark has big white spots on it and the leaves are yellow. I do not over water and have tried epsom salt and fertilizer and have added fresh dirt. The trees are 6 feet tall and have always bloomed and been beautiful. Please advise

The ixoria may have fire blight. Plants with fire blight will have leaves with a red coloring and spots. This article discusses Fire Blight: https://www.gardeningknowhow.com/plant-problems/disease/fire-blight-remedies-and-symptoms.htm
