I heard on TV that if you have problems with yellow leaves on gardenias, to use a solution of water and Epsom salts on it. Is this true? If so, how much do you use?

Epsom salt is magnesium sulphate. For the gardenia, it will help prevent yellowing of the leaves. Use 1 tbsp. of Epsom salts per foot of height of gardenia. This article may also help:
