Can I Use Epsom Salt on a Gardenia With Yellow Leaves?

Question

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?

Answer 1

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:
