Why are the leaves of my gardenia bush turning yellow?

Yellowing leaves usually means too much water. Check the soil around your plant, not just the top of it, but go in, under the first few inches and check how moist the soil is. Also, you might want to check with your local gardening center for specific plant food for gardenias, different plants take different feed compositions (nutrients) and apply as necessary.

Why are the leaves of my gardenia bush turning yellow?
the first answer was spot on, I was told to use epsom salts on mine, and it really did make a difference. I think the salts replace a nutrient or salt that they need and easily are depleted of.


If this doesn't work, however, I would consider moving the plant, as they don't like a lot of sun, and their leaves will also turn yellow if this is the case. They prefer just the morning sun, not the afternoon, or dappled shade.
