I have yellow leaves on my gardenia bushes, and green too. I've already used iron?

Healthy gardenia bushes get yellow leaves on them all the time. (odd ones not all the leaves). they are evergreen and when the leaves get old and need to be replaced they go yellow and drop off. Most deficiencies show up as green veins or edges and yellow on th leaf at the same time.





If the yellow is just on the odd leave, ignore nothing wrong, just nature taking its course.

Either too much water or too little. Are the leaves soft and yellow? if so, water less. If they are dry and brittle and yellow water more.
Reply:There are so many reasons a gardenia will have yellow leaves. We always hear too much or too little water. Try putting it in a less sunny location for awhile. If it's in a pot, water once a week and use a 20-20-20 fertilizer, one tablespoon per gallon of water. After about one month, plant in a partial sun in the ground. Make sure you water fully the first time, then follow up with a good plant food every couple of weeks. Allow soil to dry between waterings.
Reply:Sounds like a mineral deficiency. Try adding some calcium (a little cornmeal) and some epsom salts (Magnesium Sulfate).


Gardenias need a bit of both.
