Gardenia blooms white but then turns yellow?

I live in Las Vegas and have a potted Gardenia sitting on my patio porch. It gets partial sunlight but mostly shade. A few leaves turn yellow but what bothers me is that after the blooms come out white, they too turn yellow. Not all but many do. Any suggestions?

Gardenia blooms white but then turns yellow?
Take heart my friend. Gardenias are an extremely finicky plant. I hve had several and two I replanted (within 5 minutes mind you) keeled over and died within a week no matter wwhat I did. There are many reading your post that wish they could just keep them alive. But almost always after they bloom those beautiful fragrant white blooms they turn yellow %26amp; die. But you'll get more. Also look for aphids. I used to make a spray with 12 oz water %26amp; 4-5 harbanaro peppers crushed up let it sit for a few days shake and spray lightly.
Reply:Use cornmeal in the soil. That will stop the yellowing. I am not sure why or how it works but I know it does. Make sure its pure cornmeal. Not cornstarch. Good luck :) Report It

Reply:Gardenia is a genus of about 250 species of flowering plants in the family Rubiaceae, native to the tropical and subtropical regions of Africa, southern Asia, Australasia and Oceania.





The genus was named by Carolus Linnaeus after Dr Alexander Garden (1730-1791), Scottish-born American naturalist.





They are evergreen shrubs and small trees growing to 1-15 m tall. The leaves are opposite or in whorls of three or four, 5-50 cm long and 3-25 cm broad, dark green and glossy with a leathery texture. The flowers are solitary or in small clusters, white or pale yellow, with a tubular-based corolla with 5-12 lobes ('petals') from 5-12 cm diameter. Flowering is from about mid-spring to mid-summer and many species are strongly scented.
