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.

I just bought a gardenia plant. The instuctions are in deutsch, so I´ve no idea how to make it grow and bloom

I know I should grow it in a container, but how much water do I give it, and what kind of sun/no sunlight?





Thank you!

They like high humidity and high light intensity, but keep it relatively cool (especially at night, it likes to be around 60 degrees). Mist them often with a spray bottle, and keep the soil acid (look for azalea or acid-loving plant food).





Don't be upset if it dies or starts dropping leaves...those things aren't easy to keep alive indoors, especially when they're young. If you keep them too wet, they'll get gnats (let it dry out a little to kill off the babies), and if they're too dry, watch out for spider mites--little webbing between where the leaves meet the stem. If this happens, give your plants a shower (literally, stick them in the shower for a few minutes)


As with most house plants, stick your finger in the soil about an inch. If it feels dry, water it thoroughly (make sure you dump out any water that drains out the bottom, though). If it still feels moist, give it another day or two.





Hope this helps, good luck!
Reply:Ask at the place where you bought it! or look it up on the web. I think gardenias are from a warm climate, so unless you live in the south, yours may not last the winter. But you can enjoy it now!
Reply:Call the shop you bought it from. They should be happy to help you!

More blooms on a Gardenia?

I was just wondering if someone could tell me what makes a gardenia bloom more often. Mine seems to just have one at a time as a rule, the minute one is brown and falls off, another one blooms. My boyfriend's mother has one just a little bit larger than mine and it is full of them. Does this depend on climate? Sun? or just depending on the plant?

I have found that my gardenias do not bloom if they are in full sun. Once I moved them to partial shade, they started blooming like crazy!

What can I do to help with yellow foliage on Gardenia bush? (In coastal North Carolina)?

They do that at this time of year. It's a gardenia thing.





Epsom salts sprinkled around the drip line, water in with miraclegro, poke rusty nails in the dirt.





good luck, neighbor (mb, sc)

Help with diseased Gardenia Bushes ?

I have two very big Gardenia bushes in my yard and they both have this black stuff all on the leaves. I'm not sure if its a disease or something else they bloom every may 27th like clock work but that black stuff has been on the leaves for years now and I cant get rid of it. What should I do cut both plants down to the ground and let them grow back and if I should do that then when would be the right time of the year to trim them down? thanks to everybody who will answer this.

We've had the same problem. The black on the leaves is a "sooty mold" usually caused by whiteflies. Every so often, plants need a "bath" of sorts. Use Johnson's Baby Shampoo mixed into a gallon or so of water and put it in a pump-up garden sprayer. Thoroughly wet the plants with this mixture, allow to sit for a few minutes, then rinse off with a mild stream from the hose. In addition, use a pesticide such as Malathion to control the whiteflies.
Reply:I have gotten black powder type stuff on all three of mine every year the past couple of years. I just left them alone and they were okay. Call a nursery and take a sample to them to check it out. Mine are still alive and have buds coming on. It has been cool here so they are a little late this year. But, as you know my black stuff could be different from yours hard to say. I know I was upset the first time I noticed the stuff and am glad they are still alive.

I re potted my gardenia and it looks to be dead can some one help?

i also added in m-grow in the dirt.

You may have shocked it with the m-grow (if that is a fertilizer). My suggestion is to repot again without the mgrow. Shake all the loose soil off the roots to get rid of all the fertilizer and repot with fresh soil. Cut all stems back to green. Keep it out of direct sunlight and water generously.
Reply:A friend gave me a gardenia last year and I decided to repot it right away. My plant lost nearly all it's leaves to shock. Gardenias hate to be moved, however, it will come back. Check one of the branches by scraping it with your fingernail and see if it is still green. If it is then it is still alive. If you can't find any green then you might consider a new plant. I hope your gardenia makes it.

It has sprouts, now what will help my gardenia bloom?

Temperature. Gardenia needs to experience cool temps in order to bloom. As soon as temps reach 65 degrees by day then move it outside in an area with filtered light, but remember to bring it inside if temps drop below 50 at night. Gardenias tend to bloom when temps are between 65-75 degrees. This is also a good time to begin fertilizing them. It also helps to leave them outside through the summer and into the chiller days of Autumn before bringing them inside.





Good Luck

Epsom salts and Bloom booster will help. What Spt said, she's brilliant.
