I have 2 jupiters joy..one has very green leaves..the other ...the leaves are yellow but otherwise healthy....that plant gets fed and is treated the same way as the other. It blooms like crazy! So is there something wrong with the yellow one or could it have sported?
Yellow leaves
Dr. Optimara :))
Did the two plants come from two different places ?
Leaves pale. They appear yellow or grayish in color. This is called chlorosis.

Chlorosis: Condition describing the yellowing of leaves. Typically caused by either insufficient light or an imbalance of essential elements. Also see Interveinal Chlorosis and Halo-ing
Leaves Pale: Possible Causes
Below is the complete list of problems which may cause chlorosis of the leaves.
Aphids
Bacterial Leaf Blight
Broad Mites
Chemical Gas Exposure
Cyclamen Mites
Fertilizer - Phosphorus Deficiency
Fertilizer - Potassium Deficiency
Fertilizer - Sulfur Deficiency
Leaf Bleaching
Leaf Mealy Bugs
Leaf Nematodes
Potting Soil - pH Imbalance
Privet Mites
Pythium
Root Burn
Root Nematodes
Root Rot
Scale
Soil Mealy Bugs
Spider Mites
Strawberry Nematodes
Sunlight - Not Enough
Virus
Whiteflies

My experience has been that Chlorotic leaves have some degree of green veining. (typically an iron deficiency) - I'm speaking of perennials/trees and shrubs of course, not AV's as I'm such an AV neophyte, but it could be Lorry that the yellow leaved AV is lacking some micronutrients.
I also read that a small dose of water mixed with Epsom salts will green up leaves. (folks don't try this at home... only kidding, Lorry, you'll just need to find the correct recipe if you use that since I dont know - but someone mentioned it on Violet Reflections the other day)
Hmm...No Allison :) they came from two different places.
I will give the espom a try and perhaps it will come back once it has had VF11 for a while.
if i already used vf-11 i wouldn't do anything for a while...usually 1tbsp of empson salts in gallon of water....
Yes and check roots well and crown in=between leaves. Soil light PH, may need more light,could even be a Virus
.Do what Bob said and check Dr. Optimara, make sure it is isolated/ let us know what happens.
Oh yes do you have picture of both plants
Lorry how did your yellow leaves turn out ?
The plant looks perfectly healthy but the leaves are still yellow ..so I am puzzled :)
I looked up yellow leaves the other day posted some where from Doctor Optimara.
Let me find it
Some reason for yellow leaves
Chlorosis: Condition describing the yellowing of leaves. Typically caused by either insufficient light or an imbalance of essential elements
Though it could have been Cyclamen Mites but also several other things for examples like;
Fertilizer - Calcium Deficiency ,
Fertilizer - Manganese Deficiency ,
Potting Soil - pH Imbalance ,
Pythium ( which I know was not your problem).
Just other symptoms for future people with the symptoms of yellow leaves.... i
definitely not lack of light.
Mites perhaps but I have had it for months and trewated it for big and so far it still looks SO HEALTHY other then the yellow leaves
I am really stumped since I am using VF11 so it should not have a nutrients problem
What is trewated do you have pictures of both plants ? Also can be do you have it isolated ?
Aphids
Bacterial Leaf Blight
Broad Mites
Chemical Gas Exposure
Cyclamen Mites
Fertilizer - Phosphorus Deficiency

Oh yes..it isn't nearly anyone else :) No but I can take photos when I take one of my mini papa for you tonight
Lorry is you just have one plant affected it may be a virus. In this case best to throw away pot dirt plant everything.
Makr sure everything that came into contact tools, scissors trays...are sll bleach and hot water soaked !
Don't save a leaf of a plant with a virus
Actually I have two that are VERY yellow...I forgot that the other one is..one of my lemon varieties..I got them both that way :(
I don't use any of my tools on plants in question. I was holding them for a bit to see if they greened up
Lorry this posting of yellow leaves made Feb 18th.
Did the plant come looking like this ?
ALso before using vF-11 DID YOU LEACH YOUR PLANTS AND NOT USE ANY FERTILIZER oops sorry for the caps , for a month. VF-11 will only work alone. Laurie said Eleanor told her to leach all plant to.
Your plant may also have come with a virus or many other things can casue yellow leaves. " Many"
If it's one plant be safe Lorry just throw it away :))
Yup I didn't use any other fertilizer and I leached them out.
Well jupiter I would not mind throwing away but would bother me to throw away lemon..but you are right Allison...I should
no sense in losing your whole collection worth thousannds of $$$
Lorry I find it interesting some thing Rob from Violet barn says about yellowing leaves , tight venters.
! One thing he talks about if the soil PH is off
>
And it may not be your soil could be what the plant came in.
Good reading >>
http://www.robsviolet.com/faq_page_6.htm#pH
He starts off saying yellowing in center and goes on to all yellowing leaves.
I noticed today that the new growth on them is green so not going to give up on them yet. I do think it was a nutrient issue and not a virus..but to be on the safe side they are no where near any of my collection :)
Lorry another questions answer on violet Barn I fount interesting..
See if your PH of the soil is off and plants are unable to asorb it's food it will starve and leaves turn yellow.
Also if a food being used has the highest number in the middle or bloom booster you foliage on your plants are also going to loose color, Rob sees no reason to ever use a bloom booster he does not even for shows. He says a healthy plant in a good enviromanet well cared for will bloom !
No chlorophyll means no green in the foliage. This is a perfect, though extreme, illustration of why a balanced diet is so important in growing healthy, blooming violets. Always feed your plants enough nitrogen. If you do use high phosphorus fertilizers, do so sparingly and when needed--never as a sole diet.
If you still have the plants. Maybe try re-potting it in new bleached pot, Sterile soil with proper PH. Feed it Eleanors give it plenty of light and warth, hunidity . Isolate . ( I keep some isolated plants on top of my stove lighted by my stove hood. lol
Just maybe the color will come back. I do know Jupitor's Joy does have light color foliage.
http://www.robsviolet.com/faq_page_1.htm#all%20green
It has a light green leaf...I have a healthy won and the leaves are like a kelly green color
Keep up the good work :)) I thought this might be of interest to a lot of us it sure was for me !
Lorry you know how we have read Av's with yellow flowers need less light and grow slower ?
Well I have grown Golden Thread for years and many times had problems with the crowns. Only to put leaves down, or take crown off and new healthy crown grows as the plant was healthy. But it always drove me nuts what was I doing wrong ?
Well I was reading on Violet Barn and certain varieties can inherit problems .
One is yellow flowering African violets varieties for example, are notorious for suddenly losing their center growth .
" Now I know why I have grown dozens of Golden Threads by leaf ( first one was a plant ) in the past couple years , they were healthy plants and gave me this problem . lol
It's not just yellow flowering Av's this was an example .
http://www.robsviolet.com/faq_page_2.htm#no%20center
I fount this very interesting wanted to share it !
certain varieties, suggesting that this might be a problem that is inherited. Yellow-blossomed varieties, for example, are notorious for suddenly losing their center growth

Oh that is good to know
(knock on wood) I have not had problems with any of my yellows yet but then again most of mine are still small.
Well if it happens it does not mean your plant is sick.
Right and that is good to know..though I will keep them seperated for the time being just to be on the safe side.
yes good idea.
Laurie here I posted a couple links from Violet Barn. His culture corner where people ask quetions is pretty informative . You can find interesting important information about everything .
I agree Laurie and Allison..I don't think it is a bug problem..I think it is a nutrient problem :)
Yes I was try to say all problems are not mites :)) I like the answers amd help Rob gives about them on Violet Barn culture corner under where people ask questions !
