Half of plant is yellow, while other half is green. What is it?

[socalgardengal]

I've noticed a few branches yellowing lately on one plant so I've been pruning them off. But today half of my plant was all yellow and the other half is green. HELP!!! Should I toss it? It's in a container with MG moisture control potting mix and I fertilize with MG as well. Bought those before I heard about all the other products out there.

Probably too much Nitrogen. MG is big on N.

Stop watering it, stop feeding it. Take pictures. Post them.

Is it possible you're overwatering it?

I water every 3 days and I use a chop stick pushed into them first to see how much water they need. I fertilize every 2-3 weeks a tablespoon to a gallon of water. Can't post pics as I just went out and cut the branches off 5 mins. ago and I can't post pics from my phone It's on a Jaune Flamme plant and it's producing lots of great fruit. Plus the leaves are curled up, I think because I prune too much and it hasn't been warm enough(high 60's) and foggy/ cloudy for a few weeks. The sun comes through for maybe an hour or 2. If it was from too much N, wouldn't it grow green and no fruit? Thanks for the help.

Christine,

Check out the threads in the Diseases Forum, especially the long one started by z_willis_d and compare his pictures to what your plant looked like before you cut the branches off. I suspect you have fungus issues. Tomato plants do not like June gloom in San Diego! My plants are suffering right now and I'm spraying them a lot. I just pruned off a garbage can full of leaves and branches today. Once the hot weather kicks in, the fungus issues will diminish.

Thank you Lyn, looking for the thread right now

I think this is what you want:

I'd start with late page-2 or page-3 for the full read. Some the earlier posts may be unrelated to what you want.

I'd take some pics of your plants and post them here or in my thread so we can try and triangulate your issue. There are some subject experts that might be able to help guide you in the right direction.

I've been reading your thread,I'm on page 5. Mine look exactly like yours do It happened so dare fast too. It seems to happen to the older branches first. Could it be from pollution in the air? I live about a block from a very busy street(more like a freeway) and the airport and all the deisel fuel in the air from the boats on the bay. Just a thought. I haven't noticed any mold growing on them,only on my squash plants. I use the milk solution for those and it works great!

[z_willus_d]

I don't think the pollution is bad enough to cause this problem on your plants, after all don't plants like carbon dioxide? Oh wait, I guess you're talking about the monoxide version. In any case, can you post a few pics when you get a chance so we can see exactly what you're dealing with. I think that there are more maladies than I can count on my digits that result in yellowing leaves on a tomato plant. That said, there a fair bet that you could have the powdery mildew issue that we're all fighting.

hi, Christine.

if half of your plant really looks like Naysen's photos i would recommend that you carefully pool it out leaving no roofs in the soil, cut the stem in the low area to see what it looks like ( both cross section and along the stem ), make and post some photos here, dispose of the plant, disinfect your hands and tools, and finally, google fusarium wilt to see if it sounds any familiar.

Ivan - She is growing in a container. I thought of fusarium wilt too as she said it was just on one side, but I thought Fusarium wilt was primarily in the ground?

[socalgardengal]

I can do that, just can't post photos from my phone. I would have to email pics to someone and have them post for me, which is a pain. I have 6 more jaune flamme plants so I can sacrafice one. I will do it tomorrow so I can see better. Also, my plants are in containers but they are on the dead lawn in the backyard. Could it be possible for virus'/ disease to come up through the bottom. I ask because I moved a couple the other day and it seemed like either grass or the tomato roots were attached to the container holes on the bottom.

seed, seedlings, hands, tools, weeds, infected organic fertilizers and soils, wrong kind of parasites at wrong places... just pick a weapon of choice there, each one can do it

growing in containers absolutely decreases the chance for it but it also doesn't eliminate it.
just as half green/half yellow absolutely suggests it but doesn't prove it. that's why i recommended to do a check, but, Christine, please note that the symptoms may often appear much ''lighter'' and not so easily and clearly seen as with most of the photos you could google there

A tablespoon of fertilizer to a gallon of water is the strength recommended for plants in the open garden, and it is way too strong for a potted plant, especially when the plant is growing in MG that already has some fertilizer in it. Only use a teaspoon per gallon, which is the strength recommended for potted plants.
