Where I the world are you?

What did you use as potting soil?

Was a plant nutrient used?

I am in Orlando Fl, and I used the 5-1-1 mix, I did not use a herbicide. I did use Jacks 20-20-20, 1 tbl to 2 1 gal of water and poured it in the soil. I also sprayed a solution of Daconil mixed 1 tbl per gal of water. In Florida we must keep up with the fungicides due to the high humidity and all the disease that we get here.

Did a neighbor use herbicide?

If not, what's the incidence of virus in Florida?

Please post an image of the entire plant.

Yellowing of a plants leaves is often due to a lack of the plants ability to make chlorophyll, also known as plant chlorosis. There are many reasons why this happens but most are due to plant nutrition. Perhaps this link to an article on plant chlorosis may be of some help.

Jean, the neighbors did not use a herbicide, and my other tomato plants are doing ok. it could be that I mixed my fertilizer to strong. Here is a picture of the entire plant.

I wouldn't fret too much about some yellow leaves here and there. Your toms look fine to me. My toms can sometimes look pretty shabby as the season progresses.

That said, you want to avoid killing it with kindness. You might be getting some fried roots with a small black pot in direct sun. Water might not be penetrating the newspaper barrier on top of the soil. Tomatoes are resilient enough and do well enough if we just leverage their will to live. :)

I grow toms year round in EarthBoxes using Dr Earth organic tom & veg fertilizer (5-7-4). One of the tenets of organic gardening is the use of water insoluble forms on nitrogen (Dr Earth fits the bill). Weekly/weakly fish emulsion and such is fine as well as a supplement, but not necessary.

Once you said you were in Orlando, I realized you have something that the rest of the US doesn't get (that I know of) It is called TYLCV (tomato leaf curl) It is a virus from the Caribbean and only affects South Florida (that I know of) I am in Tampa, and when you get this, it destroys the plant. I am online now, seeing what I can do about it. Here is a link (btw: hope this is not your problem, and let us know the outcome) http://www.freshfromflorida.com/Divisions-Offices/Plant-Industry/Science/Florida-Plant-Viruses-and-Their-Inclusions/Florida-Plant-Viruses/Tomato-yellow-leaf-curl-virus-TYLCV-in-Tomato

This looks like my plants already pulled 2 off them they died what can i do. I have nice green tomatoes on the vine

I live in St Pete Florida, and I am having issues with my cherry tomatoes getting yellow leaves at the very very top, where new growth occurs: I will attempt to upload an image...I do grow my plants in large black pots, they get watered once a day, and I use a 777 fertilizer every other week.

I use my own compost dirt in the pots... I've never had the dirt tested... are there ways to get the soil tested with a kit, or something, other than sending it off in the mail to USF in Gainesville???

Is the yellow on these plants a concern?? - julie

Did you ever find out why your tomatoe plants were yellowing? I have the same problem.

Yellowing of tomatoes is caused by lack of nutrients or harmful insects. Before planting tomato seeds in pots, you should mix the potting soil with worm compost. this ratio can be 3/2 of the pot size.

If you do not want to use chemical pesticides in the fight against pests, you should mix 100cc Wood Vinegar in 1 liter of water and give it from the leaf.

If you repeat this application every 15 days, your tomatoes will return to normal.
