We just planted about 25 tomato plants and all of them all of a sudden have yellowing of the leaves. We were very careful to put the best soil in so we do not think it's that. Also, we water the plants in the morning and in the night and it gets plenty of sun. Any other reasons why the leaves are turning yellow? It's definitely from now enough caring because I take very good care of my garden. HELP!
Most likely it's from shock, though tomatoes turn yellow for many different reasons. You can treat them like they have transplant shock to help them recover better. This article tell how to treat plants with transplant shock:

Tomato plant is huge with a lot of blossoms but no tomatoes. The tomato plant next to it is about the same size, and it has a few tomatoes on in. What's wrong?
This could be due to many things like fertilizer, weather, or (I think in your situation) poor pollination. This article should help: https://www.gardeningknowhow.com/edible/vegetables/tomato/tomato-blossoms-no-tomatoes.htm
Almost all of my tomato plants suddenly have curled upwards. How do I know if this is due to an infection? The plants have not yet started giving tomatoes, but were doing well up until a few days ago. The weather has been very hot during the day and mostly warm at night until early morning. You say that curling will not affect the growth of the plants or fruiting but to destroy if they are infected. The infection can spread so destroy them. It is pretty much all my tomato plants (about 50). Please advise.
You may want to wait and determine if the leaf curl is viral caused. If the plants become stunted and stop growing you have your answer.
If they continue to grow, flower and form fruit, it could have been environmental.
I understand the investment of money and time in 50 plants.
I myself may even try a treatment of something like Neem Oil. It may be worth the try.
Best of luck.

We used string to tie up our tomatoes and the string broke off and they are everywhere right now. What is the best thing to use to hold them up or should we just leave them alone now that they are so big and tomatoes are already starting on them?
I have found strips of pantyhose to be quite useful for this. They will stretch as the plant grows and won't break or cut onto the plant stems. The use of cages is another option, depending on how large the plants are at this point.

You should definitely string then back up. Tomatoes left to grow on the ground are more susceptible to rot. Its never too late to restake and string them. We usually use twine to hold ours up but if you look in the gardening section at your local stores they have all different kinds of options. Im frugal so I like yo use what I have on hand. Last year my step dad abandoned his tomatoes without staking so I used some old tent poles and regular curling ribbon for gifts and that did just fine. This year I used the tent poles and weaved them through some old fencing wire and gardening twist ties to support my tomatoes.
I have what appears to be leaf curl in my tomatoes, potatoes and sunflowers. One tomato plant already appears dead and others badly injured. Several potato plants, only a week and a half out of the ground, also appear badly affected. Last year this was confined to the sunflower plants.
This could be a white fly infestation, verticillium wilt, or environmental issues.
Crop rotation is an important practice and can help reduce or eliminate some of these damaging plant viruses.
Since you had issues last year with the sunflowers, I would also suggest a soil test.
This will help you determine what fertilizers would be most beneficial to your garden.
You may also want to treat the plants with Neem Oil. This works as both a fungicide and insecticide.
Here are a few links for you.

I have already planted my garden but got a big storm. Some of of my plants have the tops broken off. Blooms on some of them, will they produce at all? I have removed some to replant elsewhere. How long do I have to do that? I still harvesters to be removed from my garden yet.
As long as the rest of the plants are ok, then they should recover just fine, though it would hurt to treat the plants with neem oil to guard against any pests or fungal issues now that the plants are stressed. It is a good idea to remove the broken/severed branches. New branching and flowering should take place soon enough.
How much water does a tomato need? I have read the articles that discuss frequency and time of day but ignore quantity. I have located the university papers that discuss irrigation and transpiration and are written in Martian. I am just trying to water 7 outdoor tomato plants for absolutely optimum results. Can you help me?
There is no one set amount for this. There are dozens of factors that can influence how much water a tomato plant needs at any given time. These factors can include age of plant, size of plant, type of soil, current temperatures and humidity, state of fruit and amount of fruit as well as weekly rainfall.
A general baseline is considered to be 2" of water a week for a plant in the ground (more often for container plants). Due to all of the factors above, this amount may be too much or too little for your tomato plant. Instead, it would be wise to depend on a water gauge or an indicator plant to tell when you need to water your tomatoes. Impatiens make a good indicator plant to put near your tomatoes as impatiens wilt immediately when they have too little water, thus indicating that the tomatoes also need water.
