Do you need to support the tomato truss when the tomatoes are getting bigger so that they don't snap the truss stem?
In some cases, yes, especially where the fruit can become quite heavy on larger tomato varieties. You can minimize the burden of weight on the trusses and help hold them up by using truss ties and clips. Clips extend from the truss to the tomato plant's main stem or latch onto another support structure such as a tomato cage.
Tomatoes are my favorite so I've a huge collection of tomato plants in my garden. From some time, these plants are being ripped off while grown-up. Please help me to avoid such disease. Thank you!
Tomato splitting is not caused by disease but by environmental conditions (temperature change, lack of water, etc.). Here is an article that explains more: https://www.gardeningknowhow.com/edible/vegetables/tomato/tomato-cracking.htm

No matter where I look online to find an answer on the growing temperatures for tomatoes, I invariably run across what, to me, is a conflict in what the writer of the article is advising. This article presents the same question for me. Let me explain. "Most tomatoes are warm season plants and should only be planted after the danger of frost has passed." The question is, is that statement correct? I read it to mean that if I'm sure that the temperature will no longer drop below 33 degrees, it should be okay to plant. However, the article also states "There are specific tomato varietals bred for cold hardiness which will tolerate conditions at or below 55 degrees F. (13 C.)." Thus, my confusion. As a first time experiment, I've successfully began growing tomatoes from seeds and now have the 'seedlings' ready to plant. I'm in area 6b. It is now approaching the last frost date (May 1) and The Weather Channel's 10-day forecast has the approximate day temperatures generally in the mid 60s and the lowest night temperature at 39 degrees. I'll ask Laurence Olivier's famous question: "Is it safe?"
I would recommend waiting a bit longer before you plant those tomatoes outside. You should plant tomatoes outside when the overnight lows are consistently above 50F.

My young seedlings of about 5 weeks wilted almost over night. They look better now but some of the leaves are dying around the edges and drying up. What could the problem be?
This is most likely caused by over or under-watering. Either scenario would cause the symptoms you described. What are your watering practices? You should water your tomato seedlings enough so that you don’t let soil dry out or seedlings wilt. The soil should be kept lightly moist, not damp or soggy.
On a more serious note, however, it could also be "damping off" disease, which thrives in wet conditions (caused by over-watering). More information on damping off” can be found at the following link:

My kids ate some of the fruit, what should I do? We found our tomato plants have Alternaria from the diagnosis found on your site. They are planted in planters with strawberries. The strawberry plants look ok, but the strawberries seemed deformed, very small and ripen very fast. My toddlers have been eating what few strawberries we've had. Now I am concerned that since the tomato plant has their fungi, so does the soil, and it has spread to the strawberry plants. Knowing that my kids have eaten fruit possibly infested with a fungi makes me worried that they have been exposed to it. What should I do for them (kids)? We are throwing out the plants/soil/planters and starting fresh. I'm just worried about my kids' health. Thank you!!!
It's supposed to hit 28-30 degrees this weekend, cover my tomatoes or no? Living in the Rapid City, SD area - the forecast keeps changing from 28 to 30...the plants are doing so well. Can I just cover with a plastic tarp? Supposed to hit that temp for 3 days through the weekend.
Tomatoes do not like temperatures below 40-45 degrees so I would recommend covering them. I always say better to be safe than sorry!

Watering tomato plants from above can cause disease and pest problems. What about the rain? Why doesn't rain cause disease and pest problems in garden plants?
Oh, but it does. Mother Nature is just as much to blame as we are. The watering recommendation not to water overhead is given to gardeners so that they don't further encourage potential disease and pest problems.
