Something has eaten all the unripe tomatoes from all my 5 plants
I have one determinate, 2 undeterminate, 2 cherry and 1 roma.
To figure out what's eating your fruit, and what to do about it, you're going to need to play detective. I'm sending you an article about common pests. You may need to practice several controls, e.g. sticky traps for mice, pan of beer for slugs, spray of neem, soap, or Bt product for worms. https://www.gardeningknowhow.com/edible/vegetables/tomato/tomato-plant-problems.htm
