First I need more details. Do you mean no seeds sprouted at all or that the seeds came up then died or had no produce? Did you mean you used plant starts instead of seeds and they died? Or did you just have a very poor harvest? Perhaps a photo and more details about what type of soil and light the area receives will help me to solve this mystery. Don't worry there are no perfect gardeners and we all learn from things that go wrong. We will solve this. Keep growing, Marianne Binetti
