About a month or so ago I planted 4 tomato plants 2 were the bush kind and 2 were the tall kind. Well the bush kind is growing some nice tomatoes but the tall ones don't even have flowers yet! They are in good soil and are regularly watered. Am I doing something wrong or am I just really impatient? I'm new at this and bought the same tall kind as last year and those did great! Any advice would be helpful!!
