I planted some tomato plants in August in pots with 70% soil and 30% organic vermicompost. Plants started to fruit from mid November, but even today those tomatoes are very small and green (and hard). It has been 1 month and they are not turning into mature ones. Are the plants missing something?
Is 30% vermicompost not enough or should I use some NPK fertiliser?
What is the usual time for tomatoes to turn red and mature?
