Someone sayes i need iron in my veggie garden?

Question:to help my tomatoe plants grow it..
is this true and where do i get this?

Answers:
Actually it is more likely that your tomatoes need calcium rather than iron. Tomatoes that suffer from blossom end rot (where the bottom of the tomato turns black and gross) which means that your soil is deficient in calcium. There are products at your local garden center to help the problem.
