    Too early

    Just put some sulfur on my tomato plant today. Too early to tell if it's the boost my maters need, but it's sulfur, can't go wrong with that.

    Sulfur review

    Your product was cheaper than what I purchased locally. However, when shipping costs are factored in, I bought the product significantly lower price at a local feed store. My 2 star rating is for the high shipping costs.
