Review: An Excellent Fertilizer - I bought this in the spring after I planted my vegetable garden in the ground. The tomato plants and zucchini were somewhat yellow. Within a week of sprinkling this Fertilizer onto the soil, the plants became green and healthy. I apply it once a month to all my vegetables and this has been my most successful and healthy garden ever. I'm very pleased with this product. It's easy to use and you get a lot for your money. I have used about a half bag this year. That is about all I needed. It doesn't smell good but it's a lose and easy to spread, dry Fertilizer.
Review: Good stuff - My plants love this stuff.
