Produced beautiful and delicious tomatoes.


We moved to a spot where we only had deck space to grow tomatoes. We were thrilled with the quality and quantity we got with this tomato growing kit which included this fertilizer. We're on our third year growing beautiful tomatoes .

Great Fertilizer for Your Tomato Plants.


The best fertilizer around, and it's organic.


Berlin, NH

Works great so far


I bought this last season but didn't use it for some reason. My garden was plagued with aphids last year and my tomatoes only did OK. I planted 7 tomatoes in March (I am in So. Cal) and decided to give this product a go. My plants are doing amazing so far. The plants are large and healthy and pest free (so far) and leaves are bright green and there are tons of blooms so far and even some tomatoes. I am going to buy a 5 lb bag and use it throughout the season. The one plant I didn't use it on (ran out of the small 1 lb container) isn't doing nearly as well as the rest of them that all got the fertilizer.

One of the best organic fertilizers I have used.


One of the best organic fertilizers I have used. It works with transplants as well as mature plants. I've seen a bump in fruit production with a decrease in pest damage (as the plant are heathier). Would like to see this in a bigger package for larger producers.

Won't grow tomatoes again without this fertilizer.


We recommend this fertilizer to all our friends. If you want fast growing, healthy tomatoes, try this fertilizer. We plant our tomatoes and peppers in self watering containers and they are the envy of the neighborhood.
