I just started a vegetable garden bed this year and I have been overwhelmed with so many things to do and not do, use this or don’t use that. Some of my tomato leaves were curling and not growing much. I finally decided to try this product out on my different variety of tomatoes as they just started to flower. I really liked that it could also be used with neighboring plants such as my zucchini, peppers and flowers so I applied it to all of them. 2 days later my tomatoes start to fruit and leaves look better! Sunflowers:I’m also growing mammoth sunflowers which are about 3’ tall and their lower leaves have always been droopy even after watering them so I applied the product to my flowers and the very next day, my sunflower leaves were no longer droopy and they were more sturdy and perked up!!! THE NEXT DAY! I don’t leave many reviews but if someone is dealing with the same issues that I was struggling with, I hope it helps! Happy Gardening!

I bought this fertilizer specifically for tomatoes and other fruits, and so far I think it has given good results. My tomato plants look healthier and more developed compared to before using it. I’m still in the process of growing them, so I can’t speak long-term yet, but up to now I’m happy with how the plants are responding. It was easy to use and didn’t cause any issues.

The tomatoes went crazy. Is it due to this fertilizer? I have no idea, but I will buy it again.

Worked great

This was a great addition to my tomato plant. I believe I was using too much Nitrogen causing the plant to leaf and not produce as much flowering. Once I started adding this my plant began to flower more and produce more tomatoes. I just wish I used it earlier in the season. It also works great if you have bell peppers. Great purchase

This stuff has worked wonders on my garden this year. Using it every two weeks one the fruiting season began and plants were large enough. I use a high nitrogen and low phosphorus/potassium until plants are mature enough to bear fruit and then I switch to this. Consistency is key and will help yield huge harvests! Pulling that many cucumbers off of four plants every other day. Tomatoes are just as good and we are having trouble keeping up with just 2 Tomato plants. Went from using nothing last year to using this for the first time and my harvest so far is easily double last year's. Next year we are going to have to cut back on the number of plants because this fertilizer is helping produce more than we can eat AND can!
