## Description

desertcart.com : Farmer's Secret Tomato Booster Fertilizer (8oz) - Super Concentrated - 3:8:7 Ratio Fortified with Humic Acid, Iron and Calcium - Grow More Tomatoes : Patio, Lawn & Garden

Review: Great on tomatoes and neighboring veggies/flowers - 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!
Review: Seems to work well for tomatoes - 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.

### ⭐⭐⭐⭐ Seem to be ok but needs more Calcium
*by P***R on July 20, 2025*

Appears to be working, But it needs more Calcium in it!! The label states it has it but ? but it has very little to none , I have to use CalMag with it. I'll stick with my Espoma Tomato Tone it's a complete Package
