Hoping for the best

"I am still waiting to see what my tomato produces this year. Can't say that I see any drastic improvements yet. The instructions on the package were a little hard to understand."

"Big healthy tomato plants with lots and lots of tomatoes. I garden in a community garden with about 10 other gardeners and my tomatoes are always the first to harvest and last longer than the other gardeners. They say they are going to order some, only time will tell."

Tomato secret

"I had one Juliette tomato plant for all my tomato crop. It looked said and sorry with just a few blooms, I was ready to give up on it. After one treatment of tomato secret it came back to life and has provided regular tomatoes all season. It is the end of September and is STILL producing tomatoes!"

Tomato secret is out

"I put this product under my tomatoes and peppers(bell,jalapenos,and banana. ) Love the product. The main issue right now is the heat. We have been in tripple digits for 2 months,wich takes a toll. I live in deep south Texas."

Q&A

If I already bought a 64oz bottle of chicken soup for the soil do I really need to get the one for tomatoes
Tomato Secret is powder specifically designed for high quality tomato plants. It works great with Chicken Soup, so if you want the best tomatoes possible we suggest using Tomato Secret in addition to the Chicken Soup :)Hope this helps!
I have many shrubs and flowers growing next to my house, hydrangea, dogwood, peony well you get the picture. What can I use around them for robust bushiness and long lasting flowering
Chicken Soup for the Soil® is best for all flowering perennials, flowering trees, and flowering bushes. Tree Secret is best for all non fruit bearing trees, evergreens, and bushes. We hope you give it a try!
Can you use tomato secret on apple trees along with chicken soup for the soil?
It is best to use Chicken Soup for the Soil on apple trees. No need to use anything else. I would suggest using the Tomato Secret across the garden veggies, herbs, peppers, and melons :)
Can Tomato Secret be used successfully in Earth Boxes and if so, how many pounds for two tomato plants in one Earth Box?
It is best to use Tomato Secret in the soil for your tomato pants. Then water in Chicken Soup for the Soil®.
I do tomato plants in a pot, how do i use tomatoes secret
Great question! You can apply just like you would in the garden. Use 1 cup in the hole at planting, then top dress each plant with 1 additional cup after 1 month :) Cheers!

Frequently Asked Questions

What makes Tomato Secret® different from other tomato plant fertilizers?

Most tomato fertilizers are either a general-purpose granular fertilizer with a tomato label or a nitrogen-heavy formula that pushes fast leafy growth at the expense of fruit production. Tomato Secret® was formulated specifically for what tomato plants actually need. The 2-1-1 ratio delivers balanced nitrogen along with phosphorus levels and calcium designed to support strong fruit set and help prevent blossom end rot. Instead of synthetic chemicals that strip your soil over time, this balanced fertilizer feeds the microbes in your root zone so they can deliver nutrients back to your plants naturally. The result is healthy tomato plants that produce more and last longer.

Can I use Tomato Secret® on peppers, cucumbers, and other vegetables?

Absolutely. While Tomato Secret® was developed with the tomato plant in mind, the formula works beautifully across your entire vegetable garden. Peppers, eggplant, cucumbers, squash, and melons are all heavy feeders that benefit from the same slow-release nutrition. Apply about 1 cup per planting hole at the start of the season and side-dress monthly for best results.

When should I start fertilizing my tomato plants, and how do I know if my soil needs help?

Start by applying Tomato Secret® when planting tomatoes, placing about 1 cup in the planting hole beneath each plant. From there, side-dress around the base of each healthy plant monthly throughout the growing season. If you're unsure about your soil’s condition, running a soil test is a great first step. The results will show your soil pH and nutrient levels so you can identify any gaps. Tomato Secret® is an excellent foundation for any tomato patch because it delivers the nutrients plants need without the salt buildup that often comes with synthetic fertilizers.
