Tomato Results

A garden with 20 tomato plants, both heirlooms and hybrids was fertilized three times with All Purpose Plant Food 20-20-20.
In approximately two months, the 20 plants produced over 40 quarts of whole tomatoes. Royal-Grow not only increased production, but it also promoted dark green foliage throughout the year.

2013 FFA Greenhouse

The following pictures were taken on April 3, 2013. Royal-Grow increases plant growth and root mass.
All of the plants were fertilized a couple of times with All Purpose 20-20-20 when they were first transplanted. They were fertilized with Organo Choice 24-8-16 from the time they were transplanted until they were sold.


After application of Royal-Grow, the plants in the greenhouse look more vibrant and they have a darker color. The Royal-Grow fertilizers have helped all of the plants grow. We will definately continue using these products in our FFA greenhouse.
