This product is made by J. R. Peters, Inc. They make a number of different Peters brand fertilizers. When I worked in a greenhouse, this was the fertilizer that we used in the watering system. It is designed to dissolve completely. It also contains trace elements. This is an 8 oz. container.
This is a water soluble plant fertilizer. This is special designed specifically for African Violet to promote healthy growth, intense flower color, and large numbers of flowers. The standard constant feed method is to use one quarter of a teaspoon per gallon of water. It is easy to use an empty milk jug to mix water for your plants.
