Proven Winners® Fertilizers:
Your Formula for Success
We recommend using a Proven Winners® Professional Fertilizer with all of your Proven Winners crops to ensure your success. Based on your water results, we can recommend one of eight specific formulations. Each formula contains 100% FeEDDHA – the best chelated iron form available – for improved iron uptake at high pH levels and to correct iron deficiency.
Four Star will pay the $40 fee for new customers or customers that do not yet have a test on file.

How to Order
A current water test is necessary before purchasing fertilizer to ensure you are using the correct fertilizer blend. Four Star will pay the $40 fee for new customers or customers that do not yet have a test on file. We also recommend that existing customers retest every few years, but it is not required. Please contact your sales representative for more information.
You can access the comprehensive instructions and submittal form for the water test by clicking here. Once a water test is on file, you can order from Four Star by calling (734) 654-6420 or adding it onto your plant order with your preferred broker.
