What is the mixing ratio of Peters Excel 15-5-15 Cal - Mag Special Fertilizer? parts per gallon?


The mixing ratio on the Peters Excel 15-5-15 Cal depends on the target fertilizer concentration after dilution you are looking to achieve according to the product label.  For spray cans, it does say 1 tsp for 1 gallon of water.
