Grower Select Mag Triple Iron 18-6-18
Great choice for Petunias, Calibrachoa, Pansies, Vinca, Verbena and other plants that benefit from extra iron. Three sources of chelated iron, potential acidity of 339lbs CaCO3, and extra magnesium ensure your plants have dark green foliage. Excellent if you have high alkalinity irrigation water because it acidifies and also adds Mg to keep your Ca to Mg ratio in balance.
