Dry Magnesium Fertilizer for Palms, Citrus, Trees, Shrubs, Roses, Vegetables, Annuals, and Turf
Southern Ag Magnesium Sulfate Fertilizer is a dry, fertilizer-grade magnesium source designed to help correct magnesium deficiency in a wide range of outdoor plants. Magnesium is an essential secondary plant nutrient that supports healthy green color, strong plant growth, and normal chlorophyll production.
Magnesium deficiency commonly appears as yellowing between the veins of older leaves while newer growth may remain green. On palms, symptoms often begin as yellowing along older fronds or leaflets, while the center portion of the palm blade stays green. If left uncorrected, older leaf tips may turn brown and remain damaged.
This easy-to-apply dry fertilizer helps supply water-soluble magnesium directly to the soil. Simply spread the recommended amount over the treatment area and water in thoroughly. No tank mixing or spraying is required.
