Southern Ag Magnesium Sulphate is formulated to prevent and cure magnesium deficiency on shrubs, trees, palms, annuals, and turf. Contains a fertilizer grade magnesium sulfate that inhibits the emergence of weak-looking, tiny, and yellowish leaves called "frizzle-top," causing the immediate death of the plant. This highly effective soil conditioner is proven to make most plants return to its original dark green color after the application when used at the first symptoms of the disease. It is perfect to apply to plants that are prone to manganese deficiency such as Hibiscus, Poinsettia, Date Palm, Podocarpus, Orchid trees, and Citrus trees. Guaranteed to acidify soils with low risk of staining. For best results, avoid mixing and spraying. Use as a dry fertilizer or spread over the treatment area. Sold in a 5-lbs. bag.

Magnesium deficiency is a common problem with palms, shrubs, and many other plants. Symptoms on most plants first appear on older leaves as yellowing in between the leaf veins while the new foliage remains green. Most plants respond well to the addition of SA-50 Magnesium Sulfate and will return to a dark green color after the application.
In palms, magnesium deficiency first appears as yellowing along the outside margins of older leaves (fronds) while the newest leaves remain green. The problem is easily solved by an application of SA-50 Magnesium Sulfate. This should stop the problem from progressing any further, although older, magnesium deficient leaves will usually remain yellow and damaged. After the application has been made, wait for 1 to 2 weeks before removing damaged leaves. When pruning, be careful not to injure the “heart” (center of the palm). Preventative applications should be made to ensure no further damage to the palm.
Most plants and palms are susceptible to the deficiency, but some of the most susceptible seem to be the Canary Island Date Palm, Date Palm, Pygmy Date Palm, Pittosporum, Podocarpus, Poinsettia, Hibiscus, Crepe Myrtle, Citrus Trees, Many Vegetable Plants, and Orchid-Trees.
NOTE: The problem is usually a sign of simply low magnesium amounts in the soil. This is because the element is used in large amounts by most plants. The soil pH can also be a factor in magnesium deficiency and should be checked and maintained at about 6.0 - 6.5.
