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.

Works if you need help. Not a miracle in a bottle.
Size: 1 Count (Pack of 1)
It has worked every time I've used this product. Won't fix a damage catalytic converter but will help you pass the test if your car almost passed.

Worked like a charm.
Size: 1 Count (Pack of 1)
Used it as directed. Down to an eighth of a tank. Poured it in and added enough gas to get back to one half a tank. Wanted to get it mixed in really well. Immediately jumped on the interstate and ran 75 MPH for 40 miles. Stopped and filled the tank and when I restarted the engine, the light was off. Coincidence? Not a chance. Light had been on continuously for weeks. AutoZone said I needed a catalytic converter. Nope. One thing I found out the hard way. If your gas filler has a flap at the top, make sure it is easy to push aside. Mine had a little release button near the top that the filler hose would depress before the flap would release. Dumped the first bottle right on the ground. Twelve bucks wasted. No one to blame but me, I guess. Still a bargain, even at twice the price.

I received it March 14.2026 and used it on March 15.2026 I took a picture on Sunday before I entered it into the gas tank engine light was on at that time. Today is March 17.2026 and engine light is still on. The truck was driven for one hour on the 15th 45 minutes on the 16th and 50 minutes on 17 March. Still the engine light is on. Got home parked the vehicle took a picture again to show engine light is still on product guaranteed it was shut it off, but unfortunately product does not work.
