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.

Received a refund
I purchased the 4-year protection plan offered at the time I purchased a refurbished printer. Seven months later the printer failed, so I went searching through my Amazon orders for my protection plan and located it. Once I created an account on Asurion's website it showed the the plan but it was not attached to a specific purchase, so I had to locate and upload the invoice for my printer. Once that was done, the policy still wasn't linked for some unknown reason. I proceeded to start the claim anyway stating that my printer had failed and I received an immediate reply stating that a box would be shipped to me for me to return the printer for inspection/repair. After a week I hadn't seen any additional info so I called their support phone #. The service was very good and they had to create a new case to replace the one I started online, and they assured me that a shipping box would be sent. About a week later I did receive the box with a prepaid shipping label to return the item by UPS. I packaged the printer up and sent it off. I received updates stating that they received it, were looking at it and attempting repairs. Everything appeared to be going along well, then out of the blue they sent me a notification of a full refund in the form of an Amazon gift card. Overall I'm satisfied and I'm glad I purchased the coverage.

Worst Experience of my Life
My Epson printer had problems with it's software in early mid April, while trying to resolve the software glitch which I could not, I found that every picture I had scanned for some time had lines running through it and no cleaning process or other process that Epson had would get rid of it, and everything I had scanned for my project, was ruined. I sent the machine to Asurion following their instructions and explaining the issues. They sent it back to me after a month saying they had double checked and fixed everything, I spent some time setting it all back up, only to find that exactly the same two issues were still present and the machine was unusable. I sent in a second request, this time they sent it back to me a month later saying they couldn't find anything wrong with it. Hooked it up again, same problem. I complained numerous times asked for them to warranty the item; they would not unless I sent it back to them and they kept it and then they would give me a credit on my amazon account to buy a new one. I packed it up and drove to UPS a third time and mailed it back to them, after about three weeks they sent me a note that they had it and that they were sending it back to me as they couldn't find anything wrong. Three times I ha filled out their entire sheet with product, date of purchase, problems detailed, receipts, picture of the lines in the photos that it was making over all the scanned photos. Then after two weeks of back and forth they sent me a message telling me they couldn't warranty it until I filled all this information out again on line. Then they told me they couldn't read the tiny print off the receipt printed off the Amazon site, which I cannot change. I then blew up the receipts and circled everything and sent it back to them again...of course they already had now five copies of this same information, they had paid for postage three times to NY and back to fix it and they still aren't able to process a payment to me????? Finally I get a call from a gentleman telling me that I will have a credit to my Amazon Card in 72 hours. Great. Then he calls me back the next day and says the warranty team has decided they would not warranty the item and credit me but they will mail me a check in 7 to 10 days. After over four months of this I received a check...will it bounce? I don't know yet. My project that I was working on was for my mother's Celebration of Life, I could not do what I wanted to do for her, this caused me emotional pain, as well as the obvious frustration of four months of aggravation and complete and total ineptitude on their part.

Simple and not Drama claim process.
’ve had Asurion coverage for a couple of years and never needed to use it until recently, when my pool salt cell (less than two years old) stopped working. I had purchased it with an Asurion protection plan, so I contacted them to start a claim.
The process was simple and straightforward to follow. In the end, they honored the plan and covered the cost of my salt cell based on the value when I originally bought it. They issued me a gift card that I could use on Amazon for that amount.
While prices have gone up and a new cell now costs about $200 more, it was still definitely worth having the coverage. Overall, I’m satisfied with how the claim was handled.

Love this protection plan
Quick and easy. My daughter's cracked her screen on her phone, as soon as it happened I went on the app, filed the claim. Ten minutes later I received the email with the shipping lable. The following day I dropped the phone off at ups and 4 hours later I received the digital gift card. Ive filed several claims since getting the protection plan and with four kids its definitelysomething im glad to have especially since i dont have to buy a protectionplan for each item now. I have filed claims for electric scooter the stoped working for no reason, my son's phone stopped charging, my oldest daughter cracked her phone screen, my son's video game controllers up and died and each time it was quick and easy and no fuss
