We switched to this weed and feed last year and have been very pleased with how well it works and how long results last. It kept our lawn looking great for many months with only minimal weeds. We definitely plan to use it again this spring and will probably even get by with just one bag, as opposed to the two we used in the past.

This is not my first time using this product. It works just as well, if not better than the brand name weed and feed. Members Mark is a reliable brand for less cost. My lawn was so lush and those wretched sticker burrs didn't make an appearance. Easy to use with good results. Great product.

Now that spring is soon to arrive our lawn definitely needs some TLC. Our lawn is prone to having weeds and different types of wild flowers from geese and other animals and yards nearby. My husband is always looking for ways to keep the weeds away so this Member's Mark Southern Weed & Feed is perfect. It has clear instructions on the back for how to properly use it and the recommended square footage space. I like that it is easy to use and controls a ton of different types of weeds while promoting grass growth.

Southern Weed & Feed 12M is an excellent lawn product that delivers high-quality results at a very good price. It feeds the grass while effectively controlling weeds, leaving the lawn greener, thicker, and healthier-looking over time. The coverage is consistent and easy to apply, making it a reliable choice for routine lawn care. Overall, it offers great value and performs exactly as expected.

Very easy, straight forward instructions. Wet the grass then apply. I have blue St Augustine and some weird feathery weed like grass is creepy into my grass. Plus odd little weeds can be seen here and there in my grass. This weed and feed does start working pretty quickly. I was happy to see some wilting and browning of the weeds. It's a good product at a decent price point.

This lawn care product both fertilizes the lawn and controls weeds with the same application. It effectively targets a long list of weed varieties and helps keep it green even in Florida's heat. The bag covers a huge square footage which makes the price per application a great value.

Have used this product on our older lawn which is very inundated with weeds. Have seen a marked improvement and recent growth were this product was used. This Member Mark product is quite comparable (if not better than!!) the brand names we have tried so often. Will continue to use to help restore our struggling lawn.

What I like most about the product is it's price per Oz and even price per square inch if you are wanting to be technical. Compare that to actual turf its a really good deal. I also like the cliam that it will add drought resistance and other important lawn protections. The only thing thag I wish was added would be a zipper of some sorts to reseal the bag.

Upon opening up and using this product, I do like that there's so much product in this packaging, it will definitely last me months and for the price it's a good deal. I also like the product colors, they're easy to see when I sprinkle it on my lawn. One thing I wish was that this bag was resealable. I cut a tiny hole in the bag though so I could control the amount of product that came out of it and that worked well.

I don't know if it works or not, I spread it around as the directions say and no weeds have grown, so either it works, or the weed fairy is picking weeds at night while I sleep.
