I recently tried Member's Mark Potting Mix for my indoor and outdoor container plants, and I am incredibly impressed with the results. The built-in moisture management makes it so much easier to maintain an even watering schedule without worrying about over-saturating the roots. I also love that it feeds my plants for up to 6 months, saving me the extra time and money I'd usually spend on separate fertilizers. Overall, it's a high-quality, low-maintenance soil mix that has kept my flowers looking vibrant and healthy.

So far, so good-Outdoors gardens

Multiple gardens with variety of flowers & mint (trying to keep pests away). It has vermiculite (little white styro looking specks) that aerate the soil. When dry, it's light and fluffy, when wet, seems to hold the water around plant. So far, so good.

The potting soil was easy to use in my garden. The mixture has all the nutrients necessary to keep my flowers in great shape for the season. The mixture even has a wetting agent to help apply even moisture when I water the plants. I would certainly recommend it for all your gardening needs.

This potting mix came in a generous 65-quart bag for a really good price. The soil feels light and well balanced, making it easy to use for both indoor and outdoor plants. My plants adjusted quickly after repotting, and the mix holds moisture well without becoming too compact. Great value for the amount you get, especially if you have several pots or a larger garden project.

recently switched to this Member's Mark Potting Mix for my indoor and outdoor containers, and the results have been wonderful. The moisture management feature is a game-changer, keeping my plants perfectly hydrated without the constant guesswork. Plus, knowing my flowers are fed for up to six months makes maintenance so much easier. It is an incredible value for the price and the quality is top-notch!

Potting mix review

I made a big planter with this potting soil on Mother's Day, and it really made the plants--all four--come to life. The product is amazing in that it really helps the plants bloom and reach their natural potential. I put in a summer scarlet lily, blue salvia, polka dotted plant, and a begonia. The plants after a month had no disease and were flourishing, and I would buy this product again with no hesitation.

The Member's Mark Potting Mix is an absolute steal for anyone with a lot of ground to cover, as the bag is gigantic for the price and offers much more volume than standard garden center brands. I was pleasantly surprised by the quality of the mix, which I found to be a very decent, reliable medium for my plants. The texture was impressively light and fluffy right out of the bag, making it easy to handle and distribute without any heavy clumping. It provides a great balance of moisture retention and aeration that has kept my plants looking healthy and vibrant. If you are looking for a budget-friendly way to fill large containers or raised beds without compromising on a good growing environment, this is a fantastic option.

I like the amount it brings in one bag. I just started my first ever greenhouse and this is enough for the amount of plants I have at the moment. I think this can last me a while maybe even until next spring. I like that it is light and fluffy but as soon as I water my plants it soaks it all in. I really enjoy this potting mix.

Garden soil not potting soil

I was hoping this would be similar to the Miracle grow that Sam’s Club usually carry’s but I was very wrong. This was so full of small sticks and bark and twigs it made it very unpleasant to work with. After about 1/4 of the bag I gave up and used it to fill a couple spots in my yard and went out to purchase an actual potting soil.

Worst potting soil ever

On sale so thought I’d give it a try. Terrible soil, dry and mixed with many pieces of wood. Ended up dumping it out in the back of the yard. Checked the bags and they were dated Sept. 2025. Be wary of this product.
