This is a huge bag of potting soil! It has all the instructions you need to know on the bag itself. It even tells you what size pot you have and how much soil you will need. This soil will feed your plants up to 6 months This is a great product. I will buy again and again.

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.

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.

Considerable Amount of Large Wood Chunks

I have mixed opinion on the Member's Mark potting spoil. Cost per cubic foot is about the same as large box store brands. This bag seemed to have decent fines with lots of perlite. Moisture retention has been excellent. The concern is the number of large chunks of wood included in the product. It will work great for full grown plants but needs filtering for seedlings.

I love this members mark potting soil! This is not my first time buying this product and I'll be back to get more. I've used it to start my seeds and I've used it outdoors in my yard and either way my plants do great. I have used other brands but members mark is absolutely great.

I love that Member's Mark Potting Mix can be used for indoor and outdoor plants. The instructions on the back of the packaging is a plus, because I'm not a seasoned gardener but would love to become one. Being regionally formulated would ensure that my plants should do well. The potting mix was black and rich and had a rich texture that was easy to apply and the ease of use means I'll be purchasing more potting mix in the near future.

More Mulch Than Soil

More mulch than soil. Drys out quickly so need to water plants more often. Just does not compare to the Miricle Grow potting soil Sam's used to carry. :-/

Good Stuff

Purchased a bag of this potting soil just to check it out. For the price this soil is excellent. No large wood pieces. Soil number look good. Good deal will buy more.

If you're new to planting like me, this is a great starter mix for potting. It can be used on pretty much any kind of plant and it's compatible with both indoor and outdoor plants. I like that it guides you on the back by telling you how much soil is needed for different sized pots and gives a guide on how get started and actually keep the plants alive. It will definitely last me a long time, I plan on giving some to my mother so that we can be plant buddies.

The members marked professional quality potting mix is good for both indoor and outdoor container plants. I'd like the price point versus the name brands. This does just as well with my plants. It has enough food and fertilizer in it to feed for up to six months and it has moisture management in it. This is an amazing value for something really good quality. I'm going to buy many many more bags of it this spring.
