We’re sorry to hear about your experience. This mix is a premium blend of peat, composted softwood bark, composted forest products, perlite, fertilizer, and a wetting agent.

Very good potting soil.

I think this is a lot better than miracle grow. Actually dirt. No big chunks of bark.

Terrible

Too many large wood pieces. Even found gravel in it! So different from last years mix. Why would you change ? I know it is guaranteed but I’m 72 and lifting it 3 more times is out of the question. So disappointed.

Do not buy

Who is writing these positive reviews?? It's a big bag of mulch. I lost dozens of seedlings to this terrible "soil". Thanks for killing my Spring excitement with your death soil.

Members Mark Potting Mix

Bought this for the first time & am very disappointed in the quality of the product. I use Members Mark products all the time & am usually pleased. This potting mix is mostly mulch & bark & the plant I used it for has not grown & is an unhealthy looking pale green. Another plant I planted at the same time in another mix is dark green & healthy.

Sams potting soil

I like the soil. I have used for several yrs. The tree stuff keeps it lighter weight. I add 1/2 bag of perlite to each bag. Mix in a large covered container. I add sevin granules and mosquito bits to each container to stop gnats or any other bugs. None of the bagged potting soil is perfect. U have to work with it. Add what helps yur plants. I only use for my outside plants. I my the frog stuff for indoor plants. I also add some frog stuff with the sams brand also.

MM potting Mix - Poor Quality

This MM potting mix is very poor. It does not work for seedling, and all my seedlings are not germinated. I also put it in the pot with Jobes vegetable organic, garden lime, meson salt and calcium nitrate(4-1-1-1 tablespoon ratio),, and found it not useful for plants. I waisted money for this mix.
