All plants should use this! I buy for pots indoors and outside. I actually bought a wide leaf fig tree interior use and will be using this soil for maximizing growth. This plant is a fast grower. I don’t want to over water so this should hold moisture until I water weekly.

Best potting soil available...

Im hesitant to share because it'll sell out faster bit this is great soil. I've tried so many and they have had algea, plastic, lots of bark, or smell awful. (Just what you want to plant your vegetables in, right?) I think the big difference is that Sam's keeps it dry. Whatever the reason, this soil is the best available!

Great soil, no transplant wilt, feeds for 6 months

I had several plants that were in need of repotting and this was about the best potting soil I could get 'off season'. I am VERY impressed at how well it is working and there wasn't even any transplant wilting. The plants (Angel wing begonia, Rosemary, prayer plant) are all doing GREAT!I am looking forward to using this to start some early seedlings for my springtime plantings it holds the moisture well and feed for up to 6 months according to the bag!

This is the only potting soil that I use on my african violets. It holds moisture in between watering so well. My plants grow huge with this potting soil, so I know it's good for them. I also use it for my green plants. I have never had plants come out so big and beautiful as I do when I use this product. It's well worth the money. I also like that there is no bugs, sticks, rocks , or mold in it like i have found in other potting soils.

potting soil for strong plants.

I learned to garden from my grandmother when I was a child. As an adult, I have had several vegetable gardens in which I grew vegetables and tomatoes. I plan to start to plant seeds in my grow tower soon. I live in northern California.

6 months of performance

This works great . My plants are happy and no need to fertilize for 6 minths. I find it great for starting perennial cuttings in the Spring to plant in the Fall.

Great product at a good price

This is my go-to potting soil (esp. because of the price) and was delighted with the order and pick-up option. Note that these bags can be a challenge for a single person to carry. Only concern I have is that Sam's runs out of potting soil in early July, before the potting season is over. Even when I stock up I never seem to have enough.

Miracle-Gro Moisture Control Potting Mix Review

I was really disappointed. The dirt inside the bag was dry and rock-hard—not what I expected from something labeled “moisture control.” It took a lot of effort to break it up and rehydrate it before I could even use it. Definitely not fresh or ready to go. I expected better quality.
