this miracle-gro works great
I have tried two guerdon's one with this Miracle-Gro and one with out the Miracle-Gro and the one with I had 25 tomato plants and got over 800 tomato's and very nice size and one with no Miracle-Gro I only around 400 tomato's, same season same care taken with each guerdon's same season so yes it does work well and the price is great at Sam's

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!
