    1. Sorry for the issues with the gnats. Here is a recommendation directly from the suppliers……..To get rid of existing gnats they recommend drying out the soil and watering less often, to give the soil a chance to dry more, as well as removing any standing water that remains an hour after watering. The company also suggests placing 1/2 inch of sand on top of the soil of all houseplants and leaving it there until the gnats are gone, which the company says could take several weeks. I hope that works. Please let me know how it goes. Thanks

    1. I’ve had great success with it. I’m currently growing some tomato plants that are doing fantastic. I usually mix it with worm castings & the tomatoes do very well. I’ll post some photos of my vegetable & fruit trees when I get a chance

  2. This is the first year i’ve had problems with the potting soil. I have had so many plants die the water is not draining out the of soil well. I’m an avid Gardner and usually have great looking plants but this year not so good. I will no longer use this soil if costco continues to carry the organic.

  3. I bought the Miracle Gro Organic Choice Moisture Control Potting Soil in the 50 quart size at Costco because it contained yucca and coir and was said to prevent over or under watering. I was using other potting soil as well, and potted many plants. The texture is easy to distinguish, and recently I noticed that various plants ( from basil to Angel’s Trumpets) which have normally been vigorous growers, were struggling in their one and two gallon pots with this soil. Although the surface felt dry, using the water meter showed 2/3 of the lower portions of the pot we’re totally wet after 5 days of no water. It appears my basil’s were rotting, even mint, and the very hearty Angel’s Trumpets starts drooping and leaves going limp. I have just started taking the plants I can potentially salvage out and removing as much as I can of of the Miracle Gro soil, replacing the wet heavy soil with my normally used, lighter potting soil. I hope I can save some of the plants. The price was awesome, the soil was not.

    1. Sorry to hear about your experience with the Miracle Grow Potting Soil. Thanks for the comment. It seems to be a common theme among the complaints. I have had a fairly good experience with the potting soil, specifically with my tomato plants. They require a lot of water, so maybe that is why they are thriving. I also drill 2-4 1/2″ holes in the bottom of my pots with weed barrier in the bottom because I like a well drained pot. That may help with the water retention in my case. Maybe Costco will carry a different type next season if there are too many complaints about this type of Miracle Grow. Glad you figured out what the issue was and happy planting!

  4. September here in Wisconsin. I’ve had tomatoes and morning glories in several large planters all summer in this potting soil. This is the FIRT year I’ve been disappointed with Miracle Gro from Costco, which I’ve used for many years. Something was wrong with this formulation, even the morning glories are stunted and hardly flowering at all. That’s like killing quack grass, just unheard of. I picked up bags for a friend who grows lissianthus (sp). They all died except the ones she transplanted in time to save. Very disappointing year on the patio.
