Good for my spring plants

I got 2 of these 2 cu ft bags of moisture control for planting my miniature roses this spring. So for my roses are doing great, they are nice and green, growing and are blooming now. I like this potting soil mixture,helps to keep them not too wet or too dry. Also it has fertilizer in it to help them grow, glad that I got it to use this spring, a good product,was at a good price.

Dependable potting soil. Great price at Sam's

Every year I buy this Miracle Grow Moisture Control potting soil for flowers that I plant in pots outside. The flowers always seem to do well, and I like the idea that the soil is trying to help the flowers survive during the hot summer months when we sometimes have dry stretches. It's also supposed to protect from overwatering, so it is a "win-win." I usually sprinkle in a little Osmicote in the soil when I first plant my flowers. Try to keep an opened bag tightly closed so that the soil is still moist the next time you need it. I'm not sure how effective the drier/dried out soil from an opened bag is.

Easy Water Control

For indoor plants, I find the trickiest part is watering without overwatering. If you haven't tried bottom watering, I highly recommend it. It solved my fungus gnat problem without chemicals. This soil has sponge qualities that also work very nicely, particularly if you are like me and only get to watering one day a week. This soil can easily hold water that long and still drains well enough to avoid root rot.

FUNGAL GNATS in MiracleGro Moisture Control twice!

[This review was collected as part of a promotion.] Two bags of cu ft. sized MiracleGro Moisture Control soil FULL of fungus gnats! Opened up the bag the same day I got them from the store, not shipped, and fungus GNATS flew out! INFESTED 2 cu. ft., disgusted! Contaminated and unusable! That's $17.98 of destruction and infestation to deal with even without putting into pots because they're loose here now. I need not only a refund but damages. Very angry as this is the 2nd time I've bought this brand from the same store and the first had the gnats in egg form apparently, that came out within about a week of using. This time they'd already reached adult stage so I didn't pot with them but have to fumigate all the same, as well as search for new soil to use in new plants needing planting asap. I've read at least 6 other reviews with this problem, and 2 instances myself. I've had enough!

We&#39;re sorry to read about your disappointment with Miracle-Gro Moisture Control Potting Mix and appreciate your feedback.<br /><br />Insects could not survive the composting and packing process. However, it is possible for them to enter the bag during shipping and storage. Insects may also come in with the soil of transplanted plants or enter through cracks, crevices, open windows or doors simply looking for a suitable environment.<br /><br />The small flying insects are likely fungus gnats. These insects do not harm humans and do little plant damage (they primarily feed on the fungus found naturally in soil), but can be a nuisance. A possible way to control fungus gnats includes allowing the soil to dry out as much as possible between watering, which will help control the larvae. Also, you can try applying at least 1/2 inch of horticultural sand on top of the soil of potted/container plants; the larvae cannot burrow through the sand and will die.<br /><br />We want you to be confident in our products. For this reason, we offer a product guarantee to our consumers. At your earliest convenience, please reach out to us at 877-220-3089 if we can further assist.

Trusted By 2 Generations of Landscaping Pros

My mother, who is a 50 year veteran of horticulture science and landscaping, introduced me to miracle gro moisture control. As a landscaping professional myself, I use only this product when creating my pots in the spring. It provides proper moisture and nutrition for my flowers and plants, controlling and keeping moisture in much longer than the other brands and formulas. Well worth the extra cost.

Great Product for Growing Plants

This is my second purchase of Miracle-Gro Moisture Control Potting Mix. I make my own soil for my flowers, vegetables and herbs. I discovered this product while watching a YouTube video about creating successful hanging baskets and knew this was what I needed for my soils. Most people think dirt is dirt, but I have been going to workshops about how to grow healthy plants and make sure that they have all the nutrients that they need. It can be daunting , but this potting mix makes a great base for my plants.

Not satisfied !!!

This item was shipped to me in poor condition. The driver lied and said it was delivered to my front door when it was not. It was left on the sidewalk - 2 sets of steps away from the front door. In addition - the driver included a photograph that was just a black square. The soil was so wet and heavy that 2 people had trouble getting it to the door. The soil is still not dried out so unable to use. I will not purchase this item again from Walmart.
