Miracle-Gro Water Storing Crystals are a 12 oz. soil amendment that absorbs and slowly releases water to prevent over- and underwatering.

Easy to use with a one-time soil mix and activation watering, they are highly rated and trusted by gardeners for reliable moisture retention.

## Description

Give your plants a helping hand and reduce your watering chores with Miracle-Gro Water Storing Crystals. This plant care solution is designed to help prevent both over- and underwatering. The water storing crystals act like tiny reservoirs in your soil, absorbing water and then releasing it slowly to your plants as they need it. This helps reduce water stress on your plants and provides protection during hot weather and periods of drought. These soil moisture crystals are ideal for all of your indoor and outdoor plants, including potted containers, hanging baskets, houseplants, and in-ground vegetable or flower beds. Application is simple: just mix the crystals thoroughly into your potting soil when planting new plants, or incorporate them into the soil of existing plants using label rates (do not exceed the recommended amount). For the best results, be sure to water your plants thoroughly two times, a few hours apart, after applying the crystals to fully charge them. This helps ensure your plants have the moisture they need to thrive. Help your plants thrive with Miracle Gro Watering Storing Crystals.

## Questions & Answers

**Q: Is it safe to use with insects?**
A: I am an industrial chemist (retired) and worked at a complex with a plant making 350,000 pounds of acrylamide (monomer) a day.  While acrylamide itself is quite toxic and carcinogenic. polyacrylamide is utterly harmless.  Polyacrylamide is, as the name suggests, a polymer of acrylamide.  The polymerization reaction destroys the toxicity and carcinogenicity of the molecule.  As long as all of the monomer is removed, there are no worries.  If you are a bit OCD, you can put the "crystals" in a large excess of water, let it sit for a few hours, and pour off the water.

**Q: can it be used in outdoor pots that already have plants in them**
A: Yes, you can use this in pots with plants in them.  Make several holes in the soil (with a stick or pencil) evenly spaced around the plant (avoiding the root area) and incorporate Miracle-Gro Water Storing Crystals evenly into the holes. Cover the holes with soil and water thoroughly to activate the water storing properties.

**Q: I want to add this product to all my landscaping during our CA drought.  Can I sprinkle it over all my plants or do I have to dig up my entire garden?**
A: No you can't sprinkle it on the ground.  But you don't have to dig up your garden either.  What you can do is dig some holes or area around each plant, getting as close as you can without damaging the plant roots.  I usually do this for an established garden areas.  I make the holes (3 for each plant) or digging areas close to plants as I can then put about 1/4 to 1/2 tsp. Then replace the dirt. After I've finished I water a bit to soak the dirt back into place.If you want to see what the Crystals look like when wet. Put about 1/4 tsp in a 2c measuring cup add about 1/2 of water.  They get huge!  Then you can just put this in the ground or planter with a plant.Hope this helps

**Q: Does anyone know how long this stuff lasts in the soil? One season, 5 seasons?**
A: According to literature it gradually deteriorates over a 2 to 3 year period turning into a harmless soil additive with a few nutrients.
