Soil Moist - Hydrogel
I am wondering if any of you have used a product like Soil Moist or Hydrogel. It is a polymer that absorbs a large volume of water. You mix it in with the soil around a plant.
I've not tried them, but was thinking that they would work well for Hosta.
If you have used them, how do they work compared to just working some peat into your soil?
