I hear you talking about something to help cut down on the watering of my containers, but not sure what it is?
It’s called “Soil Moist” and truly is a life saver for container gardeners. The small polymers (mixed into the potting soil) absorb water and swell up to 20 times or more their original size. When the soil dries out, they release water back into the soil which helps cut down on your watering. I like to mix it into the bottom 3/5 of the potting soil, and then add the rest of the potting soil without it. That keeps it lower into the soil and gets plants to root deeper. Please read the label before using. Note: You can add this to existing planters by taking a pencil, poking it down into the soil, and creating several cores. Then sprinkle in a few Soil Moist crystals, and fill back in.
