Query: Great for summer heat

We lived in TX when I first tried this. Plants can die in a day outside, so it saved my plants and saved on watering. I just got the 3 pound one for my mom for Mothers day because she keeps complaining about all of the expensive plants she puts out just dry up during the summer even with watering. You put just a little around the root and they swell up and hold water.
