Sooner Plant Farm includes the amazing Hydr-Gels to most plants we ship. These little gels expand 700 times their normal size. We add them to the top of each plant we ship to help the soil remain moist during shipping, and by letting them fall into the planting hole, they provide captured moisture, which the new plant can access while getting established. Note; We have discovered some hot and dry loving varieties like lavender's, sedums, yarrows, etc. prefer to not have the Hydro-gels applied.
