In anticipation of the dry conditions expected here in Jersey this summer, I potted my herbs and some hanging baskets and used some of that granular moisture retention stuff. Used it according to the pkg. directions, and watered it in. It is sooooo weird! The granules turn into these globs of what looks like clear jello, about 1 inch in diameter, and if you use too much mad: ) it will actually push the soil and plant out of the pot! Ahhh, the marvels of modern science! Think I'll just put a rain barrel out instead!
