    ...water collecting substances that are small until they get exposed to water, then they swell up to about grape size? Usually found in potted plants. They were a fad about 5 years ago, anybody still use them today?

    Have any of you tryed ripping a clean disposaple diaper and mixing with the potting soil? With the cost of diapers it might not be cost affective, but every once in a wile the grand kids mom leaves one here and I'm timpted to try it. They sure hold a lot of water when the GS gets in the wading pool, might just have to try it I guess.

    Polyacrylamide (PAM) is the product, sold under numerous brands and monikers, in different grades and grinds. Some are ground fine to make a slurry for bare root tree dipping while others are used under sod and are course grind.

    Grades range from cheap ones with little water holding ability and degrade quickly to those that will hold up to 400 times their weight in water and last about 7 years when mulched or otherwise shaded.

    I use cross linked polyacrylamides from "Hydrosource", course grind, 400X for holding capacity. http://www.hydrosource.com/serv01.htm
