There is not a garden around, that wouldn't benefit from the the addition of polymer moisture crystals. These often undervalued additions to the gardener's arsenal against dryness and compacted soil, have a place in any size garden.

Polymer crystals are safe for edibles, can last up to five years, and although seemingly expensive at the outset, are used in such small amounts that they are really quite invaluable to a container gardener. I really like them a lot for my mother-in-law's special flower containers, so she doesn't have to worry about watering so often.
