By hydrogel do you mean the polyacrylic crystals that absorb water and then
release it slowly back to the ground or to any nearby roots? If so, I've
used them extensively in my yard. They are very useful in dry climates
like mine, especially in container plants. I have sandy soil and as I've
incorporated humus into my soil, I find that I use the gel materials less
and less in the ground, but I still use them in my container mixes. You
are best off to hydrate the material before you mix it with potting soil.
It eventually WILL dry out, but it will take longer than the soil to dry
out. You use only a tablespoon or so (dry) in a large pot -- the stuff is
expensive, but it goes really far and lasts many years. I'm sure there are
websites that discuss them. The brand I use is called "Agrisoak," if I
recall correctly. I've also seen "Agrigel."
