Use marble-sized polymers to hydrate your plants. I buy the 8.5 oz. container of Decorative Accents absorbent polymers from the Dollar Tree to put in my outside flower beds. I use the handle (dowel) part of a wooden spoon to poke holes into the soil. You then drop the hydrated polymers into the holes and cover with dirt. These great little beads keep the roots happy until the next watering.
