With potting soil treated properly with
water-absorbing polymer crystals, you can go on vacation without worry
that your house plants or container gardens will stress out and shrivel
from lack of water.
In fact, when used properly, Water
Crystals will cut in half—and sometimes more—the frequency for watering
house plants and plants in container gardens.
But, don't wait until the last minute before your vacation to treat your
You should apply Water Crystals at
least 3-5 days before leaving and then saturate the growing medium
before departure or you could return to a disappointment. The earlier
application gives the soil, polymers, plant and pot time to adjust to
each other. The plants will find the water stored in the polymer
crystals and drink from them as needed. Hydrated polymers will also keep
the potting soil more moist than soil not treated with them.
In new pottings, Water Crystals should be allowed to expand fully upon
initial watering. You have two ways of doing this: Pre-swelling the
polymer before adding to your potting mix; or adding the crystals in
their dry state into your growth medium.
You can pre-swell by adding water at a rate of at least 12-15 gallons of
water per pound of dry crystals. That's an equivalent to about 4-8
teaspoons for one gallon of water. The polymer will hold much more; but
this rate will get you started. Allow the mixture to stand at least 20
minutes or until water has been absorbed.
The less-messy way to incorporate the crystals to you mix is to add them
dry crystals. To promote the uniform distribution of absorbed water, you
must thoroughly mix or till the polymer crystals into the soil or
After blending with the soil, a subsequent watering should be applied to
maximize water content. Blend at a rate of 5-12 parts soil to one part
gel (by volume). The normal ratio is 8:1, but this can be varied
depending on the soil composition, climatic conditions (temperature and
humidity), and the type of plant to be grown.
To treat existing container plants or container gardens, make holes with
a pencil, dowel rod, screwdriver or other such implement in the planting
medium to approximately 2/3 the depth of the pot. You're goal is to be
sure that the Water Crystals reach the root zone. Add dry crystals
evenly to the holes as follows:

For larger containers, follow the progression
illustrated in the table.
Then, soak, but do not over-saturate, the soil. Remember, it will take 15-30
minutes for mid-gradation crystals to absorb the excess water; less time for
Water Crystals or any polymer crystals are not substitutes for good watering
and fertilizing. They only augment good irrigation and treatment practices.
They increase the medium’s water holding capacity and enhance the efficient
use of available water by the plant. No soil should not be allowed to
completely dry out.
Feeder roots seek out the filled reservoirs of Water Crystals, penetrating
their membranes to provide nourishment to the plant.
