Water Crystals must be allowed to expand fully upon initial watering.

Generally, the smaller the crystal, the faster it will absorb water.

  • A midsize crystal is a general purpose product for normal soils, container and potted plants, gardens, crop fields, lawns, trees and shrubs. This size also has been the preferred crystal for hand crafts and neck coolers.

  • For clay soils, use the larger crystals. They will help break up the clay and make the soil more porous. This size is the second choice for hand crafts and home decorations.

  • For sandy soils, bare root planting, and for pre-conditioning a potting soil to retain moisture, use the granular powders.

When pre-swelling is not practical, two heavy waterings should be applied within several hours after dry crystals have been mixed and blended with the soil.

Prior to watering, uniformly blend dry Water Crystals into the medium at a rate of 1.5-2.75 lbs. per cu. yd. Then, after planting, thoroughly water or irrigate the soil to permit full absorption of the Water Crystals. For best results, go back later and soak a second time, if possible.

For best results with indoor plants, pre-swell dry crystals before blending with the growth medium. To do this, add water at a rate of 2 ounces of dry crystals to at least 1.5 gallons of water and allow the mixture to stand 1-2 hours or until water has been absorbed.

Then, to promote uniform distribution of absorbed water, thoroughly mix or till the pre-swelled Water Crystals into the soil or growing medium. After blending with the soil, a subsequent watering should be applied to maximize water content.

Water Crystals are not a substitute for good watering and fertilizing programs. They are a hydrogel or polymer crystal that increases the plant medium’s water holding capacity and enhances the efficient use of available water by the plant. The soil should not be allowed to completely dry out.

With irrigation, it seems to make little difference where within the root system the polymer is located. But for dry land plantings (grass, field crops, etc.), evidence shows that shallow dispersal (1/4" to 1 1/2" deep) to take advantage of any light showers is preferred.

This may not be true in desert-like conditions due to the high evaporation rates, but it does appear correct for dry land areas where light summer showers occur several times a month.

Feeder roots seek out the filled reservoirs of Water Crystals, penetrating their membranes to provide nourishment to the plant.

With potting soil treated properly with Water Crystals, you can go on vacation without worry that your plants will stress and shrivel from lack of water.

In fact, when used properly, Water Crystals will cut the need to water in half; sometimes, depending on the moisture in the air, as much as 75 per cent. That means more convenience, and no worries when you're away and not able to water your plants.
