Use the following suggestions as a starting point...
 |
One pound of Water Jelly Crystals will absorb up to 35 gallons of rainwater or snowmelt, and 20-25 gallons of tap water, depending on the salt content of the water. |
|
|
Water Jelly Crystals can be applied wet or dry. Dry granules are usually easier to use, but soak them thoroughly to fully fill them with water (hydrate). When hydrated, the granules look like chunks of clear gelatin about 1/2 inch in diameter. |
|
|
Dry Application For large quantities of potting soil or backfill around trees and shrubs. - 1.5-2 pounds/ cubic yard of potting soil or backfill - 1 ounce/ cubic foot of soil |
|
|
For small quantities of potting soil - 1/2 tsp per quart of soil. Note: Since dry granules swell to many times their original size when water is added, 15-20% swelling room must be left in each planting hole or flower pot to compensate. |
|
|
Wet Application Best for small applications such as repotting house plants, and planting shrubs, small trees, and bedding plants. 1/2 tsp. of dry granules absorbs approx. 1 cup of water. - 1 ounce of dry granules absorbs approx. 1 1/2 cups of water. - 1 lb. of dry granules absorbs approx 30 gallons of water. Mix granules in water and allow to stand for 60-90 minutes (Hot water works faster) Once you have the polymer all soaked up, the application rate is roughly one part hydrated polymer to four parts soil. |
|
|
House/Office Plants - 6" pot (2/3 gal.) 1 tsp. dry or 2 cups hydrated - 8" pot (1 1/2 gal.) 2 tblsp. dry or 6 cups hydrated - 5 gallon pot 7 tsp dry or 1 gallon hydrated Note: Mix Water Jelly Crystals in lower half of the pot, because the water tends to flow quickly through porous potting soil, before the granules near the top have time to re-hydrate fully. |
|
|
Repotting Using above rates mix granules or hydrated gel (best!) thoroughly in lower half of pot. If using dry granules, fill soil only to within 1 inch of pot rim, to prevent swelling out of pot. |
|
|
Existing Plants Depending on container size, use a pencil or wooden spoon handle to poke 4-6 holes around the plant, going to the bottom, Divide the correct amount of dry granules evenly amount the holes, pushing them to the bottom. Water slowly to hydrate the granules. Wait at least 2-3 weeks before changing watering intervals, to give feeder roots a change to grow into granules. |
|
|
Vegetable and Flower Gardens Use 4-5 pounds/ 100 sq.. feet for low-water adapted flowers, and up to 10 pounds/100 sq. feet for water loving vegetable and flowers. Hint: The addition of weed-barrier fabric will further reduce the need for water or weeding. Application suggestions... By hand, or using a spreader, distribute the granules evenly over the leveled bed, and then turn under. Bedding plants may be given a quick start by mixing a handful of hydrated gel in the back fill of each plant, taking care not to leave clumps of gel. Water bed thoroughly after planting. |

|
Trees and Shrubs Dig a hole 5 times the diameter, but no deeper than the root ball or container. The table shows the amount of dry granules needed to mix in the backfill of round holes 2.5 to 5 times the diameter of the container. Container Size 2.5 times 5 times - 1 gallon 1/3 cup 1/2 cup - 5 gallon 5/8 cup 3 1/2 cups - 15 gallon 1 2/3 cup 7 3/4 cups. If you don't want to dig such a big hole just calculate the amount of backfill and figure one once per cubic foot. The bigger the hole the more polymers you can use and water storage you'll gain. |

New
or Seeded Turf Watering intervals can be extended approximately one day for
each 7 1/2 pounds of Water Jelly Crystals per 1000 sq. feet given
evaporation rates of .25" per day. For example, 15 lbs. of granules normally
stores 1/2" of extra water (two additional days between waterings) and 30
pounds stores 1" of water (four additional days between watering). Warning:
To avoid making a soft law, never use more than 5 pounds of Water Jelly
Crystals per tilled inch per 1000 square feet. Thus, 20 pounds must be
tilled in 4 inches; 30 pounds 6". Increase application rate roughly 10% over sloped areas. Save one pound to spread over the top of each 1000 sq. ft. before laying sod (but not if you are seeding, as it just breaks down in the wet phase if not covered by soil.) Water thoroughly and slowly. Application: By hand, or using a spreader distribute the granules evenly before roto-tilling to appropriate depth. |
Water Jelly Crystals (cross-linked polyacrylamide copolymer gel) are generally considered not to be a health hazard. They're non-toxic, safe for use around pets and young children, and are considered to be environmentally beneficial. Do not taste or eat any of the materials described in these activities. Since these crystals are designed to be used with plants, bury them in a planter box or garden when you're finished using them. Throwing them away is such a waste. In reality, you have a reusable, lifetime supply.
