HydroSource cross-linked polyacrylamide is a long-lasting,
easy to use, water absorbing soil amendment.
Use in gardens, houseplants, and landscaping to increase
the soil's water holding capacity. You'll be able either to
increase the growth rate of plants, or decrease
the watering frequency dramatically when used as directed.
In undisturbed conditions, it usually lasts 8-10 years or longer in soil.
One pound of HydroSource will absorb up to 48 gallons of rainwater or snowmelt, and 20-35 gallons of tap water, depending on the salt content of the water. HydroSource can be applied wet or dry. Dry granules are easier to use, but care must be taken to water the granules enough to fill them full of water. When hydrated the granules look like chunks of gelatin about 1/2 inch in diameter. Always mix HydroSource evenly through the soil.
Many tests with flowers and other plants have shown that the ideal mix for optimum growth ranges from one part HydroSource to 9 parts soil (10% hydrated polymer) up to 4 parts soil (20% hydrated polymer. This 20% maximum corresponds to approximately 40 pounds per 1000 square feet for each 6 inches of soil depth.) At higher rates growth and flowering may be reduced. Do Not Overdose!!!
Improves Soil Conditions
HydroSource significantly improves available water holding capacity of sandy soil plus increases infiltration rates of water through clay soils by constant hydraulic expansion and contraction of the crystals as they absorb and release water to thirsty plant roots.
Reduces Leaching Losses of Fertilizers/Nutrients
HydroSource absorbs, stores, and releases soluble fertilizers (as well as water) decreasing losses to leaching of both fertilizers and nutrients.
Increased Germination and Improved Early Growth
When HydroSource is placed in the seed row, emergence is increased for most plants, and early growth and survival of seedlings is improved
6" Pots (approx. 2/3 gallon) 1 tsp. dry granules or 2 cups hydrated gel
8" Pots (approx. 1 1/2 gallons) 3 tsp. dry granules or 6 cups hydrated gel
10" Pots (approx. 3 gallons) 4 tsp. dry granules or 8 cups hydrated gel
11" Pots (approx. 5 gallons) 7 tsp. dry granules or 1 gallon hydrated gel
Note: HydroSource should be mixed in the lower half of the pot, because in routine watering, water tends to flow to the bottom of the pot before granules near the top have time to re-hydrate fully. Because the potting soil is generally very porous, it's important, in dry applications, to water slowly and thoroughly to fully hydrate the granules.
Using above rates mix granules or hydrated gel thoroughly in the lower half of the pot. If using dry Granules, fill soil only to within 1 inch of rim of pot, to prevent swelling from pushing soil out of pot.
Depending on container size, use a pencil or 1/2 inch rod (dowel or wooden spoon handle) to poke 4-6 holes around the plant, going to the bottom of the container. Divide the appropriate amount of dry granules evenly among the holes, pushing them to the bottom. Wait at least 2-3 weeks before changing water interval, to give roots a chance to grow into particles.
Rates vary from one pound per 100 square feet for low-water-adapted flowers, to four pounds per 100 square feet for moisture-loving flowers for each 6 inches of soil depth. If you're double-digging for perennials (up to 12 inches deep) you can mix another 1 to 4 pounds per 100 square feet in the lower 6" for superb flower beds.
Use 1 to 4 pounds per 100 square feet, for each 6" of depth.
By hand, or use a whirlybird spreader, broadcast HydroSource evenly over the leveled bed, then turn under with a spade or rototiller. Bedding plants may be given a quick start by mixing a small handful (approx 1/2 cup) of hydrated gel in the backfill 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 (if possible) but no deeper than the rootball or container. The table shows the amount of HydroSource needed to mix in the backfill of round holes 2 1/2 and 5 times the diameter of the rootball/container.
2 1/2 times
For different sized holes mix 2 dry ounces (approx 1/3 cup) per cubic foot of backfill (not including rootball volume). Each ounce gives 1-2 gallons of water storage. After planting, water slowly and thoroughly, preferably in 2 or more waterings several hours apart.
Bareroot stock may be dipped in a slurry of HydroSource fine (1 ounce, 3 scant tablespoons per 1-1/2 to 2 gallons of water, to a honey-like consistancy) to keep the root hairs moist during planting. For survival plantings (such as windbreaks) bareroot-dip the plants and mix a cup to a pint of hydrated gel particles (standard grind) in the backfill of each seedling.
New Sod or Seeded Turf
Rule of Thumb; Watering interval can be extended approximately one day for each 7-1/2 pounds of HydroSouce per 1000 square feet, given evapotranspiration (ET) rates of .25" per day (worst case for Colorado and some other Western States).
For example, 15 pounds of HydroSource normally stores 1/2" of extra water giving two additional days between watering, and 30 pounds stores 1" of extra water giving four additional days between watering.
Warning: To avoid making a lawn "soft", never use more than 5 pounds of HydroSource per tilled inch per 1000 square feet. Thus, 20 pounds must be tilled in 4"; 30 pounds, 6"
Use a whirlybird hand fertilizer spreader or drop spreader to evenly disperse HydroSource over the ground before tilling to appropriate depth. Increase application rate approximately 10% over sloped areas. Save one pound to spread over the top of each 1000 square feet before laying sod or seeding.
Ground may be watered either before or after laying sod, however if it's watered before, you should move around the bare ground using pices of plywood to prevent making deep footprints in the soft soil.
When HydroSource is drilled in with the seed, and watered afterwards, rates as low as 15-45 pounds per acre may be successful. Broadcast rates are much higher. Contact your dealer or WAPI for information.
