Please read carefully. Failure to follow the Instructional Care Guide voids the warranty!

Please Note: It is the customer’s responsibility to report any potential challenges with turf establishment within the first 30 days. Otherwise, the warranty of our product is voided. St. Louis Hydroseeding does transfer its supplier’s guarantee on seed germination to its customers, provided this instructional brochure is followed exactly.

Watering

Do a moisture test before setting your automatic sprinklers to see how long it takes to puddle; then decrease this time by approx. 30 seconds. Keep the new lawn moist at all times. Apply short quick waterings throughout the day; approximately 3-6 times per day between 6am and 6pm. When the temperatures are cool, set waterings for 2-3 times a day or less depending on the moisture content of the mulch and seed. Sprinkle it lightly to avoid puddling, run-off, surface erosion, and channeling. Remember also that the set times might have to be decreased as the days go by due to the soil becoming saturated. Do not decrease the number of intervals, but the length of time each interval waters.
You must change your watering technique and adjust it according to the fluctuations in the weather.

DO NOT OVER WATER to the point of standing water.

Diseases & fungicide

Approx. May 15th – Sept. 15th
Pythium or Dampening Out could infect your new lawn. Within 14-17 days after installation spray your new lawn with a fungicide. Call a local professional that does Turf Spraying or stop by a local Nursery/Turf Supply Outlet and pick up the appropriate fungicide and do-it-yourself. (The label must specify that the product is for Pythium.)
It is the owner’s responsibility to see that fungicide is applied by the 17th day. In some cases, additional treatments may be necessary.
Remember, if fungus is not treated, a dampening out of your entire lawn may occur in which all or part of your lawn could die.
St. Louis Hydroseeding is not responsible for any diseases or fungus that might grow in the new lawn.

Slime mold

Slime mold is an algae that grows on top of the soil. The soil discolors to a medium/dark green, or orange color. Algae will negatively affect the germination and growth of your newly seeded lawn. The condition itself is caused by too much water and/or an excessive amount of compost in your soil.

NOTE: If slime mold becomes a problem, allow the affected area to dry slightly, but remember moisture is necessary for continuing germination. (Supplemental hand watering may be advantageous in these areas). Spray the affected area with fungicide. Check with your local Nursery or Turf Supply Store for a product (such as FORE or DIATHANE WF) that would be recommended for slime mold control.

Fertilizing

Your lawn should be fertilized in 20-25 days. Using a good balanced fertilizer such as 15-15-15 or 16-16-16.
Do not use Weed and Feed at this time – wait until the 4th or 5th mowing. Be sure fertilizer is applied evenly and watered in thoroughly to avoid burning the grass.

Weeds

Weed seeds are in the soil and blown in from the wind. A broad leaf weed killer can to be applied after the 4th or 5th mowing. St. Louis Hydroseeding is not responsible for any weeds that come in with the new lawn.

Mow

Mow your new lawn when over 50% of it reaches a height of 3 1/2”. Mow lawn to approximately 3” high. Do not expect your lawn to look like established turf at 30 days. It may be quite sparse. If it looks like a lawn from a distance it should be fine. The grasses will thatch together and thicken up each time you mow. You will have to mow 5-7 times before the lawn will look lush and thick. At least for the first 5-7 times of mowing, use a grass catcher when you mow.
Sharpen Lawn Mower Blades. Thoroughly wash mower prior to mowing new lawn to help reduce any possibility of spreading weed seeds, fungal spores, and other potential diseases. Small bare areas are usually caused from seed drying out or being flooded and washed away. These areas will have to be hand seeded to introduce new seedlings for growth.

Insects

Protect your lawn from insects with commercial insecticides (only if needed). When dealing with insecticides it is best to talk with a professional. Don’t make the mistake of not getting proper information before reacting!
