Hydroseeding is a mixture of grass seed, paper mulch, fertilizer, and water. The grass seed used on your lawn is 100% Premium Kentucky Bluegrass. It is a mixture of Kentucky Bluegrasses which has been formulated specifically for our soil types and seasonal growing conditions. The grass seed will begin to germinate within 5-7 days during the warmest summer months and between 7-14 days during the cooler months. You should see fairly strong growth within 3-6 weeks. Growth may be faster or slower depending on weather conditions. Avoid walking on the hydroseeding as much as possible.

Heavy traffic can permanently damage your new lawn. The bright green color of the mulch will disappear shortly and any dye that has been splattered on brick or concrete can easily be washed off. Grass seed will germinate as a single sprout and then begin to leaf out. When the grass achieves a 5-leaf stage it will then be mature enough to begin weed control and fertilizing. A very lush and established lawn can be achieved in 90-120 days if you are actively caring for your new lawn.


Water is essential to the development of a strong root system in your new lawn. Depending upon the temperature and the time of year you should water your hydroseeded lawn 3-4 times a day and in short amounts of time. I prefer to water at 9am, 12pm, 3pm, and 6pm. You may adjust this schedule according to temperature and your own preference. Each watering should only be approximately 5-10 minutes long. This may vary depending on the nozzle size in your sprinklers, soil type, and weather conditions. Sandy soils will require more water than silt or clay soils. The rule of thumb is that the hydroseeded area should be damp all of the time with a minimal amount of puddles.

The first few weeks of watering are the most critical. As your grass becomes more mature it will require a different watering schedule. Begin to water less frequently with a deeper irrigation and a longer interval between watering. Within 3-6 weeks move to a longer watering time twice a day. After a few more weeks move to once a day with a longer watering time. As your lawn begins to reach full maturity it should be watered once every 2-3 days depending on your own preference.


Do not mow your new lawn until the grass is well established. Wait until the grass is 3-4 inches in height. It is important to keep your mower blades sharp. Dull blades will fray the tips of the grass blades giving your grass a brown appearance. As a general rule of thumb you should only mow 1/3 of the grass blade at a time. So, if your grass is 3 inches tall, never take more than 1 inch off the top. If weeds are beginning too rapidly while your grass is still too immature for chemical application then it may be necessary to mow down the weeds to prevent them from choking out the new grass seedlings.

Avoid sharp turns with your lawn mower and shut off the water for a few days before mowing to prevent damage to the ground.


Your hydroseeding has been applied with a starter fertilizer to help your new lawn grow quickly. The fertilizer used was a 16-16-16 which is nitrogen, phosphorous, and potassium. We recommend that you use a blend such as this until your lawn is very well established. Phosphorous is very important to the root growth of newly seeded lawns so avoid putting on too much nitrogen at first. Usually you can fertilize after 4-6 weeks or after the first mowing. After your lawn is well established you can fertilizer with a nitrogen rich fertilizer such as 25-10-10 to help your lawn grow fast and continue to fill in. It may also be beneficial to apply a fertilizer that contains other micronutrients such as Iron(Fe), Zinc(Zn), or Sulfur(S).

Always follow label instructions when applying fertilizer. It is also important to incorporate fertilizer into the ground as quickly as possible after application. This is done by watering immediately after fertilization. Aerating is also very effective when the grass begins to become well established.

Apply fertilizer during a cooler part of the day and avoid fertilizing on hot and windy days. Nitrogen is very volatile and will begin to escape into the atmosphere as nitrogen gas. This is why it is important to incorporate fertilizer immediately. This way your fertilizer is being used by the plant and not escaping into the air. Nitrogen is also mobile in the soil which means that it can be leached out of the root zone and not taken up by the plant. Avoid leaching by not watering too excessively.

Weed Control

Most likely some weeds will still germinate and grow faster than new grass. It is important to get a good control of the weeds before hydroseeding takes place. Any foreign grasses can be very difficult to remove after your new lawn begins to grow. Broadleaf weeds are much more easily controlled. When applying weed control to your lawn always follow all label instructions including application rates and practices. Using a chemical improperly can result in weeds building a resistance to the chemical or even damage your new turf. When grass is immature avoid a strong mixture of chemical. Mix chemical at the lower end of the approved application rate and always follow mixing instructions. I have found that liquid forms of weed control are more effective than granular forms.

Touch Up

If these care instructions are followed properly you will be very pleased with your new lawn. Remember that grass takes a long time to become an established, lush lawn. It may take a year or even longer for problematic areas of your lawn to fill in. These areas may include puddles, dry spots, heavily shaded, or heavy traffic areas. We offer one free touch up to any areas which did not grow if the customer followed all care instructions.


Thank you for your business. We look forward to working with you in the future. Enjoy your new lawn!
