To ensure optimal results, it is important that you take extra care of your newly hydroseeded lawn.  Here are some important hydroseed care instructions to follow.

Watering Instructions: 

  • After the lawn is first hydroseeded, allow the mulch to dry before watering. (Usually dry by the next day.) 

  • Hydroseed should be watered 3 times per day for approximately 10-20 minutes per watering cycle.  When the daytime temperature exceeds 85 degrees with high humidity, do not water until temperature drops below 85 degrees. During extreme heat conditions, you can cook the grass and invite fungus by watering.

  • The ideal times are 4:00AM, 11:00AM, and 4:00PM. (Do not water after dark)

  • The hydroseed needs to remain moist in order to germinate properly. The soil does not need to be constantly sopping wet.

  • DO NOT create pools of water on your lawn; just keep the seed consistently damp & moist.

  • After 4-6 weeks you may begin to scale back the watering at your discretion.

Mowing Instructions:

  • Mow grass as soon as needed. Allow area to dry out before mowing. Cut the grass on a high setting to keep the grass cooler and weed seeds from germinating. Try not to mow off more than 1/3 of the plant when mowing. It may be necessary to mow twice a week in the beginning. Repeated mowing will promote root growth and kill some weeds. You do not have to pick up the clippings unless the grass cuttings are smothering the new grass.

  • DO NOT allow the lawn to grow to an unreasonable height. Doing this and then mowing it back down to a normal height will damage the grass, and it will be difficult to bring it back to good condition.

Fertilizing Instructions:

  • 2 weeks after we hydroseed your lawn, it is highly recommended that you apply an 18-24-12 starter fertilizer to the lawn. 

  • 3 weeks after that application you can follow up with an additional starter fertilizer application.

  • Do not apply any weed control to the lawn for the first 10-12 weeks. You may get some weeds in your lawn; they can be taken care of with a weed control fertilizer once the lawn begins to mature.


Key Notes:


  • Some areas will come in much better than others in the first few weeks, this normal due to differing amounts of sun, shade, and water. After 4-5 weeks as the lawn begins to fill in it is recommended that you scratch up the thin areas and seed those areas by hand. Use a mix of fescue, rye, and Kentucky blue grass for the best match.

  • It is important to remember that the hydroseeding application is promoting a perfect seed germination environment. This includes any weed seeds that already exist in the soil. Some weeds are to be expected as your lawn develops. The natural process of the lawn growth will eventually choke out any weeds that develop. Most weeds are annuals meaning that they do not return after they die out. However, you may choose to manually remove them as the lawn develops or to use a herbicide after the lawn has been mowed three times.

  • With proper watering and fertilizing, you will see germination start within 10-14 days, a mowable lawn in about 6-8 weeks, and a fully established lawn in about 6-9 months. Green dye will fade within 2-7 days.

  • Keep as much traffic as possible off the newly seeded areas for the first 6 weeks.

Potential problems must be brought to our attention within 60 days of application.

Preparing your seedbed is an often-neglected portion of the project. Established weeds on the site should be removed. This can be done by manual means or with an herbicide. If an herbicide is used, keep in mind that seeding can generally take place after five (5) days depending on the type used. Dead weeds and grasses should also be removed in the preparation process. Take the time to grade your lawn area. Any irregularities in the grade will still be present when the turf is established. If the soil is very compacted, it should be tilled before raking. Keep the soil approximately one inch below the level of sidewalks, driveways, and edging. Sprinkler heads should be approximately ½ inch above the finished grade. Wetting the soil lightly will aid the preparation process. Moist loose soil will help promote a more even application.
