Seeding a Lawn - Boulder or Fort Collins Area


A top seeding package by Organo-Lawn is designed to help a thinning or older lawn become lush and thick again.

Our top-seeding package is a four-step process for reseeding the lawn.

  1. We start with a thicker than normal lawn aeration. Core aeration alleviates soil compaction, opens up holes in the ground, and brings dirt to the lawn’s surface.
  2. Step two in the top seeding package is an application of the organic soil conditioner called Humate which is a great grass care product, which has been scientifically proven to increase grass seed germination by as much as 25% and foster new seedling growth.
  3. The third step in the lawn seeding package is an application of our water retention polymer called Rain Maker, which helps sustain a proper amount of moisture in the soil for a successful grass seed germination.
  4. Finally, we apply the grass seed to the lawn. We have three main options of either our Supreme Lawn Mix, low maintenance Ecological Turf Mix, or our Emerald III Turf-type Tall Fescue blend. The professional lawn grass care technician will apply the seed at a full 6 pounds per 1000 square feet in bare areas, a 2-5 pounds per 1000 square feet rate in thin areas, and a 1 pound per 1000 square feet rate in strong areas of the lawn. With proper lawn watering the grass seeds will germinate the lawn will become thick and lush.

Please note that proper lawn watering is required for 3-8 weeks for successfully grass seed germination.

Top Seeding Package Explained:

  • Step 1: Core aeration to alleviate soil compaction and loosen up the soil for the grass seeds to establish.
  • Step 2: Humate soil conditioner is applied to the lawn because it is scientifically proven to increase grass seed germination by 25%.
  • Step 3: Rain Maker our water retention polymer is applied to assist in the lawn watering needs.
  • Step 4: The grass seed is applied to the lawn between 1-8 pounds per 1000 square foot. 1 -2 pounds/1000 sq ft is applied in thick and lush areas, 3-6 pounds/1000 sq ft is applied in average areas, and 6-8 pounds/1000 square feet is applied in bare or dirt areas. You can choose your grass seed type of either our award winning Emerald III Turf Type Tall Fescue, Supreme bluegrass mix or our Ecological Seed Blend.
  • Step 5: The lawn needs to be watered properly. This is very important and we suggest scheduling a sprinkler audit to ensure that the lawn watering is done properly.
  • Step 6: The lawn will need 6-10 weeks to fully establish. A top seeding takes time.

Grass Care Boulder - Grass Care Fort Collins

This is a Boulder area lawn that used to be patchy and thin. After correcting the lawn watering practices, we performed an Emerald III Turf Type Tall Fescue top-seeding package and the customer began using the Ultimate Program. Now this Boulder lawn is now thick and lush.

The top seeding package is designed to get grass clumps growing in the lawn. Then when there is grass care -proper fertilization and proper lawn watering these grass clumps can spread out using rhizomes or underground roots to fill in the gap.


FAQ - Top Seeding

When to a seed lawn in Colorado?

  • In Colorado the highest germination percentage occurs between August 10th- September 1st. This is because the soil temperatures are ideal for seed germination and the nighttime temperatures are gradually getting cooler. If you would like to seed in spring, April 7th – May 31st is the ideal time for germination.

When to seed lawn after applying weed killer?

  • Typically, after a pre-emergent weed control is applied you should wait 4-6 weeks. You might be able to seed after a post-emergent weed killer has been applied depending on the type of weed killer was applied. With our post emergent weed killers we typically recommend waiting 24 -48 hours after a post-emergent weed control is applied before reseeding the lawn but we can reseed a lawn immediately after an application of weed killer. We also recommend waiting 4 weeks before applying a post-emergent weed control or fast release nitrogen lawn fertilizer after seed has been applied.
