SEEDING OR RESEEDING YOUR LAWN
Top Seeding Packages
A top-seeding package from Organo-Lawn is a four-step process.
Whether you are reseeding your lawn or starting from scratch, our process will help your grass seeds take hold, grow quickly, and stay healthy.
- Step 1 – Core Aeration: 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.
- Step 2 – Humate Soil Conditioner: An application of Humate soil conditioner is applied over the entire lawn. Humate has been scientifically proven to increase grass seed germination by as much as 25% and foster new seedling growth.
- Step 3 – Rain Maker: Our water retention polymer called Rain Maker are polymers that will help sustain a proper amount of moisture in the soil for a successful grass seed germination.
- Step 4 – Grass Seed: Finally, we apply the grass seed to the lawn. We have three options of grass seed types to chose from.
- Emerald III Turf-type Tall Fescue – The ideal grass type for Colorado lawns and is three different types of tall fescue grasses.
- Supreme Lawn Mix – A very high quality seed mix of predominantly bluegrass seeds.
- Ecological Turf Mix – A fine fescue seed mix designed for low maintenance areas.
- You will need to make sure the sprinkler system is set up to be watered properly. This is a very important step, and a sprinkler audit with Organo-Lawn will ensure that the sprinkler system is set up to water for ideal grass seed germination.**
- Patience is required because the lawn will need 6-12 weeks to fully establish. A top seeding takes time and consistent lawn watering.
**Disclaimer: This top-seeding package is guaranteed only if Organo-Lawn performs a sprinkler audit on your system within two weeks of the seeding package.**
Important Note: With proper lawn watering the grass seeds will germinate and the lawn will become thick and lush. Please note that proper lawn watering is required for 3-8 weeks for successful grass seed germination.
Services Included in a Top-Seeding Package:
The first step of the top seeding package is a thorough core aeration.
The second step of a top seeding package is applying humate soil conditioner.
We add rain maker to our top seeding package to help with watering.
The final step is to apply the grass seed to the lawn.

Emerald III Turf-Type Tall Fescue is The Best Grass Type for Colorado
Emerald III Turf-Type Tall Fescue is the best grass type for both shady and sunny lawns
Emerald III Turf-type Tall Fescue grass seed is the ideal grass type for almost all of Colorado’s conditions. Boulder and Fort Collins area lawns thrive when seeded with Emerald III grass seeds. Turf-type tall fescue does extremely well in areas of full sun or full shade. Emerald III will tolerate the high pH soils of Boulder and Fort Collins. Emerald III grass also has very strong rhizomes and will bounce back from heavy foot traffic or heavy use. After the grass seed establishes, the turf will perform well in both hot-dry conditions or cool-moist conditions.
Organo-Lawn believes that this grass seed blend is the best seed type for Colorado’s wild weather and hot and dry summers. Emerald III fescue seed can also tolerate heavy shade areas like underneath deciduous trees. It’s also highly recommended for anyone starting a new lawn, because it will require 33% less watering than bluegrass lawns.
Emerald III Turf-Type Tall Fescue Characteristics
- With proper lawn watering, tall fescue grass seeds take 16 days to germinate from seed.
- Tall fescue is a thicker bladed grass, however, because it is a “Turf-Type tall fescue” it is soft on the feet and does not have the ugly clumpy look that some unimproved tall fescue grasses produce.
- Tall fescue is a very shade tolerant grass and can grow in full sun or up to 80% shade. Compare that to bluegrass which can only tolerate 30% shade.
- Tall fescue roots can grow up to 3 feet deep in ideal conditions and usually about 12” deep in the Colorado soils in and around Boulder or Fort Collins areas.
- Tall fescue has very strong rhizomes (grass roots) and therefore it is an excellent selection for high traffic areas because it can repair damaged areas very quickly. This quality makes this grass type ideal for people with dogs or young children.
- Tall fescue can grow very fast and may require more frequent mowing (once per week) than fine fescue grasses.
- Tall fescue is a clump grass, this means they grow in lots of small clumps. If conditions are good all these clumps appear as a nice full thick area, if conditions are bad (drought) the fescue will reduce to smaller clumps and this will make the area look patchy which is a good indication of drought stress.
- Tall fescue is not drought proof and will die if not watered (i.e. zero water for 1-3 months), but are very drought tolerant and use about 1/3 less water than bluegrass.
- Tall fescue is tolerant to many lawn diseases like Necrotic Ring Spot and Ascochyta/Dollar Spot.

Supreme Lawn Seed (Bluegrass Mix) is a Good Grass Type for Colorado
Supreme grass seed is ideal for sports turf or to match an existing bluegrass lawn.
Supreme Lawn grass seed mix is a blend of selected fine-textured lawn grass seeds that form a dense, uniform sod with outstanding deep dark green color, excellent durability, good heat and drought tolerance, strong winter hardiness, and nice lawn disease resistance. Supreme Lawn Mix incorporates the features of the Allblue bluegrass blend, then adds Creeping Red Fescue which tolerates the poor soil conditions found in Boulder and Fort Collins area lawns.
Supreme lawn grass seed is an extremely high-quality Kentucky blue-grass seed type that is ideal for Colorado lawns and used by grass seeding companies for lawns with adequate sun. It is a fine bladed grass, with deep dark green color, excellent tolerance to foot traffic, fair heat and drought tolerance, good winter hardiness and is disease and fungus resistant.
Bluegrass’ major drawback is its poor ability to establish in heavily shaded areas. Bluegrass needs about 70% sunlight throughout the day to stay healthy in a Boulder or Fort Collins area lawn. If a homeowner has tried numerous times to seed an area of the lawn with little success, chances are there isn’t enough sunlight for the bluegrass sod or grass to sustain in that area. For shady areas, Emerald III grass seed would be the best option for an area that does not receive as much sunlight.
Bluegrass is the most common grass type in Colorado lawns. This is due to the fact that bluegrass is easy to sod and is virtually drought proof. Even though bluegrass requires more water to stay green, if a bluegrass lawn receives zero water, the bluegrass lawns will go dormant. When water becomes available again (even if it is one year later) a bluegrass lawn will come out of dormancy. Bluegrass is virtually drought proof.
Bluegrass Lawn Characteristics
- Bluegrass grass seeds take 23 days to germinate from seed.
- Due to strong rhizomes (roots that grow underground and then produce another blade of grass) bluegrass is very good at filling in bare areas and are more durable to foot traffic. Therefore, bluegrass is a good selection for sports turf, lawns with heavy dog traffic or lawns where children play.
- Bluegrass lawns requires more water to stay green than fescue lawns, but bluegrass lawns will not die if it goes into a severe drought. Bluegrass lawns will go dormant and turn brown quickly if water is reduced. Therefore, bluegrass lawns are drought proof, but fescue lawns are more drought tolerant.
- Bluegrass will not grow very well in full shade. Bluegrass lawns needs 70% sun per day to stay healthy.
- There are over 100 different cultivars of bluegrass. The bluegrass in supreme seed mix is selected for its high tolerance to heat and drought stress and its overall health and color.

Ecological Grass Seed Mix (Fine Fescue) is a Good Grass Type for Non Irrigated Areas
A grass type designed for low maintenance areas!
Ecological Seed Mix is a grass seed mix we recommend for use in non-irrigated and low use turf areas around a house. Ecological seed is a quick establishing, dense, low growing turf that requires less mowing, water, and lawn fertilization than bluegrass or turf type tall fescue grass seed blends. This grass seed mix is very fine textured, can be used in open sun and yet has good shade and drought tolerance. It tolerates poor soil conditions and low soil fertility. This grass mix is not recommended for high traffic areas or athletic fields. This grass seed option is rarely used in residential lawns and is more widely used in areas like septic tank leach fields, berm areas and non-irrigated sections of lawns. We use the this mix as part of our lawn seeding services for low foot traffic lawns. Ecological grass seed mix is a much better grass seed choice for use in Boulder and Fort Collins area lawns compared to buffalo grass which is a warm season grass.
Fine Fescue Grass Characteristics
- Fine fescue takes 16 days to germinate after we have performed our lawn seeding services.
- The blades of the grass are strong, but the rhizomes of fine fescue is not very strong and therefore do not tolerate foot traffic very well.
- After established, fine fescue requires less frequent lawn mowing, less lawn fertilizer and less water to stay healthy compared to bluegrass lawns.
- Fine fescue is not drought proof and will die if left without water for a long period of time (1-3 months with zero water).
- Fescue grass is a clump grass, this means they grow in lots of small clumps. If conditions are good all these clumps appear as a nice full thick area, if conditions are bad (drought) the fescue will reduce to smaller clumps and this will make the area look patchy, which is a good indicator of drought stress.

FAQ – Over Seeding a Lawn
When is the best time of year to seed a 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 7 – May 31 is the best time to seed a lawn in the spring.
When can a lawn be seeded after applying weed killer?
This depends on what type of weed killer was used. It is best to read the label of the weed killer that was applied before seeding a lawn.
Is Kentucky bluegrass shade tolerant?
No, bluegrass needs about 70% sunlight throughout the day to stay healthy. If you have tried multiple times to seed a lawn under a tree with little success it may be that there isn’t enough sunlight for the bluegrass to sustain in that area. A better grass type choice would be turf type tall fescue because it can tolerate up to 80% shade.
Is turf-type tall fescue ugly?
No, turf type tall fescue is a type of tall fescue that is aesthetically pleasing to the eye and soft on the feet compared to unimproved coarse tall fescue. Turf type tall fescues do not have the ugly clumpy look that some unimproved tall fescue grasses produce. Turf type tall fescue is a very shade tolerant grass and can grow in full sun or up to 80% shade. Turf type tall fescues can tolerate heavy foot traffic because they have very aggressive rhizomes and the deep digging roots. Tall fescues require 33% less water to stay healthy and green compared to bluegrass.
Are fine fescue grasses drought proof?
No, fine fescue are drought tolerant because they need about 33% less water to stay green compared to a bluegrass lawn, but fine fescue is not drought proof and will die if left without water for a long period of time (1-3 months with zero water).
What type of grass is the ugly clumping grass that grows in lawns?
Unimproved tall fescue grass is a clump grass, this means they grow in lots of ugly clumps. Unimproved tall fescue is ugly and unsightly and often rough on the feet. Turf-type fescue is aesthetically pleasing and soft on the feet.
