Wholesale Grass Seed Supplier in Colorado

The right seed mix depends on your space, your goals, and how the area will be used. If you're planting a yard that gets both sun and shade, MasterGreen Sun & Shade Carefree Seed Mixis a great all-around option.

For larger areas like grazing fields or farmland, ForageMax PastureMax delivers dependable forage and coverage. We also offer custom seed mixes for more specific needs like steep slopes, limited water access, or high-traffic zones.

Every site is different, so we’re here to help you choose a mix that supports long-term success and suits the region you’re planting in.

Choosing the right category depends on your land, your goal, and how much time you want to spend on upkeep. We’re here to help you make the best pick for your project.

• Native grasses are species that naturally grow in Colorado and are great for low-maintenance lawns, open land, and areas where you want to promote native habitat. A good example is our Rivendell Pitkin County Seed Mix, which is ideal for the mountain region.
• Specialty seed blends are curated for specific conditions like full shade, foot traffic, or high elevation. Chantilly Creeping Red Fescue is one example that handles cooler, shaded spots really well.
• Custom seed mixes are blended based on your property’s exact conditions—sunlight, soil, use, and location. These are great if you’re working with a unique site or want to match a specific visual or practical goal.

Yes, bulk grass seed is a reliable option for both cover crops and erosion control, especially in large areas or rough terrain. These seed mixes are selected for fast establishment and dense root systems, which help hold soil in place and protect against runoff. They're commonly used on slopes, roadways, and exposed ground after construction or clearing.

Options like Kodiak Annual Ryegrass and Buffalo Brand Low Grow Reclamation Mix are specifically made for these purposes and work well in Colorado’s dry conditions. You can also check our hydroseeding blends for larger-scale applications that require even coverage.

Planting time depends on the type of seed. For cool-season grasses, fall is ideal, specifically September through October when the soil is still warm, and the cooler air helps the grass establish.

For warm-season grasses, aim for late spring after the ground has warmed up. Colorado’s climate can be unpredictable, so planning your timing around the seed type matters. Our guide on when to plant grass seed in Colorado gives more detail on how to match your planting to the season and get the best results.

Yes, preparing the soil ahead of time makes a big difference in how well your grass seed grows. Loosen the top layer so seeds can settle in and make contact with the soil, then rake gently to even it out. You don’t always need to add topsoil, but a thin layer helps if the area is patchy, compacted, or low in nutrients. 

For the best results, start prepping at least a couple of weeks before planting, especially during spring or fall, when conditions are right for seed to take root. Even outside of planting season, you can apply fertilizer and soil amendments to improve soil health and get your site ready for the next round.

For lawns, most cool-season grass seed blends require 1 to 2 pounds per 1,000 square feet. A 50-pound bag typically covers up to 10,000 square feet, which works for large yards or overseeding. For pasture seed or native grasses, plan for 50 to 100 pounds per acre, depending on the species and soil conditions. It’s always smart to check the label for specific seeding rates. If your site has special needs or you want to optimize coverage, we can help with custom seed mixes built for your land and planting goals.

In shady spots or higher elevations, you’ll need seed that grows well with limited sunlight and cooler soil. For areas with low light, shade-tolerant grass seed is best. If you’re planting in a mountain region or cooler climate, look for a mix that’s been proven to handle those conditions. Our Ark Valley Premium Shade Seed Mix works well under tree cover or beside structures, and Mountain Pasture Seed Mix is a strong pick for higher elevations.

To give your grass seed the best chance at life, make sure it stays in place and doesn’t dry out too fast. After planting, lightly rake the seed into the soil, then cover it with a thin layer of straw or mulch to hold moisture and protect it from wind and rain. For bigger areas or uneven ground, products like Hydro Straw help keep seed secure and support healthy germination. This is especially useful when planting around trees, shrubs, or slopes where soil can shift easily.

Many of our customers rely on this extra step to make sure their seed takes root and fills in evenly. You can also explore options covered in our blog on the best mulch for weed control, which includes tips that also help preserve moisture.
