Grasses used in Colorado are predominantly cool season grasses of which the most dominant is Kentucky Bluegrass.

Kentucky bluegrass is a high quality, sod forming, cool season, shallow-rooted grass with excellent appearance and recuperative potential. It may require frequent irrigation, tends to form thatch and is somewhat disease and insect prone. However, it is extremely cold tolerant and one of the most beautiful grasses there is. It also spreads by rhizomes which helps to repair itself and makes it fairly wear tolerant. Kentucky bluegrass is not the only cool season grass used in Colorado. Fescue and ryegrass are two other commonly used cool season grasses.

Tall fescues are bunching, cool season, deep-rooted grasses that may be more drought resistant. They have few insect or disease problems, are slow to form thatch, and do well in shade. They are slow to recover from divoting, can become clumpy if not carefully established.

Perennial ryegrasses are bunching cool season grasses that are compatible in appearance with bluegrass, do not form thatch, have good heat tolerance and may be drought resistant. They tend to be disease prone and offer poor freezing tolerance if flooded or exposed to wind.

Fine fescues are divided into Chewing fescues, Hard fescues, Red fescues and Sheep fescues. For our purposes they are all grouped together. They are bunching cool season grasses, have a fine leaf texture, offer good shade and cold tolerance, and will adapt to poor soil conditions and fertility. They are not heat tolerant, are susceptible to diseases, can become thatchy, and are difficult to mow.

Buffalograss (warm season grass) is a native grass that can be planted in an area that receives little or no water or care. Buffalo grass is a native variety that does well in this sort of situation. A warm-season grass, it becomes green in mid-to-late May, and becomes dormant again around late September when night temperatures again begin to freeze. Once established, it requires little supplemental water or fertilizer, is low-growing and therefore needs little mowing. It also stands up well to wear. is a sod forming, warm season, native grass that is extremely drought resistant. It is low growing and attractive in appearance with few disease and insect problems. Sound too good to be true? It is. We may be a little too high and have too short of a growing season for buffalograss to thrive. But if you have a warm, south facing location with heavy soil, it is well worth trying. It has the ability to go dormant under drought stress and then to quickly green up and resume growth once moisture becomes available. Native grass seed is expensive; buy only certified and treated seed.

Blue grama (warm season grass) is the dominant native grass that is optimally adapted to our area. It is a bunching, warm season grass with a fine texture. It can be somewhat sod forming if mowed occasionally to a three-inch height. It has excellent heat and drought resistance. Like Buffalograss, it is green only during the warm part of the year and shares the ability to recover quickly from drought stress. It is slow to germinate and establish, so it has limited applications for "quick" lawns. It may well be the grass of choice for a truly water efficient turf area.

USING THE QUICK GRASS SEED CALCULATOR:
Simply select your unit of measurment and enter your area value(s). The total square footage (if appropriate) and seed required to cover your area will be automatically calculated.

USING THE ADVANCED GRASS SEED CALCULATOR:
Enter as many grass areas/lots as you need. If you have lots with areas not needing seed (e.g. buildings, driveways etc.) enter the dimensions of those under 'Voids' to be subtracted from the total area. Clicking the '+' button will add a new area; clicking '-' will remove the associated area.

To calculate the amount of seed you will need for your project, click one of the links below for the type of grass seed you are interested in. A dialog window will appear listing your selected coverage and providing options for calculating your seed.

If you already know the square feet, length/width or acreage of your yard or lot, you can use the 'Quick Calculator'. If you need to add multiple lots and/or subtract areas that will not require seed, you may use the 'Advanced Calculator.'

The dialog window can be moved by clicking and dragging the top 'title bar'. You may click different types of seed to recalculate without re-entering your data.
