Fortunately, grass seed for cool weather can be bought in mixtures. This provides the benefit of two or more types. These grasses are similar to each other and compatible in terms of leaf texture and growth.
Kentucky Bluegrass –
- Most widely grown grass seed for cool weather.
- Requires about 20 days to germinate.
- Medium textured, green to dark green lawn of good density.
- Ability to spread into thin areas makes it a good choice for reviving stressed lawns.
- Fair high temperature tolerance and good cold temperature tolerance.
- Often used in low to medium traffic areas.
Tall Fescue –
- Toughest grass seed for cool weather.
- The coarsest texture of any cool season grass, as well as the lowest shoot density.
- Resists insect feeding and has extensive root system that efficiently draws on soil moisture—making it a good candidate if insects and drought are a problem.
- Fair cold temperature tolerance. Good heat tolerance.
- Recuperative potential is quite low because it does not spread laterally.
Fine Fescue –
- Group made up of hard fescue, sheep fescue, creeping red fescue, and chewings fescue.
- Medium to dark green.
- Needle fine texture.
- Good shade tolerance.
Perennial Ryegrass –
- Commonly mixed with Kentucky Bluegrass to improve wear and tear, allowing growing in shade, and speed up establishment.
- Requires about 10 days to germinate.
- Shiny, medium to dark green.
- Fine to medium in texture.
- Does not spread laterally.
- Tolerant of cold and warm temperatures.
- Germinates rapidly, making it useful if you need to get a lawn off to a fast start.
Creeping Bentgrass –
- Used mostly on putting greens, or for lawns used for boccie or croquet.
- Very low, fine textured grass.
- Spreads readily through rhizomes.
- Susceptible to a wide range of fungal diseases. Requires frequent mowing. Considered high maintenance.
- Good cold temperature tolerance. Fair heat tolerance.
