It’s All About Germination Time

Germination time is the amount of time it takes a plant to grow from a seed. The germination times can differ from one type of seed to another. In general:

  • Bentgrass – This grass type usually takes between 10 and 14 days to germinate.
  • Bermuda grass – This type of grass takes between 10 and 30 days.
  • Buffalo grass – This grass can take between 14 and 30 days.
  • Centipede grass – This grass takes between 14 and 21 days.
  • Fescue – This type will germinate between day 7 and 14.
  • Kentucky bluegrass – Look for sprouts between 14 and 30 days.
  • Rough bluegrass – This type will see growth between 7 and 10 days.
  • Ryegrass – Look for growth between 5 and 10 days.

It’s important to note that not all the seeds will sprout at the exact same time. But, if you’ve been waiting a sufficient amount of time and the area you seeded isn’t showing signs of life, then you may have to take a look at the factors that may have caused germination to fail before you try again.

The Biggest Contributors to Germination

The most important factors in grass germination are soil temperature and water. Proper soil temperature can be tricky because, in order to know what soil temperature your grass will need, you first have to know if you have a warm season grass or a cool season variety. Warm season grasses will do best in areas of the country that are consistently warm, such as Southwestern and Southern states. Cool season grasses will do best in Midwest, Northern, and Pacific Northwest states.

Cool season grasses will grow best at temperatures between 60 and 75 degrees Fahrenheit and include the varieties:

  • Bentgrass
  • Bluegrass
  • Fescue
  • Ryegrass

Warm season grasses will be happiest between 80 and 95 degrees Fahrenheit and are usually slower to germinate. They include the varieties:

  • Bermuda
  • Centipede
  • Zoysia
  • Buffalo
  • Bahiagrass

When it comes to watering your newly seeded lawn, you need to find just the right amount of water to apply. That’s because too little water will cause the seeds to dry out, but too much water will rot them. Both scenarios will inhibit germination. To make sure you’re watering just enough, you need to ensure there’s enough water to keep just the top two inches of soil wet. Water the area a day or two before spreading seed. If you ever notice water pooling or a ground that is spongy feeling, then you’re probably watering too much.

Growing grass isn’t that difficult, you simply need to know what kind of grass you should grow and when to look for signs of life. Follow these tips and you’ll have a lawn full of green grass in no time!
