How Long Does It Take for New Grass to Develop?

When you’re planting new grass seed in your yard, it can seem like it’s taking forever to start sprouting.  You may even ask yourself if it’s growing more slowly because you’re watching it!  The truth is that there are a few different factors to consider that will influence just how long it really takes for that new grass to start thriving. 

Grass Seed

Type of Grass Seed

One of the first things to consider is what variety of grass seed you have. Here in Northeast Ohio, most of the grass seed is what’s called cool season grasses, that grow best between 60 and 75 degrees Fahrenheit.

Some of the most common cool season grasses in the Northeast Ohio area include Kentucky Bluegrass, Bentgrass, Ryegrass, and Fescue.

 

Germination

The process of a seed growing into a plant is called germination.  The amount of time it takes for the germination process can vary from one seed type to another.

      Ryegrass: This type usually grows in 5-10 days

      Fescue: This grass germinates in 7-14 days

      Bentgrass: Look for growth between 10-14 days after seeding

      Kentucky Bluegrass: Usually sprouts between 14-30 days

 

Growing Factors

How long the process takes can also be affected by the weather.  Factors such as temperature, soil PH, water, sunlight and yard pests.  Two of the most common factors that slow down growth are cooler than normal temperatures, and overwatering from heavy spring rains.

      Cool season grass grows best between 60-75 degrees Fahrenheit

      A few days before seeding, water the soil and saturate to a depth of 6-8 inches

      Water new grass seed 1-2 times daily unless rainfall is keeping the soil moist
