Germinating Grass

Grass Seed Germination

Grass seed will germinate at a wide variety of temperatures; the optimum temperatures for germination are in the table below. The temperatures listed are air temperatures which would be almost identical to that in on the surface of the soil barring radiation effects.

Realize though that optimum temperature for seed germination can vary depending on seed age, cultivar, etc. Also, the optimum germination temperature of certain species may not involve a specific temperature but a rhythmic alternation of temperatures. Additionally, the maximum and minimum temperatures for seed germination are poorly defined because of the extreme slowness of germination, especially for the minimums.

Most of our cool season grasses can germinate almost throughout the summer, so there are many other factors control the success of seeding. Poor irrigation, diseases like damping off, and weed pressure are the most common causes of seeding failures.

Upcoming Events

NEMF – Northeast Municipal Foresters

Date: March 18, 2021
Time: 10:00am-12:00pm
Virtual Zoom Meeting
Title: GIS Dashboards & Story Maps
Speakers: Steve Lane & Lindsay Darling

Communication within forestry departments and to the greater public is incredibly important for an efficient forestry program. ESRI, the most commonly used GIS software company for public and private users, has created a suite of online tools that can streamline that process. These tools are often compatible with existing software that forestry departments use. We will demo a few of those products, outline some ways that they could be used by foresters, and give some tips on how to create your own online stories and dashboards. This presentation will not be overly technical and is open to all people interested in how trees and GIS can work together to create valuable public outreach tool.
