The relationship between the pH level of soil and plant growthFeatured science projectScience project video

Kentucky bluegrass is a common type of cool season grass. It is normally found in North America. It has bluish--green boat shaped leaves. It grows well in cool climates with sufficient moisture. The Kentucky bluegrass grass can grow to between 1.5 and 2.5 feet.
