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

Conclusion

The hypothesis holds true: the Kentucky bluegrass grows best in slightly acidic soil.

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.
 

Also consider

Use other types of grass such Bermuda grass and carpet grass.

Add clay or sand to the soil. Compare the results with your results from this science project.
