Kentucky Bluegrass

Kentucky BluegrassKentucky Bluegrass is a cool season grass and goes by the scientific name – Poa Praternis.  It is easy to grow in locations where it has adapted, with high resistance to diseases such as leaf spot, strip smut and summer patch. The seed is relatively inexpensive and can be found at most home stores in areas where it is commonly grown. It can suffer from summer heat, if not watered and if mowed too often. The stronger types of Kentucky Bluegrass usually requires higher maintenance such as more fertilizer, de-thatching and watering if cut short.

Kentucky Bluegrass – Shade Tolerance

Shade tolerance varies depending on the type of bluegrass. Some will have a higher tolerance to shade. The typically need quite a bit of water and will recover from drought like conditions. Some of the newer types of Kentucky Bluegrass are in fact drought sensitive.

The amount of fertilizer needed depends on the soil types. Typically you should apply between .4 to .8 pounds of nitrogen fertilizer per 1000 square feet. The grass wears relatively well, however like all grasses, heavy traffic will be detrimental to the grass. Kentucky Bluegrass should be mowed when it is 1 and half inches to 3 inches in height. Aim for 3 inches during dry periods to reduce moisture loss. It is best adapted to the north-eastern states, Canada, and  the mountains.

Like all grasses, if mowed too short, excessive moisture loss can occur causing the grass and roots to stress. The grass can recover from drought like conditions. However you are better to allow the grass to grow longer, provide more shade for the roots and to reduce the overall moisture loss. With the long wide blades of Kentucky Bluegrass, it will do well with watering  weekly in dry conditions.
