Ohio is located in zone 6a on the Plant Hardiness Map provided by the United States Department of Agriculture (USDA). This map enables gardeners to determine what plants (trees, shrubs, grasses, annuals, perennials) will grow in their specific area. Plants are labeled with the specific zones in which they will thrive.
"Cool Season" grasses grow best in Central Ohio. Cool season grasses actively grow in spring and fall when the soil temperature is between 32 and 65 degrees Fahrenheit and include ryegrass, tall fescue, orchardgrass, timothy, and bluegrass.
Today we will talk about Kentucky Bluegrass, one of the most common grasses used in Central Ohio.
Kentucky Bluegrass usually requires about 1" of average rainfall every week during the growing season. Th growing season in Central Ohio is typically April thru October, although this year has been an exception! While the grass will survive without receiving the ideal amount of water, it will begin to go dormant. Dormancy is a natural protective mechanism used by the plant. During dormancy, the grass will start to turn brown. This is usually not a problem, unless the lack of rain exceeds three weeks in length. Then we recommend irrigating to provide at least a minimum amount of water to protect the grass.
Kentucky Bluegrass tends to "green-up" a little later in the spring than other grasses and is frequently mixed with perennial ryegrass to create a lawn that will be attractive throughout the entire growing season.
More to come on perennial rye grass in an upcoming blog.
