Q

When is the best time to seed native grasses such as streambank and western wheatgrass into an existing Kentucky Bluegrass lawn? Some of what I've read leads me to believe that it would be best to seed in late fall so the seed will germinate in the spring. But I wonder if it would be better to seed in early fall after stressing the KBG. I will also be seeding sheep fescue, but I've seen conflicting information on whether that is native or introduced. My goal is to have a lawn that can survive with no water, and stay green with very little water.

Answer(s)

A

A good time to do this is from August 15 to September 5.  This allows the grass to germinate and get to the 3-4 leaf stage which is big enough to get through the winter.  The late fall seeding for spring germination works better for  legumes such as alfalfa and clover.  It does not work as well for grass. The next best option is to seed in April.  Sheep fescue is a native of North America.
