The most common turfgrass in the Spokane area is Kentucky bluegrass. In shady areas, a mixture of Kentucky bluegrass and fine fescue works well. If you are looking for drought-tolerant grass, use a mixture of fine fescues.
The ideal time to plant lawn seed in Spokane is either spring or fall while the weather is still cool. This timing allows the grass to become established before the weather heats up.
When planting the lawn, keep it 4 feet away from trees. This distance allows for less competition for water and nutrients and leaves room to mulch around the base of the tree.
