S208--Lawn Maintenance Weed and Feed

Question Set 2 1. What type of grass seed should be used and how much per 1000 square feet? Shall use a 70/30 ratio of Bluegrass/Perennial Rye seed and apply 3# per 1000 square feet 2. What type of fertilizer should be used and how much per 1000 square feet? Use 100% slow-release fertilizer and apply 1.5# per 1000 square feet. 3. Per SOW, it states to use Crabgrass preventer in the spring and vibratory aerate and overseed in the fall.  If crabgrass preventer is applied in the spring, you must wait a minimum of 110 days before seeding which brings you into late fall and the seed will not germinate and grow strong FboNotices before winter sets in.  Please advise Do vibratory aerate and overseeding in the spring (May). Omit crabgrass preventer.
