When Should I Overseed in the Spring #622169
Asked April 08, 2020, 9:53 AM EDT
When should I overseed my lawn with grass seed this spring? Can grass seed survive if it germinates and we get another snow (forecasted for 4/12)?

For best results overseed in late summer or early fall. Overseeding in spring is not recommended. Preparation to ensure good soil to seed contact is required.
The following bulletin discusses overseeding. It was prepared for Iowa residents but most of what's said there also applies to Minnesota.
University of Minnesota experts do not recommend sowing grass seed in spring before late April or early May. Frost or snow after that is unlikely to prevent germination or damage grass seedlings.
