I came on a bag of Lesco Transition Blend fescue seed for 1/2 price because the expiration date was coming up ( April 2010 ) and they know they wouldnt be able to sell this anymore in the fall........ my question is HOW FAR after the expiration date can I use this seed... I was going to put it down on the 1st day of Spring but my plans were ruined due to a pre-emergent my lawn care company put down (they are against spring overseeding ) .. If the germination rate of the Lesco Transition Blend is 90% - with an expiration date of April 2010 - HOW FAR after the expiration date can I use this seed... ? can i still use in the fall ( September 2010 ) ??
