RE: Clover question
Innoculant costs I think $3.00.
My only comment is that I would never blend Red & White Clover. The reason, In order to maintain the plot, you will need to mow to encourage clover domination. White clovers are generally mature at 6" and Red at 16" - Red clover - can only be mowed once - maybe twice on good soil over the course of the year. if mowed more often with the blend - White clover easily dominates, and the red clover disappears.
Alsike, is a different clover that works better in a blend than Red Clover when mixed with white. It can be mixed with Red or White - but will peter out in about 2 years.
