Why these dates

Cucumbers germinate quickly in warm soil (70F+) but get destroyed by cucumber beetles - row covers until flowering are essential in much of the US.

The dates above are anchored to Minnesota's average last spring frost date of 05-15, with offsets standard across university Extension publications. For zone-specific local timing, use the frost date lookup tool with your ZIP code.
