Million Dollar Rain

A “million dollar rain” is a rain that helps crops (and makes farmers rich, although not necessarily by a million dollars). This rain occurs in late spring or in the summer, when the crops are growing. For travelers, however, a “million dollar rain” is a misnomer.
 
“A million dollar rain this week and last” was cited in a Michigan newspaper in 1882.

“It’s an expression I used to hear growing up. Million-dollar rain. It means a good rain coming at a good time, not so close to planting as to wash away seeds, not too hard or too long, it’ll get right down into the groundwater and keep the roots happy until harvest time.” Langston said.

Million Dollar Rain
Posted on August 5, 2013 by farm2011
When you get a rain in July or August, a lot of farmers say that it’s a ‘million dollar rain’. With the extremely wet spring that we’ve had, we also haven’t had much rain after the crops started to grow, so lately we’ve been begging for it to rain.
