Good to know. Figured this was the case, but you never know.

More heavy rain here tonight--I think the 3 some inches on Sunday night washed off the plants clean 10 times over.

Copper spray tomorrow evening or Thursday evening, depending if we still have the shot at storms tomorrow evening or if the front as passed us by.
