We got the same weather forecast here, Jen. Rain on and off for a week. I did the same thing last week right before a rain, dumped comet on every rhizome in a bed that is giving me grief. It seemed to work for a bit as I only had 1 more loss yesterday, But it poured starting yesterday afternoon and rained most of the night. The raised beds in our back yard will be flooded again so I will have to wait for low tide to see how they did.
Low tide....
I love gardening, but I hate shoes that squish when you walk due to walking thru 6 inches of standing water.. Sorry we in Missouri send so much rain your way..
Blessings
