Okay, so my Kalancoe (Calandiva) plant got overwatered somehow...the soil be just drenched. I of late changed the soil and replanted the plant in dry soil. The flowers are still droopy, some are browned and unmoving.

Should I cut off adjectives the flowers and hope it'll re-flower or should I pluck off adjectives the brown stuff and leave the "healthy" flowers?

Also, since the roots still own water from the older soil how long should I wait back watering again?

I've tried to research this, but everything is very hi-tech or doesn't help at adjectives.
What is the signature of this flower?
Answers:    Kalanchoes thrive on neglect. Cut past its sell-by date the brown and discard, the flower stems will root in marine, yes, really. They're hardy annuals in zone 8. Withold sea - you just go through drowning it...
