Name: greene Savannah, GA (Sunset 28) (Zone 8b) I have no use for internet bullies!
I agree with rainwater being the best when it is available. Container-grown plants rely on the rainfall and whatever water the gardener provides. If a person has a water softener their water could/might contain more sodium than the plants would like over the long term.
