Will chlorinated water splashing from a fountain damage hosta foliage?
It depends on the strength of the chlorine. People drink tap
water with clorine in it and we use this water to water our lawns
and plants. If you have too much chlorine in the fountain water
then yes, it will harm the hosta foliage. I have a huge hosta
outside my back door and it's 10 feet wide by 4 feet high and I
have no idea why it's so big. It's beautiful though. I NEVER use
cold water on most of my plants, but tepid water right out of the
tap. Of course I can't do the rockery garden this way and will have
to use the sprinkler on the vast majority of my plants. I only use
the other method on planted pots, the flowers by the walkway and
our rose garden.
