Hello, I recently bought two Umbrella plants. Looking at the leaves, I noticed lots of white marks on them. I talked to the store and they said it's because they were watered with city water so it will leave stains. I went through this with a ficus tree and it took me hours to scrub down each leaf in order to remove these. I was wondering if anyone knew of a more efficient way to do this. Also I recently heard that even once I repot the plant in organic soil I should still cover the soil in large rocks so my chameleon won't eat it. Is this true? Thanks in advance for any help.
