Ask The Plant Expert:
I have some spider plants which are brown at the tips of the leaves, I’m using tap water that has been standing open to the air for a few days, and have been trimming these bits off, will this help? – Mathew
Flower Shop Network Plant Expert Reply: Matthew,
This is a problem I have seen first hand in our greenhouse. What you have is most likely fluoride damage. These plants are very sensitive to fluoride. Unlike chlorine, fluoride doesn’t evaporate effectively from an open container. We had trouble in the greenhouse until we started using well-water instead of city water. I recommend catching rain water or use distilled water. Once you switch the browning should stop.
Hope this information was helpful.
