I have just read here that my long-suffering plant not only is quite probably infested by mites (brown spots) - but also may be overwhelmed by too much fluoride, etc in the water (brown leaf ends). We did have a very late and wet spring here in BC, which might have prolonged the water treatment that is usually a bit stronger in spring, so that the brown leaf ends were inevitable. The water quality is better now but should I try repotting in fresh unsaturated soil? Where the mites are concerned, will the usual diluted Sunlight dish soap be helpful? This seems to be a rather sensitive plant and could that leave a coating of soap residue that my little Sister would react to? It really is a gorgeous plant when it wants to be, though. Your collective thoughts on this??
