Hi, I'm plant sitting for my mother in law and the leaves at the tips are turning brown, Can you tell me why this has happened? Thank you....Kim

Some plants are prone to getting brown tips like spiders, dracaena's, peace lilies and a few others.
Brown tips can be caused by a few reasons, low humidity, poor drainage, using hard-water, over-watering, under-watering, light not right, over-fertilizing, or any combination of these.If you think it's the water, try using rain or distilled.
