I've recently purchased a ponytail plant. It was doing beautifully, but now the tips of the leaves are turning brown. What causes this.
I don't know the Ponytail plant but some plants, such as the spider plant, have that reaction to chlorine and fluoride in water. If you're watering with water straight from the tap, then consider letting water site for a day before giving it to the plant so that these impurities can evaporate out.
