This can be prevented by watering with rain or distilled water. Brown leaf tips can also be caused by under fertilizing or low humidity. You can remove the brown tips by trimming them off with scissors, following the shape of the leaf tip. One of the features that makes this plant appealing is its ability to produce sets of flowers several times a year, uninhibited by the seasonal constraints that affect most plants. They come in many leaf shapes and flower colours and even dwarf varieties are available.
African violets prefer bright light, but avoid direct sun.
They should be placed away from a window, but not in the dark. They will thrive under artificial, fluorescent lights, making them ideal for dorm rooms lit by fluorescent tubing. They do best at temperatures between 60 and 70 F. Avoid cold draughts. Water with tepid water. The best way to water African violets is by placing the pot in a bowl of shallow water instead of pouring water over the top of the soil.
