Why are the leaf tips on my diffenbachia brown and brittle?

Browning leaf tips can indicate low humidity or salt build up in the soil, or chemicals in your tapwater. Indoor air can be extremely dry during the winter months. You can try misting the plant to increase humidity. Leaching the soil by flooding it, allowing to drain, then flooding it again can help leach out excess salts. If you use a liquid rather than a granular fertilizer, you will help prevent salt build up in the soil. Another common cause of brown leaf tips is fluoride or chlorine in your tap water. You can either allow tap water to sit out overnight before using it on your diffenbachia, or you can use bottled water for your plant. Good luck with your plant!
