brown tips on Calathea Network
Quick answer
If your Calathea Network has brown tips, the most likely cause is: Calathea network foliage develops brown, crispy leaf edges and tips when the air around it is too dry or when it is given tap water containing fluoride, both of which overwhelm its rainforest-understory humidity needs and its sensitivity to dissolved chemicals in irrigation water.
Start here:
- 1. Switch to distilled, filtered, or rainwater for all watering, since fluoride and chlorine in tap water cause browning leaf edges in calatheas.
- 2. Boost humidity around the plant by grouping it with other tropical houseplants, adding a pebble tray filled with water beneath the pot, or running a small humidifier nearby.
