Overview
Watering is the most critical variable for a plant. More than deficiency, it’s excess that kills: most houseplants die from root rot.
How to
Check the substrate with a finger or a moisture meter. Water only when the top layer is dry.
Water thoroughly until it drains, then empty the saucer.
Common mistakes
Watering on a fixed schedule instead of on demand.
Letting water sit in the saucer.
