Watering houseplants can be challenging enough when they all need different amounts and at different times. But there's also the matter of what type of water you give your plants and how it plays an important role in their health.
If you've mastered how often to water houseplants, you know that they can be both demanding and dramatic when you get it wrong. Even when you know how much water to give them and when, they can still have negative reactions to watering, turning yellow or even dying completely.
