Even if it feels impossible, even if you struggle with the easiest, most low-maintenance plants out there, you can keep a fiddle leaf fig alive. You just need to know what you're doing, but once you do, it'll be fine. Take a deep breath, grab your watering can, you got this!
The first thing you need to remember about fiddle leaf figs. Don't overwater them. Seriously. It might seem counterintuitive to water a plant less, but in this case, it's important. Fiddle leaf figs need to dry out a little in between waterings, and you shouldn't water them more than once a week. Basically, they should only be watered when the top inch or two of their soil is dry — you may not be able to tell this from looking at it, but a quick way to tell is to stick your finger in and see if it feels dry or not. If it feels damp, skip the water for now and check again later.
