I got my anthurium a week ago at a nursery, and I think it’s stressed. Its spathe came with that dark spot. It’s been misted twice this week, was watered when it repotted, and watered again today (the soil monitor said its water was almost dry). It’s in indirect, bright light in my dining room. I just purchased a humidifier and am hoping that might help? *My zebra plant is in the same room and is stressed as well. Any advice would be greatly appreciated!
