I love this plant. It has a lot of personality with its leaves and wire like stems. Like my other ferns, this fern requires some attention. It drinks a lot of water, requiring watering every 2-3 days. I keep it in a pot with drainage and check the soil every day with a chopstick. If it is almost dry I give it water. If you let it dry out completely between watering the leaves will curl up. If you get water to it fast enough they recover very quickly. If you aren’t able to tend to you plants daily, this is not the plant for you.

Eh as much as I love this plant it kinda sucks. I've only ever had one leaf on it, it won't grow or die, so that's something. Honestly if anyone has advice for me I'll kinda do anything.

This plant was so lovely when I brought it home from the nursery for like three days and since then I can’t make it happy. The once-gorgeous leaves are now crispy and dried up even though I’m still tending to it and it’s not dead. Very finicky

I want to like my heart fern so bad but it’s constantly browning and dying. It won’t grow. I have it in the shade and it still dries up constantly. What am I doing wrong with this plant lol
