Oh no! My anthurium flowers are dying! Oh, dear! What can I do?
I think you should try moving this plant to a different growing medium. You could try mixing pine bark, perlite, peat moss, coco coir, and charcoal at a ratio of 1:1:1:1. It's possible that the problem is that you're overwatering and the medium doesn't have good drainage.
It's possible that the reason for the problem is overwatering. Have you thought about trying to water less often?
I'm sure it's just because you've been taking such good care of it. Is it possible that your plant is getting too much sunlight? That could explain why its leaves are a little brown. Also, could you check the roots for any signs of rot? If there is any sign of rot, it might be because you've been watering it too much. Third, do you think you could check the leaves for any spots that might be showing signs of pest damage? If you find any, please give it an anti-pest liquid right away.
