What a gorgeous low light friend. The Mahogany fern is an easy-to-care for, beautiful plant that we love for its deep and rich colors!
Ferns like medium to bright indirect light. Water when the top 1-2" of soil is dry, and keep them above 50% humidity (a pebble tray would work great for these guys). Keep them away from cold drafts or hot air drafts, and you should have a happy fern!
