Button Fern Turning Brown

I bought a Button Fern a few months back from Walmart. It has a self watering stick. Idk if I am over watering it or what. I’m hoping that you can help me. I named it Pendleton so I really hope that I can get it to come back.

Hi Sarah,

 If just leaf tips are turning brown the air is too dry or too warm. If entire branches are turning brown, the soil is staying too wet. Here are some care tips for a Button fern. (If you could email a close up of the leaves I could be more helpful.)
Light: Bright light, but no direct sun

Water: Water well then allow the top few inches of soil to dry out before watering again. Fronds that are brown/yellow and wilted are a sign of overwatering.

Humidity: Moderate to high humidity. Use a humidifier if necessary

Temperature: Normal room temperatures 60-75°F/16-24°C

Soil: Loose fast draining soil

Fertilizer: Feed monthly with a liquid fertilizer diluted to 1/2 the recommended strength when the plant is actively growing.
