An easy-to-grow fern, Button Fern (a.k.a. Pellaea Rotundifolia) is perfect for those who are new to plants or have a difficult time keeping them alive.

Light Needs

It does best in indirect light but can also tolerate low light conditions. A window facing east or west will be a happy place for your fern to thrive. If you cannot provide indirect light, it will do just fine under fluorescent lighting.

How Often to Water Button Fern

They like to be kept moist at all times but not soggy. The potting mix should be allowed to dry out slightly in between waterings. Button Ferns are very sensitive to fluoride and chlorine, so it is best to use distilled or rainwater when watering your plant.


Fertilize them monthly during the growing season with a balanced liquid fertiliser. Be sure to dilute the fertilizer to half the recommended strength to avoid burning the roots of your plant.


A well-draining potting mix that also retains water without becoming soggy is perfect for growing your Button Fern. A mixture of two parts of peat moss and one part perlite or sand will work well. Be sure the potting mix is well-draining to avoid root rot.

When To Repot Button Fern

Repot your plant every two to three years in the springtime. Take out the fern gently from the pot and place it into a pot that is only one size larger than the current pot. Be sure to use a well-draining potting mix and water the plant thoroughly after repotting. You can also divide your plant while repotting.


They prefer high humidity between 40-50%, so if the air in your home is too dry, consider placing your fern on a pebble tray or humidifier.


Button Ferns like to be in cooler temperatures between 60-75°F (15-24°C).

How To Propagate Button Fern

Button Fern can be propagated by the division method. For division, simply cut the rhizome into two or three pieces and put each piece up in its own pot. Be sure to use a well-draining potting mix and water the plant thoroughly after propagating.

Other Names

Round-leafed fern, Pellaea Rotundifolia.

FAQs and Common Problems

Button Fern usually does not cause any problem for the growers, but after a few years, it starts looking untidy due to overgrowth, so trim your plant in spring, especially the wilting and the yellowing leaves.
