Taxonomic Information

Appearance

Thelypteridaceae ferns have fronds that are typically pinnate or bipinnate, meaning they have a feather-like appearance. The fronds can vary in size and shape depending on the species, but they are usually green in color. Some species have fronds with a silvery or reddish hue. The spores are produced on the undersides of the fronds and are usually covered by a thin membrane called an indusium.

Care Guide

Thelypteridaceae ferns can be grown both indoors and outdoors, but they require specific care to thrive:

• Water: These ferns prefer moist, well-draining soil. Water them thoroughly whenever the top layer of soil feels dry to the touch.
• Fertilization: Use a balanced liquid fertilizer every 2-3 weeks during the growing season to encourage healthy growth.
• Soil: Use a well-draining potting mix that is rich in organic matter, such as peat moss.
• Sunlight: These ferns prefer partial to full shade, although some species can tolerate more sun. Avoid exposing them to direct sunlight for extended periods of time.
• Hardiness Zones: Thelypteridaceae ferns are typically hardy in zones 8-11, but some species can tolerate colder temperatures.

Common Pests & Diseases

Thelypteridaceae ferns can be susceptible to a variety of pests and diseases:

• Aphids: These small insects can feed on the sap of the plant and cause stunted growth and yellowing leaves. Use an insecticidal soap to control them.
• Scale: These pests can cause yellowing and wilting of the fronds. Use an insecticidal soap or horticultural oil to control them.
• Root rot: Overwatering or poorly-draining soil can cause root rot, which can cause the plant to wilt and die. Use a well-draining potting mix and avoid overwatering.

Habitat

Thelypteridaceae ferns can be found growing in a variety of habitats:

• Forests
• Wetlands
• Rocky outcrops
• Shaded areas
