Doodia is a genus of ferns that belongs to the family Blechnaceae. It is native to Australia, New Zealand, and some parts of Asia. The name Doodia comes from the Greek word “dodone,” which means nettle. There are currently around 20 species of Doodia recognized by botanists. These ferns are often grown for their beautiful foliage and are commonly used in landscaping and as indoor plants.

Taxonomic Information

Appearance

The fronds of Doodia ferns are typically evergreen and range from light to dark green in color. They can be up to 50cm long and are generally lance-shaped with a slightly wavy edge. The rachis is dark brown or black and has small scales covering it. The spores of Doodia are produced on the underside of the frond and are oval-shaped.

Care Guide

Doodia ferns are relatively easy to care for and can be grown both indoors and outdoors. Here are some important care tips:

• Water: Doodia ferns prefer consistently moist soil, but avoid overwatering as this can lead to root rot. Water when the top layer of soil feels dry.
• Fertilization: Use a balanced liquid fertilizer once a month during the growing season (spring and summer).
• Soil: Doodia ferns prefer well-draining soil that is rich in organic matter.
• Sunlight: Doodia ferns prefer bright, indirect light. Avoid direct sunlight as this can scorch the leaves.
• Hardiness Zones: Doodia ferns prefer a warm and humid climate and are suitable for USDA hardiness zones 9-11.

Common Pests & Diseases

Doodia ferns are relatively resilient to pests and diseases, but they can be susceptible to mealybugs, spider mites, and scale insects. To prevent these pests, keep the air around the plant humid and free of dust. If you notice any signs of infestation, treat with an insecticidal soap or neem oil. Doodia ferns can also be affected by root rot, which is caused by overwatering or poorly draining soil. To prevent root rot, make sure the soil dries out slightly between waterings and ensure that the pot has adequate drainage.

Habitat

Doodia ferns are native to Australia, New Zealand, and some parts of Asia. They are often found in damp, shady areas such as rainforests and woodland habitats. Some species of Doodia are also found in alpine regions.
