Blechnum appendiculatum is a fern in the family Blechnaceae. It is commonly known as hammock fern, sinkhole fern, and New World midsorus fern. Its native range is from the southern United States through Mexico, the Caribbean and Central America to western South America. It grows in rocky hammocks and moist forests.
Palm fern typically shows strong resistance to disease and encounters relatively few insect pests. Its care is rated difficult because it needs a moist environment and frequent watering. Yet its roots are vulnerable to rot if overwatered or if the surroundings lack proper ventilation. Palm fern is appropriate for those with some growing experience, as most people can keep it alive for a period of time. Nevertheless, it may have difficulty thriving and its leaves can dry out and become less healthy as time goes on.
How to keep Blechnum Appendiculatum.
Light
Palm fern comes from habitats such as forest understories or rocky locations that provide natural shade. It prefers Full Shade, though it can tolerate Partial Sun.
Temperature
The palm fern comes from tropical areas where the climate is generally warm and humid. Consequently, it is adapted to high heat and moisture. It dislikes rapid temperature changes and prefers a steady thermal environment, so avoiding indoor temperature fluctuations is important. It typically cannot tolerate cold and needs higher temperatures to grow. If the surrounding temperature falls too low, the plant may stop growing or even die.
Pruning
Pruning palm ferns in early spring is beneficial for their growth and health. By removing dead fronds, you can enhance the plant's shape and encourage new growth. This practice improves air circulation, reduces the risk of fungal infections, and supports the development of strong fronds. Overall, early spring pruning is essential for maintaining the plant's health and visual appeal.
