Drynaria roosii, commonly known as gu-sui-bu, is a species of basket fern of the family Polypodiaceae. The plant is native to Eastern Asia, including eastern China.
Gu-sui-bu generally resists disease effectively and has relatively few insect pests. Its care is considered difficult, because it needs a moist environment and frequent watering. However, the roots are susceptible to rot if overwatered or if the surroundings are poorly ventilated. Gu-sui-bu is suitable for those with some growing experience, as most people can keep it alive for a while. Still, it may struggle to thrive and its leaves can dry out and decline in health over time.
How to keep Drynaria Roosii.
Light
Gu-sui-bu is native to habitats like forest understories or rocky terrain that provide natural shade. It prefers Full Shade but can tolerate Partial Sun.
Temperature
Gu-sui-bu comes from tropical areas, where the climate is typically warm and humid. As a result, it is well-suited to high temperatures and humidity. It is sensitive to sudden temperature changes and prefers a stable temperature environment, so indoor temperature fluctuations should be avoided. It generally does not tolerate cold and requires higher temperatures for growth. If the environmental temperature falls too low, the plant may stop growing or even die.
