CULTIVATION CONDITIONS: PYRROSIA LINGUA 'CRISTATA'
Light
Lively, but indirect. This fern appreciates good light to optimize its growth, but it must be protected from direct sun, especially in summer, which could burn its tough fronds.
Watering
Moderate and Spaced. Allow the substrate to dry slightly between waterings. The plant is sensitive to excess moisture, especially in its rhizome. Watering should be reduced in winter.
Substrate / Support
Ultra-Draining (Imperative). Use an aerated orchid-type mix (bark, sphagnum, coconut) or special fern mix . It is often grown directly mounted on a plate (cork, bark) or rock.
Rhizome
Not Buried. The golden rule: the creeping rhizome of Pyrrosia must never be covered by the substrate , otherwise it will rot. Let it run on the surface.
Temperature / Humidity
Room Temperature. Ideally between 15 and 25°C. Although it is cold tolerant (depending on the strain), the ' Cristata ' variety is generally grown indoors, in a conservatory or temperate/cool terrarium.
Hygrometry
Appreciates atmospheric humidity, making it perfect for a well-ventilated collector's terrarium.
Fertilization
Very Low. If necessary, very light fertilization with a quality special fern fertilizer , applied during the growing season (spring-summer). Never overdose.
Use
Indoor plant, terrarium, veranda or winter garden. Very graphic collector's item.
