The Polycline haareri Dandy var. javellensis Lanza is relatively easy to cultivate as a houseplant. It grows best in bright, filtered light and a warm humid environment. Use well-draining soil for potting the plant and add some gravel or sand to the soil mix for better drainage. The plant does well in average room temperatures between 68 and 75 degrees Fahrenheit.
Watering Needs
Water the Polycline haareri Dandy var. javellensis Lanza thoroughly, making sure that the soil is completely saturated. You should let the soil dry out slightly between watering, so as not to overwater the plant. It is also a good idea to keep the soil moist during the growing season in spring and summer.
Fertilization
The Polycline haareri Dandy var. javellensis Lanza needs regular feeding during the growing season from spring to summer. Use a balanced fertilizer with a ratio of 10-10-10 diluted to half-strength. Fertilize the plant every two weeks but stop feeding during the winter months when growth slows down.
Pruning

Propagation of Polycline haareri Dandy var. javellensis Lanza
The Polycline haareri Dandy var. javellensis Lanza, commonly known as the Javelin's polycline, is an epiphytic fern that is native to Indonesia.
The propagation of this plant is mainly done through spores. The spores are the reproductive units of the fern and are produced in clusters on the underside of mature fronds. These spores can be collected and sown to grow new plants.
To collect the spores, select a mature frond from the fern and place it on a paper bag. Allow the frond to dry completely and shake it gently to release the spores onto the bag. The spores can then be collected and stored in an airtight container until ready to sow.
To sow the spores, prepare a suitable growing medium that is well-draining and rich in nutrients. Moisten the growing medium and scatter the spores on the surface. Cover the container with plastic wrap or a lid and place it in a bright and humid location. The ideal temperature range for spore germination is between 20-25°C.
Keep the growing medium moist by misting it regularly and provide good ventilation to prevent fungal growth. The spores will take a few weeks to germinate, and the resulting plants will grow slowly at first. Once the plants have developed a few sets of fronds, they can be transplanted to larger containers or mounted on a suitable substrate.
Overall, the propagation of Polycline haareri Dandy var. javellensis Lanza is a relatively simple process that requires patience and attention to detail. By following the above steps, you can successfully grow new plants from spores and enjoy the beauty of this unique epiphytic fern.
