The Cultivation Method and Precautions of Coralline Fern
The delicate leaves of the coralline fern, as exquisite as jade coral, have become the new favorite of urban green plant enthusiasts in recent years. This shade-loving ornamental plant has special requirements for its growing environment, and only by mastering the correct maintenance method can it thrive indoors. We will systematically sort out the key maintenance points from light adjustment to disease prevention.
Three Elements of Environmental Control
Substrate Proportion and Container Selection
Mix peat soil and perlite in a ratio of 3:1, which can ensure loose and breathable conditions while storing nutrients. It is recommended to use a ceramic pot with a diameter of about 15cm, with a 3cm thick layer of ceramsite at the bottom to enhance drainage and prevent waterlogging and root rot.
Temperature and Humidity Balance Principle
In summer, it is necessary to spray water in the morning and evening every day, combined with the tray hydroponic method to maintain 60% humidity. During the heating season in winter, it should be kept away from radiators, and a humidifier should be used to maintain 40% air humidity, with the leaf surface wiped for dust removal every week.
Control of Light Intensity
The ideal position is 1.5 meters away from the east-facing windowsill, receiving soft morning light. In summer, a shade with 50% light blocking rate should be installed to avoid scorching the feathery compound leaves with strong noon sunlight.
Key Points of Daily Management
Accurate Watering and Fertilizing Plan
In spring and autumn, water thoroughly every 3 days, and change to half watering in the morning and evening in summer. Apply a diluted liquid fertilizer for ornamental leaves (1000 times diluted) every month, combined with adding decomposed sheep manure organic fertilizer every quarter.
Technique of Shaping and Pruning
The Cultivation Method and Precautions of Coralline Fern
When the new lateral buds exceed 1/3 of the main stem, pinch the top to promote branching by retaining 2-3 leaves at the base. Cut off the aging roots and retain the white healthy roots when repotting in spring every year.
Handling Common Problems
Solutions for Growth Stagnation
If the leaves become smaller and the leaf edges become burnt, check if the potting soil is compacted. Use the pot soaking method to soften the soil and then repot, add vermiculite to improve the structure, and use rooting powder to stimulate the development of new roots.
Measures for Disease Prevention
For the initial stage of leaf spot disease, wipe the affected leaves with garlic extract. In severe cases, cut off the infected part and spray with carbendazim. Regularly sprinkle diatomaceous earth on the surface of the potting soil, which can effectively prevent root rot disease.
Special Scene Maintenance
Indoor Placement Skills
When placing it on a desk, it should be kept 50cm away from the monitor to avoid heat sources from radiation. For tea table display, it is recommended to use an automatic water补充 flower pot, combined with LED plant growth lights for 4 hours of illumination every day.
By mastering these maintenance tips, the coralline fern can not only purify the air but also become an artwork for space decoration. Regularly observe the plant's condition and adjust the maintenance strategy in time to keep this touch of green vibrant indoors for a long time.
