The Cultivation Method and Precautions of Wu Bing Yu
Looking at the fluffy leaves of Wu Bing Yu glistening with silver light in the sunshine at the succulent exhibition, do you also want to replicate this unique texture at home? This small succulent, native to South Africa, with its starry fluff and winter growth characteristics, is becoming a new favorite on urban windowsills. However, if you want to achieve the exhibition-level fluff texture, these nurturing details must not be overlooked.
Mastering the Three Growth Codes
Key Period of Light Control
In the growing seasons of spring and autumn, it requires 6 hours of direct sunlight daily, with a south-facing windowsill being the most ideal. During the summer dormancy, move it to a place with scattered light and remember to avoid the midday strong light that can burn the new fluff. In winter, it can accept all-day soft sunlight, and when using a supplementary light, maintain a distance of 30cm.
Golden Rule of Watering in All Seasons
In spring and autumn, use the "soak pot" method to water once a week, and water again when the potting soil is completely dry. During the dormancy period from June to August, completely stop watering, and in September, start with spraying and then give a small amount of water. In winter, keep it slightly moist when the room temperature exceeds 15°C, and control the water below 10°C to prevent frostbite.
Soil Preparation Determines Success or Failure
Recommended formula: volcanic rock: red jade soil: peat = 5:3:2 for breathability, with a 3cm layer of ceramsite at the bottom of the pot for drainage. When repotting every year, keep 1/3 of the heart soil, and mix 5% rice husk charcoal into the new soil to prevent root rot.
Avoiding the Five Major Maintenance Minefields
Taboos in Dormancy Management
The Cultivation Method and Precautions of Wu Bing Yu
Watering by mistake during the high temperature of summer can lead to root rot, and ventilation needs to be strengthened during the plum rain season. If the base turns black, immediately remove the pot and repair the roots, soak in carbendazim, and then air the roots for 3 days before changing to new soil.
Breaking the Stagnant Seedling in Winter
When the temperature continuously drops below 4°C, it will stop growing, at which time it should be moved to a closed balcony and a mini greenhouse should be set up with insulation film. Open the film for ventilation at noon for 2 hours weekly, maintaining a day and night temperature difference within 8°C.
Taboos in Indoor Placement
Although suitable for indoor maintenance, long-term distance from natural light can lead to the degeneration of fluff. It is recommended to place it on the windowsill for natural light for 3 days a week and use a rotating tray to ensure even light exposure.
Advanced Propagation Techniques
Sowing is recommended to choose around the spring equinox, lay fresh seeds flat on the surface of moist vermiculite, and cover with plastic wrap to maintain humidity. After germination, gradually uncover the film to harden the seedlings, and transplant after the true leaves spread. Mature plants can be propagated by division, but it is important to retain the complete fibrous roots.
By precisely controlling the light cycle and water supply, combined with a breathable medium, even beginners can grow Wu Bing Yu with distinct fluff. Remember its special habit of "growing in winter and dormant in summer," avoid the trap of high temperature and humidity, and this little精灵 from South Africa will surely bloom with unique charm on your windowsill.
