Does the Bi Lei Gu plant need sunlight?
As a star variety among block-root plants, Bi Lei Gu is deeply loved by succulent enthusiasts for its unique shape and rough texture. However, many beginners are confused about balancing light intensity and care elements during maintenance. This article will systematically sort out the scientific methods of light management based on its native characteristics.
The impact of light on the growth of Bi Lei Gu
Basic light requirements
Bi Lei Gu, native to the island of Madagascar, receives 6-8 hours of scattered light per day in the natural environment. When maintaining it at home, it is recommended to maintain more than 4 hours of morning light, and avoid the strong UV radiation period from 11-3 pm in summer. In winter, it can be extended to 6 hours of direct sunlight.
Special seasonal management
During the plum rain season, it is necessary to complement the light cycle with grow lights, using full-spectrum LED lights 40 cm away from the plant, supplementing light for 2-3 hours per day. During the high-temperature dormancy period (above 32°C), it should be moved to a bright scattered light environment to avoid sunburn on the epidermis.
Comprehensive maintenance techniques
Substrate mixing scheme
It is recommended to use a mixed substrate of red jade soil (40%) +鹿沼土 (20%) + volcanic rock (15%) + decomposed leaf soil (15%) + bamboo charcoal particles (10%), with a pH value controlled between 6.0-6.8. Add 5% bone meal as a long-acting calcium source during potting in spring every year.

Water control standards
Adopt the "dry-wet alternation method": water thoroughly after the substrate is completely dry in spring and summer, with an interval of about 7-10 days. Extend it to 15-20 days in autumn and winter, using softened water at about 25°C. Special note: the appearance of wrinkles at the base of the tuber is a signal of water shortage, but it should not be watered excessively immediately.
Nutrition supply strategy
In the growing period (18-28°C), apply a slow-release fertilizer with NPK=3-12-12 once a month, and complement it with foliar application of seaweed extract (diluted 2000 times) every quarter. Stop fertilizing during the dormant period to avoid salt accumulation causing root damage.
By precisely controlling light intensity and cycle, combined with scientific substrate management and water and fertilizer programs, Bi Lei Gu can maintain a compact plant shape and show its unique silver-gray epidermis. It is recommended to regularly observe the development of new thorn seats and adjust maintenance parameters in time to let this desert spirit show its best condition.
