How to Repot the Bi Lei Gu Plant
As a star variety in the succulent world, the Bi Lei Gu is deeply favored by gardening enthusiasts for its unique drum-shaped leaves. However, many people often damage the plant due to improper potting procedures during maintenance. This article will systematically analyze five core operational points and illustrate the professional transplanting process with real-life examples.
One, Core Steps for Repotting Bi Lei Gu
1. Techniques for Safely Removing the Plant from the Pot
Use a narrow-mouthed gardening spade to circle the pot wall to loosen the soil, and support the base of the plant when inverted. Pay special attention to the plant's fragile, easily breakable stems, and avoid pulling them forcibly. In case of a stuck pot, gently tap the bottom to help separate it.
2. Three-Step Root Treatment Process
It is recommended to use a soft-bristle toothbrush to clean the old soil, which can remove compacted soil without injuring the fine roots. The shaking method is only suitable for healthy plants, and when black rot signs are found, the soil must be thoroughly cleaned and inspected.
3. Scientific Root Pruning Guide
Keep the main root length between 3-5 cm and cut at a 45-degree angle using a curved scissor sanitized with alcohol. Identify the characteristics of diseased roots: black color/tender texture/odd smell. After pruning, let the cut surface air-dry for 2 hours.
4. Key Points of Disinfection and Care
Prepare a 1:800 solution of carbendazim, and soak for 15-20 minutes. The root-drying environment should meet the following conditions: well-ventilated scattered light/temperature 18-25°C/humidity 40%-60%. Only repot after the cut has completely calloused over.
5. Standard Planting Procedures
Choose a red or coarse ceramic pot, with 70% particle soil recommended. When planting, use a support rod to stabilize the plant, and fill the soil to 1 cm from the pot edge. It is suggested to use the immersion method for the first watering.
Two, Management Points After Repotting
During the acclimatization period, maintain a room temperature of 20-28°C and avoid direct sunlight. The appearance of new roots indicates a successful transplant, at which point you can gradually increase the light intensity. In special cases, the withering of lower leaves is a normal metabolic phenomenon.
Mastering the golden timing for repotting Bi Lei Gu (March-April in spring/September-October in autumn) and combining it with a scientific root pruning and disinfection process can significantly improve the survival rate of transplants. It is recommended to change the potting soil every 2 years, which can replenish nutrients and prevent diseases like root-knot nematodes. Remember, healthy roots are the foundation for robust plant growth, and regular checks and care can keep this "green little drummer" continuously playing the symphony of life.
