Living Stone Plant Repotting Tutorial
As the 'living gem' of the succulent world, repotting living stone plants is a crucial operation for maintaining plant health. This article, based on 12 years of gardening experience, provides a detailed explanation of the complete process from removing the plant from its pot, pruning the roots, to transplanting and caring for the plant, helping you easily master the scientific management methods for epidermal succulents during their shedding period.
One: Strategies for Choosing the Right Time for Repotting
1.1 Regional Climate Differences
In the northern regions, it is recommended to perform the operation in autumn (September-October), when the day-night temperature difference is over 10°C, and the air humidity is between 40%-60%, which is the most suitable. In the southern regions, it can be postponed to November-December, avoiding the plum rain season to ensure the wounds are dry.
1.2 Plant Condition Assessment
When you find that the roots are extending from the drainage holes, the potting soil is compacted, or the plant cluster is filling the pot, it is the best time for repotting. Special attention should be paid to avoid the flowering period and the shedding period.
Two: Golden Rules for Root Treatment
2.1 Pot Removal and Drying Treatment
Stop watering 7 days in advance and use the 'pot wall tapping method' to loosen the soil. For cluster plants, you can use a bamboo skewer to circle the pot wall to separate them, ensuring that the main roots are kept over 5cm long.
2.2 Root Pruning and Disinfection Standards
Keep the thick main roots and cut off the fine roots to 1cm. Use 75% alcohol to disinfect the pruning shears, apply carbendazim (at a concentration of 1:1000) after pruning, and let it dry for over 72 hours.
Three: Scientific Substrate Mixture Solutions
3.1 Ideal Substrate Formula
Recommended particle soil composition is 70%: Akadama soil (3-5mm) 40% + volcanic rock 20% + diatomaceous earth 10%, mixed with 30% decomposed leaf soil. Add bone meal (5g/L) to promote root growth.
3.2 Pot Selection Essentials
Choose a thick陶 pot 3cm larger in diameter than the plant, with a depth of 8-10cm. Place a 2cm thick layer of ceramsite at the bottom of the pot to enhance drainage and prevent root rot.
Four: Key Points for Post-Transplanting Care
4.1 Planting Operation Standards
Use the 'sit-in pot watering method': first lay 3cm of substrate, place the plant, and fill the soil up to 1cm from the edge of the pot. Adjust the angle with forceps to ensure the growing point is level with the soil surface.
4.2 Management During the Acclimatization Period
Avoid sunlight for 72 hours after transplanting, maintain a temperature of 20-25°C. Start with scattered light on the 4th day, and after 2 weeks, return to normal care. Do not fertilize within 1 month.
Mastering these four key aspects will help the living stone plant recover quickly after repotting. It is recommended to repot annually in conjunction with the growth cycle, and proper root pruning can effectively stimulate the growth of new roots, keeping the plant vigorous. Remember to observe the plant for 2 weeks after repotting; slight wrinkling is normal, and avoid watering too early.
