When is the Best Time to Repot Succulents
As the most concerning care operation for succulent enthusiasts, the timing of repotting directly affects the survival rate of the plants. This article deeply analyzes the golden rules of repotting succulents by combining scientific experimental data with the experience of seasoned players, especially providing professional advice for the repotting scenario in November.
Golden Time Window for Repotting Succulents
Best Repotting Period in Spring and Autumn
Experimental data shows that the root activity of succulents increases by 40% in an environment with a temperature of 15-25°C. March to May and September to October are ideal repotting periods, when the day-night temperature difference reaches 8-10°C, and combined with 65% air humidity, the success rate of potting can be increased to 90%.
Key Points for Repotting in Special Seasons
Repotting in November requires ensuring that the room temperature is greater than 18°C and stable, using ceramic pots which maintain a temperature 3-5°C higher than plastic pots. It is recommended to use plant growth lights, extending daily exposure to 12 hours, and the air flow rate should be controlled below 0.3 m/s.
Scientific Repotting Operation Guide
Root Preprocessing Specifications
Stop watering 7 days before removing the pot, and soak in a solution with 3‰ carbendazim. Trim the roots to retain the main root length of 5-8 cm, and the drying time equals twice the diameter (mm) of the incision, such as 4 hours for a 2mm diameter.
Substrate Formula Upgrade
Recommended golden ratio: peat soil 40% + red jade soil 30% + vermiculite 20% + rice husk charcoal 10%. For repotting in November, increase the particle ratio to 70% and mix in 5% wood ash to enhance cold resistance.
Post-Planting Care Techniques
Use the moist soil method, initially controlling the humidity at 30%. Keep the plant in complete shade for the first 3 days, and gradually increase scattered light from the fourth day. Use HB-101 vitality compound during the potting period, diluted to 0.01%.
Risk Prevention and Control in Special Seasons
If a cold wave occurs after repotting in November, a double-layer insulation method can be used: cover the inner layer with non-woven fabric and the outer layer with a transparent plastic bag. Ventilate for 1 hour every noon, and pause watering when the substrate temperature is below 15°C.
By scientifically adjusting environmental parameters, succulents can still achieve a success rate of over 75% when repotted in November. It is recommended for beginners to prioritize operations in spring and autumn, while experienced players can try repotting in special seasons with adequate equipment.
