Attention Points for Repotting Clivia Miniata
As a popular indoor foliage plant, the repotting process of Clivia Miniata directly affects its growth condition. This article systematically analyzes the key points of the repotting process from timing selection to post-repot care, helping you master essential techniques.
Core Guidelines for Clivia Miniata Repotting
Best Timing for Repotting
The most suitable time for repotting is from March to April when the temperature is stable at 15-25°C. At this time, the plant is in the growing stage and can quickly repair root damage. Avoid repotting in the high summer temperatures (＞30°C) which can easily cause bacterial infections, and avoid the low winter temperatures (＜10°C) which can lead to root frostbite.
Illustrated Standards for Root Pruning
Remove brown old roots, entangled roots, and weak fibrous roots, retaining 1/3 of the main root system length. Tools must be disinfected with alcohol, and the cut should be smooth to reduce the risk of infection. After pruning, let the plant sit for one hour to allow the wounds to scab before repotting.
Golden Ratio for Substrate Formula
The best mixed substrate is a combination of decomposed leaf soil: pine bark: river sand at a ratio of 5:3:2. Adding charcoal particles (10% of the mixture) can adjust the pH value, and coconut bran (15% of the mixture) enhances water retention. Change the soil every 2 years to ensure nutrient supply.
Key Points for Post-Repotting Care
Control of the First Watering Time
Water thoroughly within 24 hours after planting with water at the same temperature as the environment. Use a long-spout pot to slowly seep water around the pot edge, avoiding root rinsing. Maintain the substrate slightly moist, and return to normal watering frequency after 7 days.
Environmental Control Essentials
Keep a scattered light environment (light intensity of 3000-5000 LUX) and stable temperature at 18-22°C. For the first 3 days, you can cover with a transparent plastic bag to maintain humidity, and ventilate for 2 hours daily. The unfolding of new leaves indicates successful acclimatization.
By precisely controlling the timing of repotting and scientific care, the survival rate of Clivia Miniata can be increased to over 95%. It is recommended to repot every 2 years in conjunction with division, which can update the substrate and propagate new plants, achieving dual value in both ornamental and care aspects.
