"Clivia Miniata" in February
February is the golden period for repotting Clivia Miniata, as the plants end their dormancy and enter the growing stage. Proper repotting can activate root vitality. The scientific four-step method of unpotting, root pruning, soil mixing, and care can not only restore the luster of the leaves but also promote the differentiation of flower buds in spring. Master the following professional gardening techniques to help your Clivia Miniata recover quickly after repotting.
Key Points of Unpotting
Water Control and Timing of Unpotting
Stop watering 7 days before repotting, and operate when the soil moisture drops to 30%. Use bamboo slices to loosen the soil along the pot wall, and support the soil ball when inverted to completely retain the protective heart soil. Special note: If red-brown fleshy roots are exposed, it indicates that the plant is ready for repotting.
Root Refinement Treatment
Three-Level Root Pruning Standard
Divide the roots into three levels for treatment: ① Retain main roots with a diameter > 2mm that are white; ② Prune secondary roots that are black and rotting; ③ Remove all dead capillary roots completely. After pruning, soak the roots in a 800x solution of carbendazim for 20 minutes, and maintain an environmental humidity of 60% during root drying to prevent root tips from drying out.
Scientific Substrate Mixing Ratio

Analysis of Special Soil Formula
It is recommended to use a golden ratio of decomposed pine needles (40%), calcined ceramsite (30%), oak charcoal (20%), and bone meal (10%). When filling soil, gently戳 the soil with a stick to make the substrate adhere to the roots, place 3cm of broken tiles at the bottom of the pot to form a drainage layer, and leave a 2cm watering space at the edge of the pot.
Seedling Care Regulations
Three-Stage Light Management
After repotting, follow a three-stage care plan: ① For the first 5 days, provide scattered light; ② From the 6th to the 10th day, increase 2 hours of morning light; ③ After 10 days, resume full sunlight. Combine this with foliar application of potassium dihydrogen phosphate (1500x solution) and supplement with decomposed sesame cake fertilizer water every 15 days, which can increase the leaf width by over 30%.
By mastering the golden period of repotting in February, performing systematic operations in three dimensions including root activation, substrate renewal, and scientific seedling care, not only can the leaves of Clivia Miniata become thicker and brighter but also store sufficient nutrients for spring flowering. It is recommended to choose a breathable ceramic pot with a diameter of 15-20cm for repotting every year based on the plant's growth, and combine regular pot rotation care to keep the plant's shape always perfectly symmetrical.
