How to Repot Euphorbia Jiphyllum
Euphorbia Jiphyllum is favored by succulent enthusiasts for its unique patterned appearance, but this large succulent often faces the challenge of repotting during care. The correct repotting method not only affects the aesthetic of the plant's shape but is also crucial for the healthy development of the roots. This article will systematically analyze how to scientifically complete the repotting operation through four core steps.
Preparation Phase for Repotting Euphorbia Jiphyllum
Principles for Container Selection
The root diameter of mature Euphorbia Jiphyllum can reach 30-40 cm, so it is recommended to choose a ceramic pot 5 cm larger than the original one. The earthenware material has a breathable pore structure, and combined with 3-4 drainage holes at the bottom, it can effectively prevent waterlogging and root rot. Young plants should be repotted every spring, while mature plants every 2-3 years, and observe if there are any root overflow signs at the bottom of the pot.
Key Points for Substrate Configuration
Use a golden ratio of 3:2:1 (coarse sand 3 parts/garden soil 2 parts/vermiculite 1 part), and add 10g of bone meal and 5g of wood ash per liter of substrate. This structure ensures both drainage and provides calcium, potassium, and other trace elements. Test the substrate's water permeability: pour 200ml of water into a container filled with substrate, it should completely penetrate within 10 seconds.
Repotting Process of Euphorbia Jiphyllum
Technique for Removing the Plant from the Pot
Stop watering 7 days in advance to dry the potting soil, and use a gardening spade to circle the pot wall to loosen the soil. Support the base of the stem and invert the pot, gently tapping the pot wall to remove the soil mass intact. Avoid pulling or tugging to prevent damaging the surface aerial roots.
Root Treatment Standards
Use a bamboo skewer to remove 50% of the old soil, keeping the central protective soil. The pruning tools should be disinfected with 75% alcohol,剪除 the brown aging roots and black decayed roots, keeping the healthy white roots. After pruning, let the roots dry for 24 hours to allow the cuts to heal completely.
Key Points for Post-Repotting Care of Euphorbia Jiphyllum
Planting Operation Details
Place a 3cm layer of ceramic stones at the bottom of the pot for drainage, then add 1/3 of the substrate and place the plant. Maintain a 2cm gap between the original soil surface and the pot opening, and gently lift the plant while filling the soil to make the roots spread out. After filling the soil, water around the edge of the pot to settle the roots, and use the immersion method to moisten the substrate.
Management During the Acclimatization Period
Place the plant in a散射光通风处 for 2 weeks to recover, maintaining an environmental temperature of 18-25℃ during this period. Gradually increase light exposure after new leaves appear, and use a 50% diluted specialized succulent fertilizer, supplemented with trace elements once a month.
Scientific repotting can promote the root renewal of Euphorbia Jiphyllum, and it is recommended to perform the operation during the spring and autumn growing seasons. After repotting, appropriate water control and light adjustment can help the plant quickly recover its growth momentum and display more vibrant patterns.
