How to Pot Clivia Miniata Seedlings
As a widely popular ornamental plant, the transplantation of Clivia miniata seedlings is an important step in cultivating high-quality plants. Mastering scientific potting techniques can not only improve the survival rate but also lay the foundation for subsequent growth. This article will systematically explain the key points of the entire process from potting soil preparation to post-transplant care.
Ⅰ. Pre-potting Preparation
1.1 Key Points for Choosing a Pot
The best choice is an unglazed ceramic pot with a diameter of 10-12 cm, which should have 3-4 drainage holes at the bottom. New pots should be soaked for 24 hours to remove alkaline substances, and old pots should be sterilized with boiling water.
1.2 Scientific Substrate Mixture Ratio
It is recommended to use a mixed substrate of peat soil: perlite: pine bark in a ratio of 5:3:2, with a pH value controlled between 5.5-6.5. Add 3g of decomposed sheep manure as a base fertilizer per liter of soil.
Ⅱ. Standard Process for Seedling Treatment
2.1 Health Check of the Root System
Gently shake the roots with a bamboo skewer to remove decayed roots. Retain healthy fleshy roots that are longer than 8 cm, and keep 3-5 main roots after pruning.
2.2 Disinfection Operation Standards
Soak in a 0.1% potassium permanganate solution for 5 minutes, then rinse under running water for 20 seconds. Apply charcoal powder to the wounds to cover the entire section, and control the drying time of the roots between 2-3 hours.
Ⅲ. Steps for Scientific Potting
3.1 Substrate Pre-treatment
Adjust the substrate moisture to 40% with a spray bottle 24 hours in advance, with the standard being able to form a ball when held in hand but dispersing when touched. Lay a 3cm thick layer of ceramsite as a drainage layer at the bottom of the pot.
3.2 Key Points of Planting Technique
The planting depth should allow 1/3 of the pseudobulb to be exposed, with the roots spread out like an umbrella. When backfilling, gently lift the plant to ensure close contact between the roots and soil, with a compaction force of 300g/cm².
Ⅳ. Post-potting Care Management
4.1 Environmental Control Parameters
Maintain an ambient temperature of 18-25°C and an air humidity of 60%-70%. Avoid direct sunlight for the first two weeks and use a shade net to maintain a light intensity of 5000Lux.
4.2 Water and Fertilizer Management Cycle
Water thoroughly along the edge of the pot 7 days after planting, then maintain a substrate moisture content of 20%-30%. Do not fertilize before the new leaves unfold, and after 45 days, apply a 1500 times dilution of "Flower More No.1".
Through standardized potting operations and scientific care management, the survival rate of Clivia miniata seedlings can reach 95% or more. The key is to grasp the three principles of thorough disinfection, root expansion, and proper slow acclimatization. It is recommended to check the substrate EC value monthly and adjust the care plan in a timely manner to ensure healthy growth of the plants.
