When is the Best Time to Divide Orchid Plants
As a traditional famous Chinese flower, dividing orchid plants is an important propagation method to maintain the health of the plant. Mastering the correct timing and operation essentials can prevent damage to the mother plant and improve the survival rate of new seedlings. This article will provide a detailed analysis of the best timing and scientific operation steps for dividing orchid plants.
I. Choosing the Golden Time for Dividing Orchid Plants
1. Advantages of Dividing During the Dormant Period
The best time to divide orchids is after flowering and before the new buds sprout, as the plant is in a dormant state with low root activity. Statistics show that dividing at this time can increase the survival rate to over 90%, 35% higher than dividing during the growing period.
2. Variety Difference Comparison Chart
Spring Orchid (divide in February-March), Jian Orchid (divide in September-October), Hui Orchid (divide in March-April), Mo Orchid (divide in November-December), Han Orchid (divide in April-May).
II. Full Process Analysis of Dividing Orchid Plants
1. Preparation Before Dividing
Choose a well-ventilated purple sand or ceramic pot, with the new pot diameter 5cm smaller than the original pot. Prepare disinfected scissors, charcoal powder, and carbendazim solution, and it is recommended to stop watering 2 days in advance.
2. Scientific Pot Removal Techniques
Gently tap the pot wall to loosen the planting material, invert the pot, and slowly remove the plant. When rinsing the roots with water, the water temperature should be close to room temperature, and the rinsing time should be controlled within 3 minutes.
3. Precise Dividing Operations
Find the natural tillering point, ensuring that each cluster retains 3-5 complete fleshy roots and 2-3 pseudobulbs. After applying charcoal powder to the cut, it is necessary to expose the roots for 1-2 hours to promote wound healing.
4. Key Points for Potting and Care
Use new planting material (bark: perlite: stone = 5:3:2), with planting depth allowing the pseudobulb to be exposed by 1/3. Place the potted plant in a scattered light area and maintain an environmental humidity of 70%-80% for 15 days.
III. Post-Dividing Management Norms
Avoid fertilizing for 20 days after dividing, and only apply a 2000 times diluted orchid-specific fertilizer after new roots grow 2cm. In the summer, it is necessary to enhance ventilation, and in the winter, pay attention to insulation. Regularly rotate the pot to ensure even light exposure.
