How to Make Orchids Sprout More
Orchids, as representatives of elegant flowers, their germination rate directly affects the ornamental value of the plants. Mastering the correct maintenance methods combined with scientific fertilization can make the orchid plants sprout 2-3 times a year. This article systematically analyzes the core techniques to promote orchid germination from substrate proportion to nutrient management.
Three Elements of Environmental Control
Golden Substrate Proportion
It is recommended to use a combination of pine bark (40%) + volcanic rock (30%) + coconut shell (20%) + perlite (10%), ensuring that the substrate porosity reaches 35% or more. The substrate needs to be replaced every 2 years to prevent acidification and caking, which can affect root development.
Balance of Light and Shadow
In spring and winter, provide 4-6 hours of soft light daily, and use double-layer shading nets in summer. The intensity of light can be judged by the color of the leaves: dark green needs additional light, and yellowish-white needs shading.
Water Management Cycle
In spring and autumn, water thoroughly every 3-5 days, mist twice a day in summer to increase humidity, and extend to every 7-10 days in winter. Use the bamboo stake insertion method to test humidity, and if no clay adheres when pulled out, it's a signal to water.
Nutrition Supply Plan
Bottom Fertilizer Fermentation Technique
Mix peanut shells and sheep manure in a ratio of 3:1, seal and ferment for 60 days before use. Add 50g of bottom fertilizer per liter of substrate, continuously releasing nitrogen, phosphorus, and potassium elements.
Fertilization Strategy During the Growing Period
Use Flower Treasure No. 1 (N-P-K=7-6-19) 2000 times liquid during the germination period, spray every 10 days. After the bud appears, switch to Magic Fertilizer (14-13-13), and bury the granular fertilizer at the edge of the substrate.
Key Points of Scientific Management
Technique for Inducing Sprouts by Dividing Plants
In March-April, cut the orchid plants with more than 5 seedlings, retaining 2 seedlings with 1 bud point. Apply charcoal powder to the cut surface, let it dry in a ventilated place, and then plant it in a pot.
Temperature Difference Stimulation Method
Maintain a temperature difference of 8-10°C between day and night in spring and autumn, 15-18°C at night, and 23-25°C during the day. Continuous stimulation for 3 weeks can activate dormant bud points.
By improving the substrate and precise fertilization, combined with scientific environmental management, the germination rate of orchids can be increased by 80% or more. It is recommended to record the growth data of new buds every month and adjust the maintenance plan in a timely manner. Using the methods in this article, common orchid varieties can sprout 5-8 robust new buds annually.
