Orchids potted planting steps and precautions
As a representative of traditional famous flowers in China, potted orchid planting can not only decorate the room but also cultivate one's character. By mastering scientific cultivation steps and maintenance techniques, even novices can cultivate high-quality orchids with elegant leaves and clear flowers. This article explains the step-by-step process from seedling selection to daily management to help you easily create your own orchid scenery. The four-step strategy for orchid pot planting: seedling selection and isolation techniques. High-quality seedlings are the basis for success. It is recommended to select 3-5 years old plants for isolation propagation. When dividing, keep 3 seedlings into one cluster, and pay attention to matching new buds and old stems to form a 1:2 seedling age structure. Healthy seedlings should have: plump and milky roots, complete false bulbs without black spots, and crisp leaves without scorched tips. It is recommended to use purple sand pots or vegetarian burning pots with a diameter of 10-15cm for pot utensils and substrates. The depth of the pot body must be more than 18cm to ensure that the root system is stretched. The substrate is prepared according to the ratio of pine bark: volcanic rock: humus soil to 5:3:2, and the pH value is controlled between 5.5 and 6.5. A 3-cm-thick ceramsite drainage layer is laid on the bottom of the basin, and the middle layer is backed with a grain size of 2- 3 cm. The best planting period for key points for planting on the pot is when the temperature is 15-25℃ from March to April. During operation, the top of the false bulb is flush with the edge of the pot, and the root system spreads out in an umbrella shape. When filling, tap the basin wall lightly to make the matrix dense, and finally lay a 0.5cm thick water moss to moisturize. After planting, place it in a scattered light place to slow down the seedlings for 15 days, maintaining the air humidity of more than 70%. The three-element water control strategy for orchid potted maintenance adopts the "see the dry and see the wet" watering method, which is watered thoroughly once every 5-7 days in spring and autumn, and sprayed in the morning and evening to increase moisture in summer. Use rainwater or tap water that is left standing for 3 days, and the difference between water temperature and room temperature is ≤3℃. During the growth period, special liquid fertilizer for orchids diluted 2000 times is added once a month. Light and temperature management Receive full sunshine in spring and winter, and shade 70%-80% in summer. Maintaining the temperature difference between day and night of 8-10℃ is conducive to flower bud differentiation, and the winter maintenance temperature should not be lower than 5℃. Use a rotating tray to adjust the light receiving direction by 180° every week to ensure a symmetrical plant type. Pest and pest control regularly wipe the leaves with garlic extract to prevent scale insects.(T-J) At the beginning of the disease, spray 50% carbendazim with 800 times solution. When replacing the substrate every spring, soak the roots in 1000 times potassium permanganate solution for 20 minutes for disinfection.
By mastering these potted orchid planting and maintenance techniques, and regularly observing the plant condition, you can cultivate high-quality orchids with bright leaves and blooming year after year. It is recommended to establish a maintenance log to record the water and fertilizer management time, and through 3-5 years of practical accumulation, gradually form a cultivation system suitable for your own environment.
