How to raise the newly purchased Wenxinlan
Known as the "dancing orchid", Wenxin orchid is popular for its elegant flower appearance, but the maintenance of newly purchased plants requires special attention. This article will systematically explain the key points of cultivating Oncidium from the beginning to daily management, and help you easily create home orchid gardening. 1. Treatment specifications for initial purchase of Oncidium 1.1 Root inspection and disinfection Oncidium purchased in spring must be inspected immediately out of the box, focusing on observing root health. Use disinfectant scissors to trim black/rotten fleshy roots to retain strong white roots. Prepare 0.5% potassium permanganate solution and soak it for 30 minutes to effectively kill hidden bacteria. 1.2 Plant root drying techniques After disinfection, the disinfected plants should be laid flat in a cool and ventilated place to dry the roots, maintaining the ambient temperature of 18-25℃. Serve the pot when there are no obvious water stains on the surface of the root system (about 2-3 hours) to avoid secondary infection caused by excessive humidity. 2. Scientific Potting Steps for Oncidium 2.1 The selection standard recommends using a veg-fired pottery basin with a diameter of 15-20cm, and the number of ventilation holes should be ≥8. Purple sand pots need to ensure that the wall thickness of the pot is ≤1cm to avoid stagnant water causing root rot. 2.2 The substrate preparation plan adopts a gold ratio of water moss: pine bark: volcanic rock =4:3:3, and the pH value is controlled between 5.5 and 6.5. Before use, soak the substrate in boiling water for 30 minutes to sterilize, and dry until it is semi-dry. 3. Guidelines for systematic maintenance of Oncidium 3.1 Light control strategies Slow down seedling stage is placed on the east-facing sill to receive morning light, and the light intensity is maintained at 5,000 - 8,000 Lux. During the growing period, you can move to the north balcony, and use a sunshade net to filter the noon light to ensure scattered light for 3-4 hours a day. 3.2 Temperature and humidity management keeps the temperature difference between day and night between 5-8℃, the temperature during the day is 20-28℃, and the temperature at night is not lower than 15℃. Air humidity of 65%-75% is maintained through a humidifier, and foliar spraying needs to avoid noon. 3.3 The key points of water and fertilizer control are to adopt the "see dry, see wet" watering method, and water is poured thoroughly when the surface of the substrate is white. During the growth period, 2000 times of orchid special fertilizer with N-P-K=20-20-20 was applied every 15 days, and phosphorus and potassium fertilizer were applied before flowering.
Following the systematic maintenance method of this guide, the survival rate of newly purchased Oncidium can reach more than 90%. Regularly observe the condition of the leaves and adjust the maintenance details in time. After half a year, you can enjoy the dancing orchids.
