How to raise perfume dendrobium
As a treasure among orchid plants, Dendrobium pergoldii is favored by gardening enthusiasts for its elegant flower appearance and unique aroma. If you want this plant, which has both ornamental and medicinal values, to grow healthily, you need to master professional maintenance skills. This paper will comprehensively analyze the key points of Dendrobium cultivation from light regulation to overwintering management. 1. Light management plan 1.1 Creating perfume in scattered light environment Dendrobium orchid belongs to a typical epiphytic orchid type, and its original environment is the canopy of tropical rainforest. It is recommended to use a sunshade net with a shading rate of 40-60% to ensure 4-6 hours of morning light every day. In summer, special attention should be paid to shade protection during the noon period (11:00-15:00). You can use double sunshade nets or move to the north-facing balcony. 1.2 Application of fill light technology When there is insufficient light in winter, LED plant fill light (spectrum 400-700nm) can be used to replenish light for 2-3 hours a day. Pay attention to keeping a distance of more than 30cm between the lamp and the plant to avoid light burns. It is recommended to arrange the fill light period between 9 and 11 a.m. to simulate the natural light cycle. 2. Temperature control system 2.1 The temperature difference between day and night regulates the ideal growth temperature of 18-25℃ during the day/13-18℃ at night. Controlling the temperature difference between day and night at 5-8℃ is most conducive to flower bud differentiation. Natural temperature difference adjustment can be achieved by opening windows for ventilation in spring and autumn, and a water curtain cooling system is recommended when high temperatures in summer. 2.2 Although overwintering protection measures can temporarily tolerate low temperatures of-2℃, long-term temperatures below 5℃ will cause frostbite of cells. In the northern region, it is recommended to move indoors in late October and use a combination of foam boxes + heating pads to maintain the substrate temperature ≥8℃. It can be used with PE insulation film to build a miniature greenhouse. 3. Water management plan 3.1 Scientific watering cycles adopt the principle of "seeing dry, seeing wet". Water twice a week in spring and autumn (Tuesday/Friday), and increase to 3 times in summer (Monday/Wednesday/Friday). It is recommended to use rainwater or RO pure water. The water temperature should be consistent with the ambient temperature to avoid stimulating the root system due to temperature difference. 3.2 For substrate drainage optimization, a mixed substrate of pine bark (particle size 1-1.5cm): volcanic rock: moss =5:3:2 is recommended. A ceramsite drainage layer of 3cm thickness shall be arranged at the bottom of the pot, and the root control pot with the number of ventilation holes ≥8 shall be matched. After watering, tilt the pot at 45 degrees to drain excess water.
Through precise light and warm water control, combined with regular fertilization (it is recommended to apply a special slow-release fertilizer for orchids every month), the fragrant dendrobium can achieve the ornamental effect of blooming 2-3 times a year. It is recommended to change the pots every two years in the spring to plant in time to ensure plant vitality. By mastering these key technical points, you can also cultivate high-quality dendrobium with rich aroma and swaying branches.
