When is Phalaenopsis open?
Known as the "Queen of Orchid", Phalaenopsis has become a popular choice for home green plants due to its elegant flower appearance and long flowering period. For this butterfly-shaped epiphytic orchid, flowering control is a core issue in the conservation process. Mastering its opening rules and maintenance skills can keep the fluttering flower shadows in the hall. Natural flowering rules of Phalaenopsis The main characteristics of flowering period In the natural environment, Phalaenopsis usually reveal its beauty in early April and continue to bloom for 2-3 months. Modern gardening technology can extend the flowering period to August through environmental control, creating a flower feast that lasts for five months. Each plant can produce 2-3 flower arrows and carry 8-12 flowers in a single branch, forming a beautiful arched inflorescence. Environmental factors influence mechanism The temperature difference between day and night is the key to triggering flower bud differentiation. The ideal temperature difference should be maintained at 8-10℃. The light intensity needs to be controlled at 10,000 - 15,000 lux. Too strong will cause leaf burns, and too weak will affect flower bud formation. Maintaining the air humidity at 60-70% is most conducive to the extraction of flower arrows. Maintenance skills to extend flowering period. Maintaining a constant temperature of 18-25℃ during flowering period can extend viewing time by 2-3 weeks. Use scattered light source, and the daily light duration is not less than 12 hours. Apply liquid fertilizer with a ratio of phosphorus and potassium of 3:1, and supplement 500 times diluent every 10 days. The substrate is kept in a slightly moist state, and the immersion water supply method is used to avoid accumulated water. Pruning and maintenance at flowering stage timely removal of residual flowers can save 30% of nutrient consumption. Three bud points should be reserved at the pruning position 2 cm away from the base. Combined application of brassinolide can activate dormant buds and promote secondary arrow extraction. Be careful to keep the trimming tools disinfected to avoid wound infection. Technical points for secondary flowering control of Phalaenopsis in greenhouse and multi-flowering professional greenhouses simulate the alpine climate and implement temperature difference stimulation between day and night for 2 months after flowering: 28℃ during the day/18℃ at night for 3 weeks, combined with 200ppm gibberellin treatment, it can achieve Anniversary flowering. Home maintenance can create a small environment by enclosing a balcony, and the success rate can reach more than 60%. Home maintenance and re-flowering plan Keep healthy flower stems after flowering and prune 3-4 sections, and place them on the north-facing sill to receive morning light. Apply organic fertilizer containing humic acid every month, combined with foliar spraying potassium dihydrogen phosphate. By maintaining the ratio of 7:3 of pine bark and water moss in the substrate, new flower buds can germinate after 3 months.
Mastering the biological clock laws of Phalaenopsis and combining scientific maintenance methods can not only extend the single flowering period, but also achieve anniversary viewing. From temperature control to nutrient management, every detail is related to the blooming duration of this air dancer. By creating a suitable growth microenvironment, the elegant figure of Phalaenopsis can be used to decorate the living space for a long time.
