Cymbidium Summer Care
As one of China's top ten traditional famous flowers, Cymbidium faces the dual challenges of high temperature and humidity during the midsummer season. Mastering scientific summer care methods not only keeps the Cymbidium plants green and upright but also lays the foundation for the differentiation of flower buds in autumn. This article systematically sorts out six core management points to help flower enthusiasts build a complete Cymbidium summer care system.
I. Three Key Elements of Environmental Control
Temperature Control Strategy
When the temperature exceeds 32°C, Cymbidium enters a semi-dormant state. It is recommended to take double cooling measures: turn on the circulating fan from 9 am to 3 pm daily and place a water-holding tray under the Cymbidium shelves to lower the local temperature by 3-5°C using the principle of evaporative cooling.
Sunshade System Setup
Adopt a double-layer sunshade net combination plan: fix an outer layer of black sunshade net with 50% light shading and an inner layer of adjustable 30% silver net. Special attention should be paid to ensure complete coverage of the sunshade net during the west-facing period (2-5 pm) to prevent sunburn spots on the leaves.
Ventilation Management Norms
Keeping the air circulating should follow the 'three open and three close' principle: open the windows for 1 hour in the early morning, open the top window for 30 minutes at noon for convection, and ensure comprehensive ventilation for 2 hours in the evening. During the rainy season, use a dehumidifier to keep the humidity within the range of 65-75%.
II. Golden Rules of Water Management
Scientific Watering Schedule
Implement the segmented watering method: spray the leaves in the morning from 6-8 am, and complete the thorough watering of the substrate in the evening from 6-8 pm. Use the water temperature adjustment method, allowing the irrigation water to stand in advance to match the room temperature, to avoid excessive temperature differences that damage the roots.
Humidity Balancing Techniques
Hang a hygrometer between the Cymbidium shelves for real-time monitoring and use a 'curtain plus atomization' double humidification system. Start the atomization device when the humidity is below 60% and turn on the exhaust fan for dehumidification when it is above 80%, maintaining an ideal microclimate environment.
III. Disease and Pest Control System
Establish a three-level protection mechanism of 'prevention, monitoring, and treatment': alternate the use of carbendazim and mancozeb for preventive spraying every half month; lay a diatomite isolation layer on the surface of the planting material; immediately use a 75% alcohol cotton swab for physical removal if scale insects are found.
By precisely controlling temperature and humidity, constructing a scientific sunshade system, implementing standard water and fertilizer management, and complementing it with a strict disease and pest control network, the success rate of Cymbidium summer care can be significantly improved. It is recommended for flower enthusiasts to keep a care log, recording daily environmental parameters and management measures, and continuously optimize the care plan through data accumulation, allowing the Cymbidium plants to maintain vigorous vitality even in the midsummer heat.
