How to Care for Cymbidium Orchids During Blooming Period
The editor brings you the experience of caring for Cymbidium orchids during their blooming period and the detailed management methods for proper Cymbidium orchid care. Below is an introduction for you.
The blooming period of Cymbidium orchids is from June to October, which is from early summer to mid-autumn. They usually bloom twice, once in mid-July and once in mid-August. In the north, the blooming season is generally delayed, usually from July to November. Cymbidium orchids have high demands for soil nutrients during their blooming period, which coincides with the hot summer climate, so special attention should be paid to watering methods. Let's talk about the management methods for Cymbidium orchids during the blooming period.
1. Watering Method
Watering Cymbidium orchids during the blooming period should consider the ambient temperature and humidity. In the summer, water thoroughly every 3 to 5 days, pouring water along the edge of the pot until the soil is moist, preferably in the evening. Also, spray water on the soil surface every morning, and you can spray again at night when the temperature is high, and appropriately spray water or mist the plant surface to increase air humidity and clean the leaves.
In early autumn, which is the growing season for Cymbidium orchids, the soil should be kept moist, usually watering every 2 to 3 days. Also, ensure good soil drainage during the blooming period and avoid rain.
2. Fertilizing Method
Fertilize frequently with a light application of fertilizer. During the blooming period, the growth of Cymbidium orchid leaves slows down, so avoid applying nitrogen fertilizer. Before budding, mainly supplement phosphorus fertilizer, and apply foliar fertilizer once every 7 days. Stop fertilizing when the temperature exceeds 28°C and resume in the autumn when the weather cools down. In early autumn, apply phosphorus and potassium fertilizer.
3. Light and Ventilation Requirements
Cymbidium orchids enjoy light but do not tolerate strong sunlight. During the blooming period, keep them in a shaded environment with plenty of scattered light. In the summer, enhance ventilation and ensure good drainage of the potting soil to prevent diseases such as bacterial sheath blight and anthracnose.
4. Pest and Disease Control
Diseases and pests such as bacterial sheath blight, anthracnose, and scale insects are common during the blooming period. In a hot and humid environment, Cymbidium orchids are prone to scale insects, which can be controlled by spraying with a diluted solution of 40% omethoate or 50% malathion. If bacterial sheath blight is detected, immediately change the pot and sprinkle lime or pentachloronitrobenzene powder into the soil.
5. Repotting and Soil Change
After 1 to 2 years of growth, the root space of Cymbidium orchids becomes narrow, and the nutrients in the potting soil are depleted due to the energy consumed by blooming in the summer. It is usually necessary to repot every 1 to 2 years. Repotting should be done after blooming, which is October or November. In northern China, where Cymbidium orchids often sprout new buds in November, repotting is done at this time to avoid damaging the buds and because the climate is suitable for the plants to adapt to the new pot.
