How many days do the flowers of large-leaf cymbidium orchids generally bloom?
How many days large-leaf cymbidium orchids can bloom specifically depends on the management of the flowering period and temperature control. If temperature is not controlled and management is not emphasized, they can bloom for about 40 to 60 days; if the flowering period is managed properly, they can bloom for more than 100 days. During the flowering period, provide a temperature above 5°C and below 15°C, and usually place them in indirect light; do not expose them to direct sunlight. In addition, stop fertilizing, and just pay attention to ventilation and watering.
I. How many days can they bloom
How many days large-leaf cymbidium orchids can bloom specifically depends on the management of the flowering period and temperature control. If they are allowed to bloom naturally without temperature control, they will bloom for about 40 to 60 days; if the temperature is well controlled, the flowering period can last more than 100 days, and the flower colors will also be very vivid.
II. Methods to extend the flowering period
1. Lower the temperature: the suitable temperature for its growth is around 15°C, and above 20°C it will grow slowly or even stop growing. If it has already bloomed or is about to fully bloom, the temperature can be controlled above 5°C and below 15°C, so the flowers will open more slowly and the flower colors will also be vivid.
2. Reduce light: during the flowering period, it likes indirect light and cannot be exposed to direct sunlight. If there is direct sunlight, the flowers will fade early, and the leaf color will also become dull, reducing ornamental value. If it is given indirect light, the flowering period will naturally be extended, and the ornamental value will also be higher.
3. Stop fertilizing: its pseudobulbs are relatively thick and strong, and can store a large amount of nutrients and water, so there is no need to fertilize during the flowering period. Fertilizing at this time will instead cause the flowers to fade early. Usually, just pay attention to ventilation and watering.
