Why do orchids not bloom?
As a representative of elegant flowers, orchids are troubled by the problem of flowering. This article analyzes the three core elements and combines 20 years of gardening experience to systematically sort out all solutions from environmental regulation to daily maintenance, so that your orchids bloom as scheduled. Analysis of the core factors of orchids not blooming improper environmental control 1. Light management: Orchids need to scatter light for 4-6 hours a day, and can accept direct morning light in spring and autumn. Long-term shading can lead to insufficient photosynthesis. It is recommended to use a luminometer to monitor the light intensity and maintain it at 8,000 - 12,000 lux.
2. Temperature and humidity control: The temperature difference between day and night should be maintained at 8-10℃ (22-25℃ during the day and 14-16℃ at night), and the air humidity is optimal at 60%-70%. It is recommended to configure a temperature and humidity meter to be used with a humidifier and ventilation system. Temperature difference stimulation is less than 1. Principle of vernalization: Most orchids need to undergo about 30 days of low-temperature vernalization (10-15℃), which is the key to flower bud differentiation. It can simulate natural seasonal changes and gradually reduce night temperatures in autumn.
2. Temperature difference management: Temperature differences are created 45 days before flowering. It is recommended to use intelligent temperature control equipment to maintain a periodic change of 22℃ during the day/15℃ at night. Imbalanced water management 1. Watering cycle: Adopt the "three-look principle"-look at the plant material (the surface is white), look at the root system (silver white), and look at the season (half in winter). It is recommended to use a transparent pot to observe root conditions.
2. Spraying skills: Equipped with a fine mist spray can, foliar water replenishment avoids noon. You can add 0.1% potassium dihydrogen phosphate for foliar topdressing.
By systematically regulating the light cycle, accurately controlling temperature and humidity fluctuations, establishing a scientific water supply system, and supplementing phosphorus and potassium fertilizers (twice a month before flowering), obvious flower bud differentiation can be seen within 3 months. It is recommended to establish a maintenance log to record changes in key parameters and gradually grasp the flowering rules of orchids.
