When will Phalaenopsis orchids bloom after growing aerial roots
After Phalaenopsis orchids grow aerial roots, they will develop flower spikes during the autumn and winter seasons. The easiest season to grow flower spikes is in autumn and winter when the light intensity is not high, preventing the plant from getting burnt, and the temperature difference between day and night is around 5-8 degrees Celsius, which allows for quick formation of flower buds. Proper water and fertilizer management will soon result in the growth of flower spikes.
1. -- Autumn and Winter --
After Phalaenopsis orchids grow aerial roots, they generally develop flower spikes in the autumn and winter seasons. This plant starts to grow flower spikes three months before the flowers bloom, naturally occurring during the Spring Festival. However, with artificial care, it can start earlier by managing light, temperature difference, and water and fertilizer.
2. -- Light Management --
If Phalaenopsis orchids want to grow flower spikes, light management is essential. Starting from early autumn, the light intensity decreases, but the plant itself is not tolerant to strong light exposure. Therefore, it is still necessary to provide some shading at noon, allowing the plant to receive light only in the morning and afternoon. After late autumn, shading is no longer needed.
3. -- Temperature Management --
For Phalaenopsis orchids to produce flower spikes, temperature adjustment is necessary, not only to keep the plant in a comfortable and stable environment but also to ensure that the daytime temperature is around 20-22 degrees Celsius, and the nighttime temperature is around 15 degrees Celsius, with a temperature difference of 5-8 degrees Celsius to stimulate the plant to grow flower spikes.
4. -- Water and Fertilizer Management --
If Phalaenopsis orchids want to grow flower spikes, they also need sufficient water and fertilizer (G-Y), ensuring they have plenty of water and nutrients for consumption. When watering, it is essential to water thoroughly and ensure the soil is dry before watering again, without any waterlogging. Fertilizing should focus on phosphorus and potassium fertilizers, using less nitrogen fertilizer, avoiding raw fertilizers, and applying thin and frequent fertilization.
