How long does it take for the spring orchid bud to undergo vernalization | At least not less than 70 days
Answering netizens' questions about the spring orchid, a member of the orchidaceae family, regarding how long the spring orchid bud needs to undergo vernalization | At least not less than 70 days, the details are as follows:
Seeing some orchid enthusiasts asking how long it takes for the spring orchid bud to bloom in spring, a vernalization period of 70-100 days is recommended, and it is best not to be less than 70 days. The longer the vernalization time, the better the quality of the flowers, but it should not be too long, otherwise, it will be like having a lot of strength but nowhere to use it.
About the issue of vernalization, the older generation has talked a lot about it, and it is all very meaningful for reference. I will share my experience in the process of practice (vernalization of spring orchids in the north):
First, choose strong seedlings with good genes. If the genes (source) are not good, even if they grow strong, they will not bloom well. Some orchid friends posted that the flowers are not good, and they plan to vernalize again next year. I want to say that if the genes (source) are not good, no matter how you vernalize, it will not be good. Next year will be another disappointment, but sometimes even with good genes, the flowers may not bloom well due to issues like vernalization. The pictures in the text all started vernalization on November 26, 2017.
Second, the duration of vernalization. A period of 70-100 days is recommended, and it is best not to be less than 70 days. The longer the vernalization time, the better the quality of the flowers, but it should not be too long, otherwise, it will be like having a lot of strength but nowhere to use it.
Third, the temperature for vernalization. It is best to choose a stepped降温 (temperature reduction) method for vernalization. I vernalize from 20-15-10-5 degrees. The temperature must not be too high; once the crystal head and autumn buds grow, the quality of the flowers will be affected.
Fourth, the timing of vernalization. I choose to start vernalization when the bud is 0.5-1 centimeters above the ground, excluding other factors. The choice of timing for vernalization and the light before vernalization are crucial to the brightness of the tongue spots.
Fifth, watering during vernalization. There are no fixed standards; just water when it's dry.
