Does the春兰 (Cymbidium) need to undergo vernalization when the flower buds appear? Do the flower buds of Cymbidium require vernalization?

Does Spring Orchid Need Vernalization After Flower Buds Appear?

The editor will explain the related green plant content of whether Spring Orchid needs vernalization after flower buds appear. Let's take a look together.

Does Spring Orchid Need Vernalization After Flower Buds Appear?

The process of vernalization is complex and does not mean that vernalization is only needed after flower buds appear. Simply put, it is to let the orchid experience a period of continuous low temperatures to transition into the reproductive growth stage. For the orchid to bloom well, it needs to go through a long winter and severe cold to produce high-quality flowers. Without the stimulation of low temperatures, it is difficult for orchids to bloom well or may not bloom at all.

Is Vernalization Necessary Only When the Orchid Has Flower Buds?

Vernalization is an important step in producing high-quality orchids. Low-temperature vernalization is a necessary step, which is a process of natural selection and cannot be replaced by other methods.

Especially for Spring Orchid and Huilan, this step should not be skipped. If you want the orchid to emit fragrance, this step is essential. Moreover, caring for orchids itself requires a lot of effort. However, in the northern regions, due to the cold weather, vernalization is not needed.

Once, after the orchid has flower buds, vernalization is only needed during the period of stem elongation and flowering. There is no need for vernalization if there are no flower buds, as it is meaningless.

The purpose of vernalization is to keep the orchid in the reproductive growth stage, allowing the flower buds to have sufficient nutrients to bloom smoothly and make the orchid's flowers more presentable.

Of course, not all orchids need to go through vernalization. Vernalization is only for native orchid species such as Spring Orchid, Huilan, Spring Sword, and莲瓣兰 (Lianban Orchid) in subtropical monsoon regions.

Additionally, the process of vernalization is complex and does not mean that vernalization is only needed after flower buds appear. I will briefly share the process of orchid vernalization with you below.

The concept of vernalization may be unfamiliar to many orchid enthusiasts. Simply put, it is to let the orchid experience a period of continuous low temperatures to transition into the reproductive growth stage.

If the orchid wants to bloom well, it needs to go through a long winter and severe cold to produce high-quality flowers. Without the stimulation of low temperatures, it is difficult for orchids to bloom well or may not bloom at all.

The Time and Temperature for Orchid Vernalization

The vernalization time for orchids is generally chosen when the orchid sprouts or the flower buds emerge about 3 centimeters from the ground, and the vernalization period should last for about a month.

The temperature for vernalization needs to be controlled between 2 to 5 degrees Celsius, not too low or too high. Practice has proven that this temperature is the most suitable for orchid vernalization, producing the best quality flowers. This temperature is most suitable for the accumulation of nutrients in the flower buds, making the flowers especially vibrant.

Supplementary Work for Orchid Vernalization

Vernalization is not just about low-temperature stimulation; it also requires appropriate improvements in maintenance management.

For example, watering and temperature difference should be controlled during the vernalization period, reducing the amount of water. The temperature difference should be as large as possible, with a significant difference between day and night to make the orchid bloom better.

When watering, you can add a little rice vinegar and potassium dihydrogen phosphate to the water to improve the soil's acidity and alkalinity, increase acidity, and promote orchid growth.
