Do spring orchids need vernalization when they have buds? (The best method and time for vernalization of orchids)

Do orchids need to be vernalized only after they have buds?

Vernalization of orchids is a very important step. If you want to produce high-quality orchids, low-temperature vernalization is a necessary step. This is a process of natural selection and cannot be replaced by other methods.

Especially for spring orchids, don't skip this step. If you want the orchid to emit fragrance, this step is necessary . And raising orchids itself requires more energy, but due to the cold weather in the northern region, vernalization is not required.

First of all, orchids only need vernalization after they have flower buds and are about to bloom. There is no need for vernalization for orchids without flower buds , and it is meaningless.

The purpose of vernalization is to keep the orchid in the reproductive growth stage, so that the flower buds have sufficient nutrients to bloom smoothly and make the orchid bloom more effectively.

Of course, not all orchids need vernalization. Vernalization is only for native orchid species such as spring orchid, cymbidium orchid, spring sword orchid, and lotus orchid in subtropical monsoon regions.

In addition, the process of vernalization is quite complicated. It does not mean that you have to wait until flower buds appear before vernalization . Below I will briefly share with you the process of vernalization of orchids.

Many flower lovers may not know what vernalization is. In fact, it is to let orchids go through a period of continuous low temperature before they can enter the reproductive growth period.

If orchids want to bloom well, they need to go through a long winter and severe humidity to produce high-quality flowers . If they are not stimulated by low temperatures, it is difficult for orchids to bloom well or even not bloom.

Time and temperature of vernalization of orchids

The time for vernalization of orchids is generally chosen when the orchid buds are about 3 cm out of the ground, and the vernalization period should last for about one month.

The temperature of vernalization needs to be controlled at around 2 to 5 degrees, not too low or too high. Practice has proved that this temperature is most suitable for vernalization of orchids, and the flowers that bloom are of the best quality. This temperature is most suitable for the accumulation of nutrients in the flower buds, and the flowers that bloom are particularly bright.

Auxiliary work for vernalization of orchids

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

For example, watering and temperature difference. During the period of vernalization, watering should be controlled and the amount of watering should be reduced. The temperature difference should be as large as possible. A large temperature difference between day and night can make orchids bloom better.

When watering, you can add a little rice vinegar and potassium dihydrogen phosphate to the water to improve the pH of the soil, increase acidity, and promote the growth of orchids.
