These orchids must undergo vernalization before they can blossom.

Vernalization is a process of low temperature flowering that many hardy flowers must undergo. Orchids such as Cymbidium and Cymbidium need to undergo continuous low temperature treatment for a period of time in order to promote their flower bud differentiation, otherwise they can not breed buds. Many people find that their potted orchids can not blossom all the time, it is likely that your orchid varieties need vernalization, but you do not know, or do not know how to deal with it.

The vernalization of different varieties of orchids have different requirements on temperature. For example, orchids such as Cymbidium, Jian Orchid and Cold Orchid can blossom naturally without special low temperature vernalization. Cymbidium and Cymbidium and other orchids must undergo low temperature vernalization treatment. Of course, it does not mean that orchids that do not need vernalization do not need temperature control, just like orchids whose temperature is too low and too high are easy to collapse. It will also cause it not to blossom, or even if it does, it is not ideal.

The main purpose of vernalization is to enable orchids with buds to get a certain process of dormancy and nutrient storage, and to facilitate the growth and flowering of non-budding orchids through vernalization and dormancy, so when is it better to vernalize potted orchids? how can vernalization be carried out to make it bloom? Let's take Chunlan as an example to take a look at the vernalization methods and precautions of Chunlan:

1. Vernalization time of Chunlan

The ideal temperature for vernalization is between 4-10 degrees. Potted orchids in the north are usually about 3-4 cm unearthed from the bud of spring orchids. When the bud stops growing tall and the development is slightly round, let the potted plants be in an environment of 4-10 degrees. Vernalization can begin.

2. The vernalization time of Chunlan

Generally speaking, the longer the vernalization time, the better. It usually takes 30-40 days for Chunlan vernalization, 40-50 days for Chunjian lotus petal, and more than two months for Cymbidium and spring delivery.

3. Matters needing attention during vernalization

The humidity of orchid potted plants during vernalization should not be too high, so we should pay attention to water control and dry conservation as far as possible, otherwise it is easy to cause rotten roots or rotten buds. In addition, in order to accumulate nutrients to make flowers bright after vernalization, foliar fertilizer should be sprayed before vernalization. After the vernalization period, water thoroughly (pay attention to avoid buds), and then put the orchid potted plants in an environment of about 15 degrees and then move indoors to avoid sudden heating caused by hot buds or buds phenomenon.

All right, these are the methods and precautions of vernalization of orchids. Friends who raise orchids but find out that orchids can't bloom can pay attention to whether your orchid potted plants have been vernalized, and have you done all the things you need to pay attention to when vernalization?
