How long does the flower bud of Cymbidium take vernalization? try not to be less than 70 days.

When you see a flower friend ask how long the flower bud of Chunlan should be, the vernalization time should be 70 / 100 days, not less than 70 days as far as possible. The longer the vernalization time is, the better the flowering products will be, but not too long, otherwise, there will be no room for strength.

The elders have talked a lot about vernalization, all of which can be used for reference. I would like to talk about my experience in practice (vernalization of spring orchids in the north):

First, select strong seedlings with good genes (provenances). If the gene (provenance) is not good, no matter how strong it is, it will not open well. Lanyou posted that the opening product is not good, and it will be vernalization again the next year. I would like to say that if the gene (provenance) is not good, vernalization will not be good, and it will be sad the next year. But if the gene (provenance) is good, sometimes it is not good, it is vernalization and so on. In the pictures in the article, vernalization begins on November 26, 2017.

Second, the length of vernalization. It is appropriate to take 70-100 days, not less than 70 days as far as possible, the longer the vernalization time, the better the opening, but not too long, otherwise, there will be no use of strength.

Third, vernalization temperature. Try to choose a step-by-step cooling way to vernalization. I am vernalized by 20 murmurs. 5 degrees. The temperature must not be too high. Once the crystal head and autumn buds grow, the opening products will be affected.

Fourth, the timing of vernalization. I choose the bud unearthed about 0.5-1 cm to begin vernalization, excluding other factors, the timing of vernalization and the light before vernalization, the bright degree of tongue spots to Guanzhong.

Fifth, vernalization watering. There is no fixed standard, so water it when it's dry.
