The best time for repotting and division vs. germination rate and rate of strong seedlings
It is almost the repotting season again, so I would like to offer a little trick of mine to all my fellow orchid-growing brothers and sisters, and welcome everyone to discuss my views.
We all know that repotting and division should be done in spring and autumn, yet no monograph states a best time, and none of the orchid experts do either.
As everyone knows,orchidsstill mainly rely on division for propagation, and of course everyone does this work in spring and autumn, but have you ever thought about one detail: the germination rate and the rate of strong seedlings differ noticeably between these two seasons. What I discuss here refers only to Jiangsu and ZhejiangCymbidium goeringiiand Cymbidium faberi. Have you not felt thatorchid plantsintroduced in autumn are much better in germination rate and rate of strong seedlings than those introduced in spring, and thatorchid plantsintroduced in the first and middle ten days of September are even better?
In my practice over these years, I believe repotting and division should begin in the first and middle ten days of September, because after the flower buds have formed, the orchid plant has basically matured and has returned to vegetative growth. At this time the new shoots have not yet formed, and precisely then repotting and division can stimulatethe orchid plantto quickly form new growth points within one month. At this time the temperature is still suitable, the orchid is still growing slowly, and by November the new shoots are already very large. After a winter's dormancy, by early spring it would be hard for these shoots not to be strong. On the contrary, when repotting in spring, the orchid has just awakened and then suffers the damage of repotting and division; it cannot avoid a recovery period of half a month to a month, and the growth points may also suffer accidental damage, so one can imagine these shoots are not as good as those from autumn repotting.
In addition, growth points from early-autumn repotting can emerge as early as February or March, and by the plum rain season they are already half-grown plants; in May and June stacked shoots will appear, and by August they are large plants again. So practice over these years has verified that this experience is quite correct. Today I offer this little trick to everyone, and I think it will be of some help to all my fellow orchid growers.
Remember, the best time for repotting and division is mid-September, and everyone need not worry that repotting the orchid a month early will affect the roots; in fact, doing it a month early not only has no effect on the orchid but brings many benefits for the coming year's growth. If anyone thinks there is anything inappropriate, please criticize and correct it, so that we can raiseorchidseven better tomorrow!!!
