Qiulan is also called Jianlan. Under normal circumstances, a potted plant of Qiulan (that is, more than 20 seedlings per pot) can germinate 2 to 3 times from early summer to late autumn, and the most vigorous flowering time is Before and after the fall, although the flower buds can be repeated after the autumn, the germination rate is significantly reduced. Since the flowering season is just the hottest day, the flowering period is short and the best flower viewing period is only 3 to 5 days. If the flowering period is pushed back, the temperature will drop a little, and the flowering period will certainly be extended accordingly.
I have planted orchids for more than 10 years and have many pots of autumn orchids. In recent years, I have taken the method of removing the flower buds that were germinated in the early (June to July) to delay the flowering period, and the effect is good. Specific practice: Take the end of July as the boundary, remove all the flower buds that have sprouted before the big pot of Qiulan (more than 20 seedlings), and then release the flower buds, so that it will be a full bloom in September, and the autumn will be pleasant and enjoyable. Relatively extended.
It should be noted that Qiulan must reach a certain number of seedlings. If the number of seedlings is small (below 10 seedlings), the flower bud rate is very low; only the number of seedlings is high (15-20 seedlings or more), and the flower bud rate is higher. Therefore, this measure is best implemented only on a large number of conjoined large pots of Qiulan.
