What is the reason why the flower neck of a gentleman's orchid blossoms very short?
This seems to be a "clip arrow" phenomenon. There are generally two reasons, one is the lack of fertilizer and water, and the lack of enough water in the basin soil. Nutrients, the flower stem is unable to extract. The other is that the environmental temperature is not enough. The best temperature for flower stem extraction is 20-30 degrees. The solution is to fully fertilize before flowering, especially phosphorus and potassium fertilizer. If the temperature is low, it can be heated at the bottom of the basin.
