Whether the orchid can be fertilized after the flower arrow has just grown should be judged according to the state of the plant.If the plant is in good condition, the leaves are shiny and the rhizomes are strong, it means that it has accumulated enough nutrients to meet the needs of flowering.In this case, you don't need to fertilize it.But if the plant is not in good condition, the leaves are thin and the buds are thin, then it means that its condition is not very good.In this case, a small amount of phosphorus and potassium fertilizer should be applied to stimulate it to blossom.
Whether the orchid in the flower bud stage needs fertilization should also be judged according to the state of the plant.If it has been fertilized before it grows buds, it is in good condition and the buds are relatively large, then there is no need to fertilize, so as not to damage its root system.But if the bud of the plant is thin and weak, or even the leaves turn yellow because of lack of nutrition, it should be supplemented with some fertilizer to provide nutrition.
Generally, it is not recommended to fertilize the orchid when it is blooming.Because fertilizer is applied at the time of flowering, it is easy to stimulate its root system and make it wither in advance.In addition, if the fertilizer is accidentally splashed on the flowers, it will also cause the flowers to wither ahead of time.So when the orchid is blooming, it is better not to fertilize it.
