Do I need to fertilize orchids when they have just formed flower arrows? Do I need to fertilize orchids after they have formed flower buds?

1. Should orchids be fertilized when they first flower?

Whether or not to fertilize the orchid after it has just grown flower arrows should be judged based on the condition 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, there is no need to fertilize it. But if the plant is not in good condition, the leaves are thin and the flower buds are weak, then it means that its condition is not very good. In this case, you should apply a small amount of phosphorus and potassium fertilizers to stimulate it to bloom.

2. Do you need to fertilize orchids after they grow buds?

Whether orchids in the bud stage need to be fertilized should also be judged based on the condition of the plant. If you have fertilized it before it grows flower buds, and it is in good condition and the flower buds are relatively large, then you don't need to fertilize it to avoid damaging its root system. However, if the flower buds of the plant are weak, or even some leaves turn yellow due to lack of nutrition, you should add some fertilizer to provide it with nutrition.

3. Do you need to fertilize orchids when they bloom?

Generally, it is not recommended to fertilize orchids when they are in bloom. Because applying fertilizer during flowering can easily stimulate its root system and cause it to bloom prematurely. In addition, if fertilizer is accidentally splashed onto the flowers, it will cause the flowers to wither prematurely. Therefore, it is best not to fertilize orchids when they are in bloom.
