Why Fertilizing During the Orchid Blooming Period Is Unsuitable and Points to Note

Some novice orchid growers, seeing that their orchids change very slowly during the bud stage, want to give them a little fertilizer, hoping they will grow a bit faster and better. In fact, orchids should not be fertilized during the blooming period. This is because when the flower buds begin to elongate, the plant's vegetative growth becomes relatively sluggish and enters a diapause stage.

At this point, if you continue to fertilize, especially with fertilizers high in nitrogen, it will stimulate vegetative growth and inhibit reproductive growth, resulting in poor flower bud development, petals that do not open fully, and early withering. Of course, if you do not need it to bloom, you can fertilize as usual.
