Can I fertilize Phalaenopsis when it is blooming? How to fertilize Phalaenopsis?

Phalaenopsis is loved by many flower growers for its gorgeous flowers and rich fragrance. However, many novices make mistakes in fertilizing when growing it, which causes the newly bought Phalaenopsis to wither and die within a few days. So how should Phalaenopsis be fertilized? Let's take a look.

Can I fertilize Phalaenopsis when it is blooming?

Before Phalaenopsis enters the flowering period, you can apply some diluted phosphorus and potassium fertilizers to it, which is beneficial for its flowering. However, after it blooms, you don't need to fertilize it. Because it has accumulated enough nutrients when it blooms, it does not need additional nutrient support at this time. If you rashly fertilize it, it may cause damage to its root system and cause it to wither prematurely.

How to fertilize Phalaenopsis

During the growth period of Phalaenopsis, low-concentration water and fertilizer should be applied, and thin fertilizers should be applied frequently. Stop fertilizing when the temperature is above 32℃ or below 15℃.

Before July, root fertilizer and foliar topdressing should be applied alternately. Apply a general compound fertilizer of nitrogen: phosphorus: potassium (1:1:1) once and dilute it into 2000 times liquid for proper root irrigation.

Apply liquid fertilizer every 15 days in August;

After September, apply 0.1% potassium dihydrogen phosphate solution as foliar fertilizer;

After October, it is necessary to control water and fertilizer to promote the formation of flower buds. During this period, foliar fertilizers should mainly be root phosphorus and potassium fertilizers, and micro-fertilizers (boron, iron, zinc, etc.) should be applied appropriately.

Can I spray potassium dihydrogen phosphate after Phalaenopsis has flower buds?

When applying potassium dihydrogen phosphate fertilizer to flowers, try to apply it before the flower buds appear, that is, before the critical period of reproductive growth ends. It has a certain effect on promoting flower bud differentiation, promoting flowering and fruiting, and prolonging the flowering period. For Phalaenopsis, potassium dihydrogen phosphate can also be used after the flower buds appear. Although it is a little late, it can still play a role.
