Reasons Why Orchid Leaves Grow Luxuriantly but Do Not Bloom, and How to Choose Fertilizer for Phalaenopsis

Many people have grown Phalaenopsis. Some grow them very well and can even reuse the same plants bought the previous year the next year, while others find that as they grow them, the plants only put out leaves like crazy but never bloom. What exactly is going on?

As for the above problem, it is actually caused by several factors. First, it may be that the flowering period has not yet arrived. Orchids bloom according to their own rhythm, so you need a bit of patience. Especially for newly cultivated seedlings, they need to be grown for at least 2 to 3 years, and once the seedlings grow into mature plants, they will bloom.

Secondly, it may also be a problem with care. For example, insufficient light, because to form flower buds it needs plenty of light. If it is kept in too dark a place for a long time, it cannot carry out photosynthesis properly, so it will naturally be difficult for it to bloom. In addition, provide appropriate shade in summer to avoid being burned by ultraviolet rays.

There is also the matter of watering. Some people are too diligent and water too frequently, so the pot is always wet and the roots stay soaked in water, which easily causes root rot, and this will also affect its blooming. It is recommended to follow the principle of watering when dry and not watering when not dry. If there is a lot of rainy weather in April, reduce the frequency of watering appropriately. In winter, when it enters the dormant period, watering should also be paused to avoid root rot affecting the plant.

Then there is also the factor of incorrect fertilizing. Using too much fertilizer, or using the wrong type, may also result in it only growing leaves vigorously while having no inclination to bloom. It is recommended that during the growing season, you can apply a fertilizer that contains both phosphorus and potassium, which can promote better blooming.

Finally, it may be that the day-night temperature difference is too small, because a small temperature difference will affect the growth of flower buds. Here it is recommended that the temperature difference is best above 10°C. Varieties that are more tolerant of light can be grown outdoors, while those not tolerant of light can be placed indoors to receive scattered light.

Another possible reason is that when the orchid is planted, it is buried too deep, covering all the roots that normally need to breathe. This will affect the absorption of nutrients and water in all aspects, and at this time the plant will only grow leaves and not flowers. It is recommended that when planting, the soil only needs to cover up to the base of the stem.
