What is the reason for the drying of Phalaenopsis buds? How to solve the drying of Phalaenopsis buds?

With the improvement of living standards, more and more people like to grow flowers and plants at home. Phalaenopsis is loved by many flower growers because of its bright flowers. However, many people have encountered the problem of drying up buds during maintenance. Let’s take a look at how to prevent the buds from drying up when growing Phalaenopsis.

What causes Phalaenopsis flower buds to dry up?

1. It usually takes about 2 months for the orchid to bloom without air circulation. During this period, the orchid will grow flower buds, and it is winter in the north. The cold weather outside is getting worse, often accompanied by strong winds. If you do not pay attention to indoor ventilation, the orchid will be in this environment for a long time, and the buds on the top of the flower stems will wither and die.

2. Attacked by cold wind. If you open the windows for ventilation in winter and there is strong wind outside, the window will only be opened a little, which will blow directly towards the flower buds, causing the local temperature to be too low, which can easily cause the buds to fall.

3. The indoor air is dry. Phalaenopsis prefers a high temperature and high humidity environment. The heating environment in the north can easily cause the indoor humidity to be too low, causing the buds to dry out and fall off;

4. The indoor temperature is too low and the watering is excessive, and the pot is too wet. Phalaenopsis likes a high temperature and high humidity environment. But high temperature and high humidity are twin brothers and cannot be separated. Simply high temperature or high humidity will cause abnormal growth of flower buds, withering and falling buds;

5. The indoor temperature is too high or too low. The suitable temperature for Phalaenopsis flowers is 20-28℃. If the night temperature is lower than 15℃ or the daytime temperature is higher than 30℃, the flower buds will be poorly developed or stop growing.

6. Too much or too little light. Phalaenopsis orchids have different light requirements depending on their species. Appropriate light can promote the growth of flower buds, while too much or too little light will lead to poor development of flower buds.

7. Avoid applying too much fertilizer during the flowering period. Apply thin fertilizers frequently during the flowering period. Applying too much fertilizer too frequently during the flowering period can easily cause bud drop;

8. Accidental injury: Flowers are the reproductive organs of plants and are relatively delicate. Accidental bumps can cause buds to be injured, thus affecting their development and causing them to wither and fall off.

9. Pests and diseases. During the growth period of flower buds, they are more susceptible to attacks by pests and diseases, which disrupt their growth, affect nutrient accumulation, and are also the cause of falling flowers and buds.

How to solve the problem of dried Phalaenopsis flower buds

1. Curing temperature

The growth environment suitable for Phalaenopsis is high temperature and high humidity. If you want the Phalaenopsis to grow well at home, the minimum temperature should be kept above 15 degrees Celsius. The suitable growth temperature for Phalaenopsis is between 15 and 30 degrees Celsius. In summer, the weather is hot, so pay attention to ventilating the Phalaenopsis. In winter, you can keep the Phalaenopsis indoors to prevent frostbite.

2. Daily watering

Watering is an essential part of growing Phalaenopsis. Since Phalaenopsis does not have thicker leaves and stems, it does not have a lot of water in its body. You should pay attention to watering the Phalaenopsis regularly. If you accidentally let it lack water, the stems and leaves will easily become weak and lifeless.

When the stems and leaves are just growing out, you need to water the Phalaenopsis frequently. In summer, you can water it once in the morning and once in the evening. It is not suitable to water the plant at noon. In winter, the Phalaenopsis enters a semi-dormant state, so you need to reduce the number of waterings to about once a week.

3. Reasonable fertilization

The best time to fertilize Phalaenopsis is in autumn. At this time, you should fertilize Phalaenopsis several times to help the stems and branches grow stronger. When fertilizing Phalaenopsis, you must pay attention to it. When Phalaenopsis begins to differentiate flower buds, it is best to stop fertilizing to prevent fewer flowers next year. When Phalaenopsis grows flower buds, you should not fertilize it, otherwise the buds will fall off, affecting normal flowering.

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.
