Why do orchid buds wither and turn black?

There are many varieties of orchids. There are five major varieties of orchids in my country. The most common ones are orchids with small white flowers. Only healthy flower buds can produce full flowers. So why do orchid buds wither and turn black?

Why do orchid buds wither?

Orchids grown in places with compacted and acidic soil, barren land, severe drought, lack of water and fertilizer, strong exposure to sunlight, root damage and stunted growth, etc., will have insufficient nutrients and water, and the nutrients and water will evaporate as soon as the flower buds emerge, causing the orchid buds to wither as soon as they emerge.

Secondly, the rainfall and soil humidity are too high in the rainy season, which makes the roots suffocate in an airtight environment. The leaves absorb a lot of water and cannot evaporate it. The orchid has sufficient water in its body, and the orchid swells as a whole. The newly emerged buds are eroded by water, causing them to wither and fall off. This is not a problem caused by pests and diseases.

Why do orchid buds turn black?

Whether it is vernalization or vernalization, attention should be paid to the management of fertilizer, water, and light during the vegetative growth and reproductive growth. There are many reasons for the death of flower buds due to blackening, scorching and falling off, most of which are caused by excessive humidity, excessive fertilizers, insufficient ventilation and other reasons.

Generally, flower bud differentiation is enough to indicate sufficient nutrition, and there is no need to continue to add fertilizer, only leaf topdressing can be carried out. The so-called flowering period should pay attention to the management of fertilizer and water, promote the rapid expansion of flower buds, that is, pay attention to leaf topdressing. At the same time, during this period of high temperature, orchids are still growing, so as to strengthen sterilization and disinfection.

When budding, if you blindly fertilize and irrigate, coupled with occasional high temperature and stuffiness, instead of ventilation and other conditions, the bracts will turn black, scorch, fall off and die.

How to care for orchid buds in winter

1. Never fertilize orchids, because the fertilizer they need should be applied during the bud formation period. Even if it is late in the fertilization season, you can only apply granular fertilizer, and apply it away from the roots and buds. Granular fertilizer takes a process to dissolve and absorb, unlike liquid fertilizer, which is direct.

2. Get more sunlight (except for plain flowers) to increase the photosynthesis of orchid leaves and produce and store as much energy as possible.

3. At the beginning of the flower buds, spread a small amount of moss on the surface of the pot, and then gradually increase the amount of moss. Don't cover too much at one time. This can keep the flower buds warm in winter.
