What if the goldfish orchid leaves turn yellow?

Goldfish hanging orchid is also known as goldfish flower, hanging goldfish, kangaroo flower and so on. Goldfish Cymbidium is a perennial herb of the genus Gesneriaceae, with a semi-woody base. Goldfish hanging orchid leaves are dark green, thick leaves, small mouth, big belly, orange appearance, very much like a small goldfish, so it is called goldfish hanging orchid.

Goldfish hanging orchids like high temperature, high humidity, negative environment. The suitable temperature for the growth of goldfish hanging orchid is 18mur22 degrees Celsius, avoid low temperature. Once the growth temperature of the goldfish orchid is lower than 10 degrees Celsius, the leaves will begin to turn yellow. in the summer high temperature, the growth of the goldfish orchid is very slow, and the leaves will fall when the temperature exceeds 30 degrees Celsius.

What are the reasons for goldfish hanging orchid leaves yellowing? The phenomenon of leaf yellowing in the growth process of goldfish is caused by a variety of reasons:

1. The light is too strong

Goldfish orchids like the semi-shady environment, if the light is too good, it will affect the growth of goldfish orchids, the leaves will turn yellow.

2. Lack of light

Although the orchid is a semi-negative flower, at least four hours of astigmatism should be seen every day, otherwise the chlorophyll will decrease and the leaves will turn yellow.

3. The temperature is too low

The best growth temperature of goldfish orchid is 18 ℃-22 ℃. If the temperature is too high, the growth of goldfish orchid will be very slow or almost stop, so proper shading measures should be taken to make it grow exuberantly without defoliation. If the temperature is below 10 ℃ for two consecutive days, the leaves begin to turn yellow and dry until they fall off with the slightest vibration.

4. stagnant water in the basin

Goldfish orchid basin is not allowed to accumulate water, if the basin soil is not dry for a long time, root breathing difficulties, resulting in leaves yellowing. The soil should be loosened and moisture should be controlled in time.

5. Watertight for a long time

If it is not watered enough, it will cause the goldfish hanging orchid root to lose water, and the lower old leaves turn yellow. It should be watered thoroughly to keep the basin soil warm and moist.

6. Excessive fertilization

Too much fertilizer exceeds the demand of the plant. At the beginning, the leaves were shiny and uneven, the roots rotted and the leaves were yellow. It is also what we often call over-nutrition, burning to death. Should stop fertilizing, irrigate more water, or turn the pot to clean the root, renew and change the soil.

7. The basin has not been turned over for a long time.

The various nutrient elements contained in the basin soil have been exhausted, the three elements of nitrogen, phosphorus and potassium have not been replenished in time, the plant is lack of nutrients, and the leaves are yellow and thin. Fertile soil and fertile water should be replaced in time.

Note:

1. Goldfish hanging orchid is sensitive to light and cannot be directed directly, so it can accept appropriate irradiation when the sun is not strong in winter.

2. When the goldfish hanging orchid is short of water, it will also cause defoliation, or make the leaves brown, affecting the beauty, so it should be watered in time.

3. When the climate is dry in summer and autumn, it is necessary to spray water to increase the air humidity around the plant, otherwise too dry may cause scorch at the top or edge of the leaf.

4. do not apply fertilizer during the flowering period of goldfish orchid.

5. Pruning and shaping should be carried out after the flowers fade.

Goldfish hanging orchid like high temperature, high humidity, negative environment, afraid of high temperature, not cold-resistant, like the partial acid soil with good drainage permeability. Only by mastering the growth habits of goldfish orchids can we do a good job of maintenance and management, so as to avoid the occurrence of yellowing of leaves or leaves.
