Orchid planting techniques

A. Soil selection for orchids

Before using orchid soil, measure and adjust its pH level. If the soil is too acidic, lime can be added to adjust it. If the soil is too alkaline, sulfur powder, calcium superphosphate, ferrous sulfate, etc. should be mixed into the soil. Make the soil pH to neutral slightly acidic, pH between 5.5-7.0. Organic fertilizers, such as composted grass and leaves, can also be used. Add to the soil to change the pH of the soil.

B. Before planting orchids

The soil should also sieved and graded so that large, medium and small grains are separated. When planting, put the large grains at the bottom of the pot to facilitate drainage. It is also necessary to adjust the dryness and humidity of the soil, not too wet and not too dry. When you squeeze the soil in your hand, the soil can form a ball. And when the hand is loosened, the soil can scattered into particles, which means the dryness and humidity of the culture soil is suitable.

C. Temperature of orchids

Temperature is also an important item in the skill of orchid cultivation. Generally speaking, most of the orchids are grown in the forest or coastal areas where the air humidity is high. Therefore, they are not too adaptable to the dryness of the air.

1. Too low humidity of orchids

This will cause water loss inside the orchid plant, but it cannot replenished by the orchid roots, so it will cause the epidermis of the stems and leaves to crumple.

2. Spraying the orchid plant with moisture

Sprinkling water around the plant is enough to increase the humidity in the air, and it can also achieve the effect of cooling down the temperature.

3. Low air humidity

If the air humidity is low, the orchid leaves will be rough and lusterless. If the air humidity is suitable, the orchid leaves will be broad and shiny. This is the best basis to identify whether the air humidity is suitable for the growth of orchids.

D. Orchid watering

Watering orchids has a great deal of knowledge, and it is difficult to learn it all at once. You need to understand the physiology of orchids and have many practical experiences before you can understand the key points. The following factors should taken into consideration when managing water: season, sunlight, temperature, humidity, orchid pots, substrate, orchid plants and environment, etc.

1. Comprehensive factors

The factors that determine how long an orchid can watered at a time vary from time to time and from place to place. It is very complicated, so we can only make appropriate watering based on practical experience and understanding of orchid physiology.

2. It is said in the Quran

“There is no certain method for irrigation”, which is reasonable. Only by long-term observation can we properly manage water. In spite of this, the following are common problems and more mature experiences after long practice by previous generations.

3. Water for orchids

Rainwater or snow water is the best, river water is the second best. Well water is the second best, and water with minerals. Alkaline water is not suitable. If you need to use tap water, it is best to wait for one or two days for the chlorine contained in the water to evaporate before using it.

4. Watering orchids in hot season

The watering should done in the evening after the sun goes down, so that the water on the foliage will not be burned by the sun and the young part of the new shoots will not hurt by the high temperature water.

5. Orchid watering in the cold season

Watering should done during daytime to avoid frostbite of orchid roots at night in the pot. Avoid watering in the heart of the orchid, as it will make the young plant rotten.

6. Orchid plant leaves

When there is a disease spot, keep the leaf surface dry to prevent the spread of the disease.

7. Traditional cultivation substrate

It is best to adopt the “one dry, one wet” water management method, that is, water only when the topsoil is dry. A watering should watered thoroughly, until the bottom of the pot water, do not half dry and half wet. This alternating wet and dry water management is very beneficial to the growth of orchid roots. In winter, if there is no heat preservation equipment, less watering is appropriate.


E. Key points of orchid care during the flowering period

“If you want orchids to smell good, you should take good care of them. If the buds cannot protected, the fragrance of orchids will hopeless. This is the experience that orchid breeders have accumulated over the years, which is very valuable. So, how can we achieve “the fragrance of orchids is expected”? A: The key is to protect the flowers.

①The purpose of raising orchids

One is to see the color and appreciate the appearance, the other is to smell the fragrance, to achieve this purpose, the decisive goal is to see the flowers blooming during the flowering period.

②Most orchids

In the spring, the orchids that bloom in the spring come out in the fall. These orchids bloom on cold days, so the buds come out of the ground. Because of the high temperature, they stay put and wait for the opportunity to grow. This “opportunity” is the temperature drop, most of the season into the small snow, snow, small cold big cold. The buds then grow like a dream and become flower arrows and flower buds.

③ By the end of Lunar New Year

When the temperature drops to a low point around Chinese New Year, these orchids will have their fragrance.

④After the buds come out of the ground

Don’t turn over the pot to prevent the root system from damaging the nutrient transport channel and making the flowers bloom softly or lose color and fragrance.

F. Protecting orchid buds

1. Fertilizing orchids

Do not apply fertilizer to the growing area of the buds to prevent the effect of fertilizer from burning the flower stems and causing dead buds.

2. Replenish water to the potting soil

Don’t pour water down from the side of the bud to prevent the water from stagnating and causing the bud to rot at the base.

3. The buds grow long and row of bells

Do not spray foliar water on the buds to prevent impurities from accumulating in the buds and fermenting in the bracts and causing fatal damage.

4. Precious and famous

Orchid buds can covered with water moss, cotton, and harmless cardboard shells to prevent foreign objects and water quality infringement.

5. Before winter

3 days before winter, pour the last fertilizer (you can use the more widely available controlled release fertilizer), after winter, in principle, no watering or fertilizing. Because orchids are dormant in winter, they do not need water and fertilizer.

6. Winter watering

When there is a severe freeze, it is easy to freeze to death. Keep it dry to prevent frost damage.

7. After winter

Put the orchid in greenhouse, there is no greenhouse at home. You can put the orchids indoors where they are protected from wind and the temperature is better around 10℃, so as to ensure that the orchids can pass the winter safely. This will ensure that the orchids can safely survive the winter. The orchids can moved out of the house only in the 2nd year at the Ching Ming Festival.

8. Orchids in winter

You can choose a sunny day with no wind, from 9:00 am to 12:00 pm. Move the orchids to the balcony or the corner of the wall to get some sunshine to improve the cold resistance.

9. In orchid pots

When the soil is very dry, you can choose a sunny day and use a sprayer to spray some water slightly. If the soil is 80% dry, it is good for the growth of orchids. However, except for ink orchids, which bloom around Chinese New Year, the amount of watering should be more.
