Let's introduce the planting method of Phnom Penh orchid:

1. Soil requirements

Phnom Penh has strong adaptability, does not choose soil, is more drought-resistant, but not cold-resistant, and is not demanding on soil, and generally grows better in well-drained, loose and fertile sandy soil. Generally, we can choose Dvordo organic nutrient soil. If the air permeability and water permeability of the basin soil are poor, the water accumulation of the basin soil is not dry for a long time, and it is difficult for the root system to breathe, which leads to the yellowing of the leaves, the soil should be loosened and the moisture should be controlled in time.

2. Cuttage propagation

Phnom Penh Cymbidium can be propagated by cutting, ramet, sowing and other methods, mainly by cutting propagation, which can be carried out at any time from spring to autumn. Cut the clustered stems and leaves on the stolon of Cymbidium (in fact, it is a new plant larva, with leaves on the top and air roots at the bottom), plant it directly into a flowerpot and keep it in the shade. Be careful not to bury it too deep when cutting, otherwise it is easy to break your heart.

3. Lighting requirements

Phnom Penh orchids like semi-shady environment, spring and autumn should avoid strong direct sunlight, summer sun is particularly strong, can only see some oblique light in the morning and evening, during the day need to cover 50% of the sun's 70%, otherwise it will make leaf tips dry, especially flower and leaf varieties, more afraid of strong sunlight, Phnom Penh orchids grow more beautiful in places with weak light, yellow Phnom Penh orchids are more obvious, leaves are brighter. But it should be more sunny in winter in order to keep the leaves tender and fresh green.

4. Temperature control

Phnom Penh likes warm and humid climate and is afraid of cold and high temperature. it grows fastest at 25 ℃, stops growing above 30 ℃ and below 0 ℃, and its leaves are easy to turn yellow and dry. In winter, when the room temperature is more than 12 ℃, the plant can grow normally, draw leaves and blossom; if the temperature is too low, it will grow slowly or dormant; if it is lower than 5 ℃, it is prone to cold injury.

5. Watering method

Phnom Penh orchids like a humid environment, and the basin soil is easy to keep wet. Summer watering should be adequate, around noon and evening should also spray water on the branches and leaves, timely cleaning the dust on the leaves to prevent the leaves from drying up. Specific methods can refer to the main menu → novice planting → watering method → teach you the correct watering method. However, the fleshy roots of Phnom Penh can store a lot of water, so they have a strong ability to resist drought and will not dry to death without watering for several days. Under 5 ℃ in winter, less watering, basin soil should not be too wet, otherwise the leaves will be easy to yellowing.

6. Fertilization method

Phnom Penh is a more fertilizer-tolerant foliage plant, if the lack of fertilizer and water, it is easy to scorch head aging, leaves yellowing, loss of ornamental value. From late spring to early autumn, Devodo series liquid fertilizers with a proportion of 300% can be applied every 7-10 days, but less nitrogen fertilizer should be applied to Phnom Penh orchids, Jinxin and other flower and leaf varieties, so as not to fade or even disappear, affecting their appearance. Devodor bio-organic fertilizer granules can be properly applied. Stop fertilizing when the ambient temperature is below 4 ℃. Pay attention to the frequent application of thin fertilizer, fertilizing too much, exceeding the needs of the plant. At the beginning, the leaves are shiny and uneven, after the roots rot, the leaves will be yellow. Should stop fertilizing, irrigate more water, or turn the pot to clean the root and replace the new soil.

7. Turn the basin and change the soil

In the management of potted Phnom Penh orchids, in order to have luxuriant stems and leaves, the soil and pot should be changed once in March every year. If the basin is deeper and the base fertilizer is more sufficient, the basin can be changed once every two years. When turning the basin, knock the plant out of the basin, cut off the withered roots and excess roots, replace it with the new Dvordo organic nutrient soil, and then apply the Dvordo bio-organic fertilizer as the base fertilizer. After planting, put the seedlings in a warm and semi-overcast place.

8. Pruning method

The general height is not to meet, and should pay attention to ventilation. The lower withered leaves and yellow leaves should be picked at any time, and the yellow head should be cut off obliquely with scissors when the leaf tip is yellow. Cutting off some of the old leaves of Phnom Penh in the first and middle of May will promote the germination of more new leaves and small Phnom Penh.

A little knowledge:
