From processing plants before planting, watering regimes, fertilizing regimes and pest control.
1.1. Techniques to treat plants before planting
It is necessary to remove the old roots after taking them back (to limit the accumulation of water causing root rot). Next, use alcohol with concentration of 90 spray into the root cuts or use clear lime water and then hang it upside down to limit the penetration of pests into the plant. Then put the plant in a good environment and spray with moisture.
1.2. The technique of choosing the substrate
For orchids Hoang Thao Ken can be used for planting in pots, grafting wood. However, the wood grafting creates a higher aesthetic value.

Planting in pots must ensure that the stem is always facing the sky for long and heavy stems, then put them upside down like orchids like Phi Diep or Long tu or Hac Vy. The stump of the Hoang Thao Ken orchid, when planted, must be fixed and not shaken when moving the pot. Orchids are hung in well-ventilated places, not exposed to direct sunlight.
The wood grafting technique is similar to potting, but should not be grafted to the places where the wood has protrusions or indentations because they will cause rapid drainage or accumulation of water causing stem rot.
For Hoang Thao Ken orchids, if they have buds, they should not be grafted, but have to wait 2-3 days and hang upside down, do not water, do not use fertilizer. Remove the roots 1-2cm from the root before transplanting. In dry weather, water 2 times / week, in rainy days, do not water. Always maintain moisture for the root.
For flowering plants, it is recommended to cut off all the flowers so that the plant gives nutrients to nourish the base and mother stem (For plants that have not yet rooted).

1.6. Pest and disease prevention regime
For Hoang Thao Ken species in different seasons, there will be typical diseases in each season. In the summer, Lan will be susceptible to a number of diseases such as cone rot, yellow leaf rot, stump rot, and stem constriction due to the influence of weather conditions that are too sunny or rainy, making the plant more susceptible to disease.
In the rainy season, orchids often have constriction, and top rot due to heavy rains, usually in May to September. Dilute by ½ of the dosage on spray packaging with 2 times / month.
In heavy rainy seasons, you should put orchids hanging in well-ventilated areas, and avoid direct sunlight. In the cold season, the orchid resting period should see the tree atrophy, withered, water. After that time, add NPK fertilizer at the rate of 10-30-10 until buds appear.
