Basic knowledge of planting and taking care of Dendrobium

Choose a gardening location that must be well ventilated so that the environment is always humid and cool for the orchid to have more favorable conditions for growth. However, where there is ground, there can be orchids. Mainly to create sub-climatic conditions of orchid gardens such as water misting, paying more attention to watering to keep moisture ...

1. Make a net house to grow orchids

The direction of the orchid is very important. Make sure the garden has light and shade at all times.

Currently, there are black nylon mesh that dissipates heat and limits light widely sold, so it is very convenient, the spread does not need to be in the direction anymore, but depending on the position of the land, how to make the orchid.

Scaffold ribs: Scaffolding ribs need to be solid.

Standing pillars: Pillars must be planted with iron or concrete to ensure long-term, many horizontal and vertical trees to maintain. Pillars must be about 3-3.5m high.

Sunscreens: Use to shade direct sunlight. Usually made of nylon mesh, just stretch a few steel wires to make the mesh.

Hanging orchid truss: Used to hang orchids, this truss is best made of stainless steel or guarded by rafters, bamboo or round water pipes to hook the orchid pots. Suspension rig should be about 1.8m high to take care of not being entangled. Stainless steel trees or gong (water pipes, bamboo ...) must be guarded parallel, about 30 cm apart / tree. About 5 - 6 stinging sturgeon trees should leave a 0.6m wide path for convenient watering and care.

Hanging orchids must hang pots of the same length, orchid hooks are of the same length and planted at the same age, the same type of orchid for easy care, in a straight line to look new and beautiful.

Gantry hanging

Shelves for orchids: We can make shelves to spread. The 0.8 m high shelf has a hole that fits just like a pot, no need to spend hanging hooks and the middle of the frame; at the same time to have many pots.

Shelves for orchids

In addition, we can make beds for planting

2. Ecological requirement

Temperature: Dendrobium is suitable for a warm climate. The daytime temperature is about 27-320C, the night temperature is 16-180C. Low temperatures make the plant deciduous.

Light: Dendrobium orchids need light, the amount of light needs about 70% sunlight. Light is too high and leaves the plant burned. In case of lack of light, the plants are weak, thin leaves, small flowers and no flowers.

Humidity: Dendrobium needs 50-80% humidity

Ventilation: Choose a gardening location that must be well ventilated so that the environment is always humid and cool for orchids to have more favorable conditions for development. However, where there is ground, there can be orchids. Mainly to create sub-climatic conditions of orchid gardens such as water misting, paying more attention to watering to keep moisture ...

3. How to grow dendrobium orchids

Newly purchased dendrobium seedlings must be located in a well-ventilated location, and fungus control should be carried out prior to planting.

The planting medium is normally planted with wood charcoal, pine bark, palm tree, coir, brick ... But must be disinfected before planting. Common pots used are plastic pots or soil pin

Growing orchids in plastic pots

Planting method:

The most common way to grow Dendrobium today is potted. Plant the plant close to the pot edge and the direction of the shoot to grow inside. Plant tightly to not be shaken.

Planting on the trunk:

Can be planted on live or dead stems. For live plants during planting, pay attention to the canopy so that the light is suitable for the orchid being planted. For dead trees, choose the trees and then cut into chunks, then bundle the units to spread to the wood and care

4. How to take care

Watering: Watering helps maintain moisture during growth. The amount of watering depends on the stage of growth and development of the plant and depending on the season. Usually in the dry season, watering 2 times in the early morning and at 3 pm. watering the leaves and substrates

Fertilizing: Can temporarily split into 3 main phases to fertilize orchids:

a. Seedling stage: From tissue plants brought to nurseries to production gardens (about 4-6 months)

Some commonly used fertilizers:
Atonik uses 2-6 drops / liter of water
NPK 30-10-10 or NPK 30-15-10 use 0.5g-1g / l
Vitamin B1 used 1ml / liter

Spraying periodically 2 times / week, can use NPK in combination with vitamin B1 to irrigate baby orchids.

b. The stage of the production garden to the mature tree: this is the period of strongest growth

Some commonly used fertilizers:

Fish Feces Fish Emulsion 1ml / l
NPK 20-20-20 (1-1.5g / liter)
Vitamin B1 used 1ml / liter
NPK 30-15-10 use 1-1.5g / liter Spray periodically every 5 days.

How to use:

NPK 30-15-10 fertilizer combined with vitamin B1 spray 2 times / week. Spray continuously for 2-3 weeks; then spray 1 time of NPK 20-20-20; followed by spraying of fish feces. Then, repeat spraying fertilizer 30-15-10 and Vitamin B1 as from the beginning.

In addition, we can add fertilizer to the rootstock with Dynamic 5-7 lumps / root.

c. Stage plants prepare to flower and raise flowers:

This age is related to the seed formation process, flower quality and flower durability

Some fertilizers used:

NPK 20-20-20 (1-1.5g / liter)
Fish Feces Fish Emulsion 1ml / liter of water
Vitamin B1 used 1ml / liter
NPK 6-30-30 1g / l

Pest and disease prevention: Spraying room periodically every 7-10 days. Alternate use of different drugs.

Commonly used fungicides are Rhidomil, Aliette, Score, Vicarben

Pesticides: Decis, Bassa, B Thailand ...
