1. Garden design:

- If growing for business, it is necessary to design a frame made of sturdy iron rails, to ensure durability and to resist wind storms. Light screens use gray or dark blue nets. Gantry placed iron pots, hanging trusses with long range or iron pipes. Planted goods should be designed perpendicular to the direction of the sun.

- If growing orchids to play on balustrades, awnings, terraces need to add other ornamental pots such as cau, apricot apricot, laurel . to reduce the hot dry due to the influence of concrete structures, corrugated iron . around.

2. Breed selection: There are many species:

- Species suitable for growing orchids are varieties: MoNaKa, Dendrobium, Phalaenopsis, Oncidium, Vanda, cattleya . are healthy, beautiful and durable plants, giving flowers continuously. Should be planted with many types, many colors will be easily consumed in the market.

- If growing orchids to play, entertainment should be planted Dendrobium, female Vu, Lake messages because these are easy to care and flowering species.

- Growing orchids can propagate by tissue culture or germ separation, choose to separate germs from large orchids, each part to 2-3 branches. Using a sharp knife to disinfect with alcohol, cut it neatly, after cutting, apply lime to the cut to heal scars quickly.

3. Preparation of substrates and pots: The growing medium for orchids can use wood charcoal, coconut fiber, peanut shells.

+ Wood charcoal burning song, size 1 x 2 x 3cm, soaking, washing, drying.

+ Coconut fiber to soak for about 1 week to reduce tamin and salty, dry. Acne coconuts need to be washed and dried. Coconuts are chopped into 1 x 2x3cm 5% lime water.

+ Peanut shell: Use a spray hose several times to remove some impurities, reduce heat, oil, then peanut shells into plastic or earthenware pots, size depending on type and age. If planted on beds, put peanut shell into 20cm thick bed. If you grow your business, you can use peanut shells to be cheaper. In addition, peanut shell absorbs less water, moderate moisture, spread less fungus.

4. How to plant:

- Planting on beds: Making beds 80cm wide, depending on the size of the soil, giving peanut shells 20cm thick. Two ends of the bed can use concrete columns or iron columns to stretch cables, each bed needs 3 rows of small cables on the horizontal bar to locate the orchids. Can adjust the height of the cable according to the development of orchids.

- If using tissue culture spread, when the tissue spread is about 4cm, it should be moved out. The tissue is washed away to put on a net or basket in the water basin to keep the seedling cool. The period of planting together on the bundle of coconut coir around the orchid tissue culture, using elastic band and then put it on the rig. After planting on rigs for 6-7 months, transfer to small pots. About 6 months then transferred to larger pots. After each transfer of pots for about 1 week new fertilizer. Repotting also depends on the size of the tree, the level of rotten, damaged moss .

* Note: Lan grows in pots for a long time, flowers need to be removed and spread out of the pot, cut old and too long roots, transferred to a new pot, replace the new substrate, the orchid will grow well and flower again .

5. Care:

Lan is an easy-to-care crop, if we ensure favorable conditions for growing orchids. The most important factors for spread are light, irrigation water, moisture, pots or substrates and nutrition.

- Light: Lan does not tolerate strong light, it is necessary to make a net cover to protect the light, when planting, it is necessary to cover two layers of mesh Light about 65 - 70% is best. After planting, always water (always sprinkler) and maintain 2 times / day. 3 days after planting, watering vitamin B1, mixing 1cc / liter to stimulate root development. After 7 days watering NPK fertilizer 30-10-10, dosage of 5-10g mixed into 8 liter bottle to spray. When new plants sprout, the roots of the tree grow more and increase the amount of fertilizer.

- Fertilizer: Lan needs fertilizer but cannot tolerate high nutrient concentration, so fertilizing for orchids must be done regularly and preferably by spraying through leaves. Fertilizers for orchids must contain adequate nutrients, medium and micro-nutrients with ingredients and proportions suitable to each period of plant growth and development. The general principle is that spread during growth of strong leaf stems requires high nitrogen, low phosphorus and potassium, before flowering need high phosphorus and potassium, low nitrogen while flowering orchids need high potassium, phosphorus and nitrogen lower. Fertilizer suitable for these periods is 501, 701 and 901 Buffalo Head, this is a full and balanced fertilizer of multi, medium, micro and growth regulators. Concentration and dosage depend on age and development period.

- Watering: Lan needs water for growth and development. If there is a lack of water the plant will wither, pseudo-pseudobulbs, leaves fall but not die. Excessive water, plants are prone to rot especially with orchids with vertical leaves growing together. Too much root water has strong growth of algae and fungi. Water for orchids is not too salty, alum and clor are below the permitted level, pH 5.6. Just water enough moisture, so water in the early morning or late afternoon, avoid watering in the afternoon when it is hot. After irregular rains, especially the first rain of the season, irrigate immediately to wash down the residue on the leaf stems.

- Pest and disease prevention: Lan is a plant that is susceptible to pests and diseases, especially in poor conditions of care and unfavorable environmental conditions. Depending on the type of pest, use appropriate medicines. The dosage and spraying concentration should follow the instructions on the product packaging. If spread with leaf-leaf pests, drugs containing Fenitrothion, Trichlorfon such as Ofatox 400EC and Cartap active ingredients such as Patox 95SP or Capafaf, Capan or Actara 25WG can be used. Lan has aphids, white aphids, aphids using Supracid 40ED / ND, Suprathion 40EC, Bitox 40EC or Ofatox 400EC. Spreads are caused by fungi, bacteria or viruses causing the blight of the leaves, the spread spread gradually, the root rot used Zinep, Starner 20 WP or Benomyl.

6. Flower harvesting and preservation:

Cut branches soaked in solution about 15 minutes to help the flowers wither, then wrap them with newspaper.
