Cypripedium californicum

Starting in 1731, European - American scientists and herbs have just started studying orchids and sought to classify them according to criteria: growth conditions, reproduction, and shape. John Lindley was born in England in 1799, he went to many places to study orchids and left the world a set of books that could be said to be an extremely precious sutra, currently priced at $ 1200.

Orchids are popular because:

- The color is bright, full of looks, from clear as jade, white as ivory, silky smooth, smooth as chalk, dark purple, light red, brown, green, yellow, purple to dot, speckled, striped, There is no shortage of zigzagging.

Orchids have round wings, some kind of pointed wings, some kind of truncate, some kind of outstretched lines, some zigzags, wavy lines, some have beard, tangerine spout, there are flowers like butterfly, bee (Ophrys insectifera). Orchids have small flowers like the tip of a gout but also have Grammatophylum speciosum orchid dust in the Philippines that is nearly 10 meters high, about 2 meters long and weighs about a ton.

Orchids, if kept at the right temperature and humidity, can remain intact, intact from 2 weeks to two months, some up to 4 months, with things blooming year round, but also Type only 1-2 days has faded.

Many people find orchids often cling to branches, rocky cavities, so they think that orchids are a kind of mistletoe (Parasite), but in fact, orchids do not live on the sap of the tree. Lan just cling to it to live, absorb the natural essences carried by flowers, rotten leaves, bird droppings and other crystals transported by rain and wind.

People often mistakenly call all types of orchids orchids. But actually orchids grow in many places and are divided into the following 4 categories:

Epiphytes Orchids cling to branches or stems.
Terestrials Cymbidium grows underground.
Lithophytes Orchid agar grows in rocks.
Saprophytes Orchids grow on moss or rotting wood

Orchids grow in all five continents, four seas, from cold snowy regions to hot, arid deserts, from high mountains, deep forests to meadows of the plains and even wetlands. everywhere. Most orchids prefer to grow in tropical forests, especially in the Andes mountains of South America and the Himalayas of Asia. In these places, most of them are 3,000 feet to 7,000 feet high and the temperature varies from 50 to 90 ° F and every month it rains at least 3-4 inches of water.

Orchids belong to a large flower species with about 750 species and 30,000 primitive varieties and about a million have been artificially or artificially crossed, orchids (Orchidaceae) is a species of flowers in number 2 after the flower. chrysanthemum (Asteraceae). The reason we have to use the word roughly because nowadays, orchids are still growing in many places of deep paint and cup no one knows. Particularly in Vietnam, in the past decades, people have found some plants that have never been in the list of international orchids. They are Christensonia viêtnamica, Renanthera citrina, Paphiopedilum helenae, Paphiopedilum vietnamense and Paphiopedilum hiepii.

Calanthe Dorminii orchid is the first tree to be grafted in 1858, this type of Vietnamese name is Kieu orchid or rather called wine gourd orchid.

In the past, if you wanted to have orchids, you had to roll into deep forests and high mountains to find them. But starting in 1898 people have been successful in sowing and commercially flourishing since 1908. Usually other varieties have separate male and female flowers, but orchids have both male and female stamens. In a flower, except for a few like Catasetum etc. At first it was used by insects for pollination but then it was done within 1 minute and anyone could do it, except Some varieties are quite difficult. An average orchid has about a million small seeds and can be collected in different durations according to the variety. But when sowing seeds for seedlings, it is a pretty dreadful thing to disinfect, disinfect and germinate solutions for orchids. In 1960, French professor Georges Morel invented the Meristem method, which means cutting the sprout or spreading roots into small pieces and then placing them in a special solution, keeping on the machine while rotating and shaking. A few weeks later, this orchid will become a mass like silk, divided and planted into small orchids. At first, Professor Morel experimented with potatoes and dahlia flowers and then Cymbidium orchids. Then the scientists from Europe and America brought applications to other orchids. Vacherot orchid growers - Lecouffle in France is the first place to sell orchids cultivated by this method in 1964. Thanks to the Meristem method, many rare orchids are not extinct, but also because of that, the price of orchids is completely reduced. down.

Thanks to abundant facilities, abundant books, education, high technology, many amateurs today can also transplant orchids in the two ways mentioned above. Orchids grown by seeds, when flowering, each plant is a little different, but orchids made up of tissue culture are all the same as the mother plant. Growing orchids have now turned into an industry with an investment of up to tens of millions of dong. Every locality has orchid gardens, large ranging from 5-10 greenhouses to 30-40 acres, small from terraces to shaded gardens.

Orchids, the price is not too expensive, average 10-30 $ per pot, planting orchids does not take too much time, needing 10-15 minutes a week for 15-20 pots. Lan is not too difficult to grow and does not need to have green thumbs as many people think, just determination and attention to the points in the following tutorials are enough.

Stemming from passion, perseverance and hard work, after 23 years of research and research on orchid growing techniques, I have accumulated a lot of experience in propagating and cultivating forest orchids effectively.
