Orchids are either species or hybrids.


Species are denoted by two Latin words in italics, the first denotes the genus and the first letter only is capitalized, the second denotes the species, and is completely lowercase. It is often a descriptive term, example: Cattleya violacea or a Latinized version of its discoverer, example: Cattleya skinneri for Georges Ure Skinner.


Hybrids are designated by two species or hybrid names, separated by an "X" example: Phalaenopsis Cassandra X aphrodite. If the cross has been registered with the RHS (Royal Horticultural Society), it has a name, for example Phalaenopsis Timothy Christopher. The name of the hybrid is composed of the name of the genus (always in italics, and 1st letter in capitals), and of its cross name, which is not in italics, and each word of which begins with a capital letter.


Note that the name is sometimes followed by a cultivar name and / or an acronym meaning that the plant has won an award, for example AM ​​/ AOS.


Sequoia bark medium size .... 70%

New Zealand sphagnum moss .... 10%

Perlite .... 10%

Charcoal .... 10% (if available)


Note that for Paphiopedilum and Phragmipedium, we can increase the proportion of foam and decrease that of perlite. For small plants, or those with fine roots, it is best to use bark of small grain size. Depending on the growth of the plant, repot every two or three years (The roots of Paphiopedilum and Phragmipedium must not be discovered).


If you are buying unpotted orchids, i.e. bare roots, here is how to proceed:


Completely submerge the plant in a solution of lukewarm water with sugar (one teaspoon for one liter) for a period of 3 to 5 hours. Subsequently, temporarily pot it in damp moss (New Zealand sphagnum moss), in the shade (subdued light) for a week; then we can pot as usual.



If your plants have been outside during the summer, they should be treated before bringing them in. We should immerse the pots in an insecticide solution and spray the foliage with the same solution, once a week for three weeks. The next morning of the third week we can bring in the plants.

Insecticide solution recipe

200 ml of garlic oil (see recipe below)

20 ml of Neem oil

a few drops of eucalyptus oil

45 ml of dish soap

4 liters of water

Garlic oil recipe

3 heads of garlic, chopped in 60 ml of vegetable oil; let macerate for 24 hours at room temperature.

Pass through a sieve then add 1 liter of soapy water (10 ml of dish soap / 1 L of water)


(1) INITIATION OF FLOWERING (for Phalaenopsis)

For a period of 6 weeks:

Increase the daytime temperature by 5 ° C and decrease the nighttime temperature by 5 ° C

Increase lighting by 25 - 40%

Space the waterings.

No fertilization.

Reduce ambient humidity.


For a second flowering on the same stem: cut the flower stem just above the last dormant bud below the first (wilted) flower. There will be a branching with new flowers. The only restriction is to ensure that the plant is mature (more than two leaves).



All windows except those facing due north, ideally south-east or south-west. Cool white neon lights are good substitutes as long as the orchids are placed very close (about 4 inches, 10cm). A high pressure sodium lamp is the artificial lighting of choice.


Many orchidophiles use deionized water (reverse osmosis filtered) or rainwater, or tap water can also be used at room temperature.



For small quantities of plants, you can use small polyurethane or enameled metal containers in which you put aquarium gravel and water, but so that the pots do not touch the water. For a larger number of plants, we can build a shelter (a tent) in polythene in which we put a humidifier and a ventilator.
