Orchids in water culture

orchids in water culture

You can place your orchid in any container with enough room for roots to grow, but it is fun to use glass so you can observe the progress of the plant. The container doesn’t need to be very deep but high curved sides can help support the plant and keep it from flopping over. Many hydroponic orchid growers also use clay pebbles in the bottom to help support roots and rise the crown from the moisture to prevent rot. The medium might seem to be straightforward – water – but there are good and bad types. Some municipalities treat their water until it is laden with chemicals and can be quite toxic to plants. A better route is using rainwater, or distilled. It is important to use tepid water to avoid shocking the plant.

Some growers simply leave their orchid in the water all the time with weekly or biweekly water changes. Others swear by soaking the orchid for 2 days and then allowing it to dry for 5 days.

one could set up most orchids to grow in water as long as there was oxygen exchanged. For instance, if the water was re-circulated or had a splash fountain or a bubbler we believe we could grow totally in water– as long as we keep the plant above the water and the roots in the water.

Catasetum Orchid

The Catasetum orchid genus has unisexual flowers, either male or female (they look different); which type appears is controlled by the lighting. If grown in low lighting like a Phalaenopsis, male flowers will appear; if grown in high lighting like a Cattleya they’ll have female flowers. The two flower types look different, so there will probably be one or the other that you’re looking for for the particular species you’re growing. (The male flowers are usually preferred, as they often have small, green, hooded female flowers.)

catasetum

For this particular family of orchids, after blooming occurs the plant goes into a dormancy/resting period where the leaves WILL YELLOW and DROP. This is completely normal. This resting period allows the plant to conserving its energy for the next growing cycle. Watering should also be reducing during dormancy.
Which type of flower a plant produces is determined by the conditions under which it grows. Male and female flowers are markedly different in size and color. At first, taxonomists even thought they were dealing with different species, a puzzle which Charles Darwin resolved when writing Fertilisation of Orchids. There are rare cases in which a single plant in intermediate conditions will produce both male and female flowers.
Many of these species are known to germinate in ant nests high in the canopy and host ant colonies, which provide the plants with an abundant supply of nitrogen, and they also host ants in cultivation frequently. Most of these species are considered moderately difficult to maintain in cultivation without a greenhouse or wardian case and some of them defy cultivation. Most of them cannot tolerate dryness and some of them have very specific temperature requirements. Some of these species are ant plants and attract ant colonies and can become a nuisance in cultivation.

‘Lou Sneary’

Neofinetia x Rhynchostylis = Neostylis (e.g. ‘Lou Sneary’)

Neofinetia falcata is arguably the first orchid ever to be grown as a house plant in Japan in the 1600’s. It is also known as the Samurai Orchid, as Shogun Tokugawa Ienari fell in love with the plant and it is rumored that samurai would help in searching and collecting the plants from the mountains. It is one of the world’s highest priced orchid (depending on the rarity of each variety), with a history of some plants selling for $100,000+. Neofinetias are enjoyed as bonsai are, for the foliage and the overall presentation of the plant. In Japan, it is said that the key to growing them is to enjoy the plant everyday of the year, not just for the flowers. They generally flower in June and July, and have a very sweet fragrance (somewhat like Jasmine) that is strongest at dusk and dawn.

Water
like to stay slightly wet between watering from late April until September or October, when the weather is warm and the days are long.If allow the moss to completely dry out in May or June, neofinetia often abort flowering for the season.During the cool season, only water or mist the plants on sunny days (if you have high humidity, you don’t need to do this often). these plants have a warm and wet growing season, and then a cool and dry season in Japan. We have found that the plants do not require a cool dry rest to grow and flower well.
Fertilizer

Fertilizing is important in the growing season only, which is from April until September/October. Fertilizer may be cut out 100% in the winter and when the plants are in bloom.
Temperature

Fuukiran are very strong plants, and are quite easy to grow. can tolerate temperatures from 0 to 37 degrees Celsius. Ideal temperatures would be 15 degrees Celsius at night, with a daytime temp in the mid 25 to 28 degrees Celsius
shade

They enjoy medium light conditions (no direct sun)
Repotting

Neofinetia can grow in almost any substrate as long as they get good moisture to the roots with good air flow. They can grow in sphagnum moss, bark, bare root in baskets (like Vandas if the humidity levels are high) and mounted on cork slabs.
Growing Outdoors

Semi-shaded with brighter morning sun will make these plants grow to their full potential. Being too cold and wet is often followed by bacterial or fungal rot. Also remember to keep the plant watered adequately as sun and wind will dry the plants out quickly.

Flower spike initiation in phalaenopsis.

What triggers or initiates spike growth on phalaenopsis is cool night temperatures of around 25 degree C for several weeks.A temperature of 32 degrees, even for a short time, will prevent spiking.
so my phalaenopsis plant grows quite well, but doesn’t bloom reason could be too high temperature. We find that phalaenopsis flower quite well at 16.5 degree C. If you are growing the plants indoors, artificial lights nearby might cause long days and thus inhibit flowering. If the plants seem to be growing well, water and fertilizer applied as directed, temperature ideal, and still no flowers, then not enough light is probably the answer. Gradually increase the light intensity . If growing in the home, move the plants to a nice, bright windowsill.

so What triggers or initiates spike growth on phals is cool night temperatures for several weeks. But, prior to this, it should have been growing and building up nutrient reserves within its leafs. This brings up a concern about how healthy the plant is, whether the leafs are full and firm (healthy) or somewhat limp and droopy (unhealthy).
other facts/methods

1)Some Phal species do not require temperature drop to initiate spike.

2)Timing these is very important for the cut flower industry. The nurseries that fill those markets grow their Phals in extremely dense shade–just a little more light than you’d get on a clear night with a full moon–for several months under tarps. When the tarps are removed and normal light levels restored, the plants spike within two weeks.
The darkness delays the normal spike season for the particular type of plant. In other words, if you have a Phal that normally spikes in December, and you want it to spike in March, you could drastically reduce light levels in mid November, then restore them in March to make the plant spike.

3) study points to the possibility of using intermittent high temperatures to prevent spiking. By applying cycles of 1 to 3 weeks of reduced temperatures (down to 59°F or 15°C) followed by 1 week of high temperature to inhibit spiking between late fall and early spring, it may lower the cost of inhibiting spiking by using constant 82°F (28°C).

Light

Oncidiums are more forgiving of bright, even direct, light than other popular orchids. They can cope with direct light in the morning and prefer bright or even very bright conditions. East, south or west facing windows are all suitable positions.

The leaves should be bright green as opposed to dark green or reddish green. Reddish green indicates too much light and dark green too little light.
Water

while watering allow the compost to become a little dry between waterings.They can withstand considerable drought because their large pseudobulbs act as stores. Wrinkled pseudobulbs generally indicate a lack of water. Black rotten roots are a sign of overwatering.

Temperature

Generally, the most popular oncidiums, with small yellow flowers, large pseudobulbs and strappy leaves, are those classed as intermediate to warm orchids. These require a minimum temperature ranging from 13°C to 25°C .
Humidity

Oncidiums enjoy moist air, requiring a minimum of 40-50% humidity in the immediate vicinity of the plant. Humidity should be increased with higher temperatures. The ideal humidity is 55-75%. Give as much ventilation or air movement as possible
Potting

Oncidiums do not like root disturbance and should only be repotted when either the compost becomes broken down or the pot becomes too small for the new growth. They like to be slightly under potted in a very free-draining bark-based potting media. As a general rule, repot when necessary. Every two years is ideal when the new growth is 5-7.5cm (2-3in) long.

Various Genera in the Oncidium Alliance includes

1)Brassidium “Brsdm.” (Brassia & Oncidium);
2)Oncidium “Onc.”;
3)Wilsonara “Wils.” (Cochlioda x Odontoglossum x Oncidium);
4)Odontocidium “Odcdm.” (Odontoglossum x Oncidium);
5)Odontonia “Odtna.” (Odontoglossum x Miltonia);
6)Miltassia “Mtssa.” (Miltonia x Brassia);
7)Colmanara “Colm.” (Miltonia x Oncidium x Odontoglossum);
8)Vuylstekeara “Vuyl.” (Cochlioda x Miltonia x Odontoglossum);
9)Miltonidium “Mtdm.” (Miltonia x Oncidium);
10) Burrageara “Burr.” (Cochlioda x Miltonia x Odontoglossum x Oncidium).

Spathoglottis

Common name for Spathoglottis is “Ground Orchids” even though there are several
other genera that can be planted directly in the ground as landscape plants. These orchids are terrestrials found in the tropics of Asia. Flowering should occur throughout the year on the most modern hybrids / clones since they were bred for more compact foliage and larger more colorful flowers.

Watering

Spathoglottis require good drainage in the media, so after a thorough watering allow the media to dry on top but you do not want the container to dry out altogether. Do not allow to sit in water.
Temperature

Spathoglottis are generally “warm” growing plants liking temperatures up to the high 30 ̊ C and they can tolerate temperatures down into the upper 15 ̊ C.
Potting media 

The plants are very forgiving as to the potting media. The mix should very free draining but holds more moisture than regular media for epiphytic orchids. Do not
bury the pseudobulbs.

Blooming

Blooms typically are produced when the pseudobulbs mature.

Rhynchostylis retusa (also called Foxtail Orchid)

Rhynchostylis retusa

Rhynchostylis retusa

The orchid has a bunch consisting of more than 100 pink-spotted white flowers.

In India, the plant is most common in North-East, Orissa and Andhra Pradesh.The plant is in the verge of extinction in India. Rhychostylis Retusa is recognized as the state flower of Arunachal Pradesh and Assam in India as well the Uva Province of Sri Lanka.

Rhynchostylis orchids grow epiphytically in the Asian rainforests on the lower parts of trees, unlike Vanda orchids, which grow on the tops.Rhynchostylis retusa, generally found in Assam in abundance
Care
Rhynchostylis orchids grow in shaded areas so they do not tolerate much direct sunlight unlike Vanda. In fact, they require bright indirect sunlight (something more than for Phalaenopsis but without a direct sun in midday). they are warm to hot growing orchids and don’t tolerate cool temperatures. It is a good idea to grow them bare-rooted without a substrate or in pure large bark in hanging baskets, just like Vanda orchids. They prefer humid air but they can tolerate somewhat dry air. Their roots look like as Vanda ones, but they are actually more tender and fragile, you should water them regularly but allow them to dry between watering, fertilizers should be applied in spring-winter months but not so abundant as for Vanda, because their growth rate is not so fast as Vanda’s.

Blooming

It normally bloom from fall to winter

Dendrobium Care

Shade

Required 50% shade.
Dendrobium can tolerate full morning sun followed by an afternoon of shade.
Watering

Daily in the morning. which we do in our condition ( kerala, india ) make sure medium is almost dry out between watering. Check the medium with your finger – if you feel moisture do not water.
Fertilizer

When your orchid is blooming, fertilizer is not needed. we using Green care 30:10:10 for small plants ( we used two times in a week) and Green Care – 13:27:27 for big plants. one time in a week.
humidity.

in very hot conditions it good to provide humidity by Humidity tray or some other means.
