Bulbophyllum
Introduction:
Bulbophyllum are the largest genus in the orchid
family with species deriving from the high and low
altitude rain and cloud forests of most tropical and
subtropical countries. They have remendous variation
in their growth habit, ranging from fully terrestrial
species to giant epiphytic climbers. They can bloom
directly from the rhizome or the growth, depending on
the species. Whilst it seems they are a diverse group of
plants, they can mostly be grown together. They are a
good genus to cultivate and relatively forgiving.

Cattleya
Introduction:
The following is a guideline for growing
orchids of the Cattleya alliance. Cattleya
and relatives are native to Central and
South American rainforests and are low to
high altitude, warm cultured (with some
notable exception as Cattleya dowiana,
some maxima, some rupicolous Laelia) or
lithotropic (grow on rock outcrops) orchids.
Cattleya generally have a pseudobulb with
either a singular thick leaf (unifoliate) or
two leaves (bifoliate) protruding from the
bulb. Flowers are singular or clustered,
large, bright and often scented. Unifoliate
Cattleya have thick leaves used for water
storage as well as the bulbs therefore these
plants can go considerable amounts of time
without water. Although there are many types within this alliance including cool, intermediate
and warm types, the guideline below gives a good idea of the methods in which to grow these
brilliant orchids. Following below will allow you to grow the hybrids, and many popular species.
Some notable differences will be mentioned such as Laelia anceps, as they are popular on their
own.

Cymbidium
Introduction:
The following is guideline for growing
Cymbidiums in Orchiata. It is aimed at helping
the grower to ensure that any areas of concern
have some guidance. It is important however
to remember that growing and climate
conditions will differ from greenhouse to
greenhouse and country to country. The guide
speaks of Cymbidiums in general although it is
well known that there are both heat and non
heat tolerant varieties as well as terrestrial
and epiphytic. From experience different. Cymbidiums will generally grow in similar
conditions although specific varieties will need
extra care.

Dendrobium
Introduction:
The following is a guideline for growing Dendrobium
commercial varieties of orchids in Orchiata and
Spagmoss; it is aimed at helping ensure that any
areas of concern have some guidance or referral.
There is also a quick guide available for ease of use.
Note that pot sizes and climate conditions will
change according to growers. Adjustments will have
to be made depending on their conditions; especially
for the different varieties grown. Remember this is
just a guide.

Disa
Introduction:
Native to South Africa, Disa orchids grow as a bog
plant on the outskirts of cool swamps. They are
naturally high altitude plants and prefer cooler
temperatures. Disa uniflora are the more common
types grown; flowers ranging in colour from bright
red to cool yellows on firm stalks good for cut
flowers. These plants are generally evergreen and
are easily grown from tubers. It must be noted that in
South Africa, it is a common practice to grow Disa
without the tuber stage, new growth being induced
shortly after the plant is blooming, and the tuber
stage being avoided. It is a technic that allows for
faster growth, but as well carries the risk of killing
the plant. As a result many cultivars from South
Africa have disappeared. In New Zealand or Europe
bulbs would be allowed to form which makes an
additional safety in case of culture problems. Today most of the older varieties are exceedingly rare or
even extinct due to a lower number of breeders still working commercially today. The new varieties are
still interesting but some colours and shapes no longer exist.

Epidendrum
Introduction:
This group of orchids encompass a range of plants which bear
colourful, long lasting flowers on top of vigorous growth.
Epidendrum are good novice orchid plants owing to their easy
growing habitat. Native to the Americas, they are variable in
habitat with some being lithotropic and some terrestrial. The
so-called ‘mini epidendrum’ are in fact hybrids of Epiphronitis
Veitchii, a very strange hybrid only made once that was
supposedly sterile. It appears that one individual plant out of a
tissue culture of that hybrid was fertile, which opened the door
to all the miniature Epidendrum used as pot plants today.

Masdevallia
Introduction:
Masdevallia orchids are a very colourful genus of orchids native to
South American countries such as Peru, Ecuador, Bolivia and Venezuela.
Their natural habitat is a cool cloud forest habit where the air is humid
and light is medium. They have beautiful delicate flowers ranging in
colour from whites, yellows, oranges to highlighter pinks and purples.
This group also encompasses the Dracula orchid which grows at even higher altitudes. Some species and even some cultivars of normally cold
species are able to grow at high temperatures such as some of the
Dracula vampira. It is not completely exact to say that they are cold growing plants; only that their roots need to be kept cold, in a way
similar to the Disa. In fact it can be explained in part by the dissolved
gases level in water where the maximal gas dissolution occurs at lower
temperatures and no gas can be dissolved at higher temperatures.

Miltonia and Miltoniopsis
Introduction:
Miltoniopsis orchids are native to the Andean and
Central American regions e.g. Peru. They are very
colourful orchids with flowers resembling large
pansies. Miltonia and Miltoniopsis can be
distinguished where Miltonia have 2 leaf Pseudobulbs
and Miltoniopsis has only one leaf per pseudobulb;
their cultivation can be treated the same however.
They are not the easiest of orchids to grow and are
therefore left for more enthusiastic growers. It may
be that their culture is poorly understood by some
growers.

Odontoglossum Alliance
Introduction:
The following is a guideline for
growing Odontoglossum and its
relatives. This group of orchids
include Oncidiums and other
genera native to the Central
American regions. The general
requirements for each genera are
the same however temperature
will differ generally due to the
difference in native altitudes.
Odontoglossum are usually native
to high altitudes in the Andes
where temperatures are much
lower. Oncidiums however are
native to lower altitudes down to
some coastal regions. Both these
plants grow all year round in all sorts of growing conditions and contain a variety of beautifully
coloured flowers, which are easy to grow in the proper conditions.

is also a quick guide available for ease of use. Note
that pot sizes and climate conditions will change
according to grower and that adjustments will have to
be made depending on these conditions, especially for

Vanda
Introduction:
Vanda are an interesting orchid which can be
grown without growing medium. Native to
the Himalayas, all through Asia, Australia,
and New Guinea; some of the most popular
species are epiphytic plants which grow on
various parts of trees. Vanda have very
robust aerial roots which extract moisture
from the atmosphere. These orchids are
grown for their stunning floral colour which
may occur throughout the year. Some
related genera such as the Mokara, and
Dimorphorchis however are partially
terrestrial and require much more wet
conditions at their roots. Bare root basked
culture is preferred as a convenience by most
growers; however stunning specimens have
been seen in pots.

Zygopetalum
Introduction:
Zygopetalum are a relatively easy
species to grow and can be treated
rather similarly to Cymbidiums
although damper conditions can be
tolerated. They are naturally epiphytic
or terrestrial with relatively sombre
coloured blooms – greens and purples.
Their main attractive feature is their
startlingly beautiful scent which means
they are sought after when in flower.
Most types have pseudobulb storage
organs which allow them to be divided.
