Warm Growing
15 - 28 C (60 - 82F)
Angraecum are warm growing and exotic orchids from Eastern Africa and
the island of Madagascar. They vary in size from around 6 inches to 36
inches high and have large leathery leaves spiraling around a central
tough stem (similar to Vanda). Typically the flowers are large,
showy and in the main white or ivory in colour, many are also fragrant.
Virtually all the Angraecum flowers have a large spur at the base of the
lip, this contains nectar to entice pollinating moths and other insects
to the flower.When growing on the Island of Madagascar these orchids would
be found in the deepest jungle growing along side and co inhabiting the
lush forests with Mantella frogs. Only recently discovered on island nothing
was know about these fabulously colourful and small jungle amphibians.
It is believed that some are as deadly poisonous as the Dendrobate or
Poison Arrow Frogs frogs of South America.Tropical Nepenthes
pitcher plants, commonly known as Monkey
Cups would also be growing in the warm and humid atmosphere of the
Madagascan forest with Hissing
Cockroaches scurrying around the forest floor.

Light requirements
Angraecum are epiphytic orchids and grow high up in trees where
they receive plenty of light, they should be given the maximum light
available which should be diffused to prevent scorching of the leaves
which are the food store for the plant. left: Angraecum

Watering requirements
Angraecums should be kept evenly moist at all times of year as they don't
have water storing bulbs. They should be watered at 7 to 10 day intervals
and sprayed with clean water daily from late spring through early autumn
and every 10 to 14 days at other times of year. They thrive on good humidity
so whenever possible you should damp down the greenhouse staging and paths
during the hottest months.
Feeding requirements
The plants are moderate feeders and a general purpose plant food can
be applied from April to September at 1/4 the pack recommendation, feed
these plants every third watering. Flush the pot or basket out once a
month with clean water to remove any unused plant food and salts which
can build up in the compost and harm the roots. During late August and
September you should water with a higher potash feed (again at 1/4
strength and every third watering) which will encourage the new leaves
to harden in readiness for the darker winter months. Feeding should cease
by late October and no more should be given until the following late winter
(Feb/Mar) at which time normal feeding can resume.
Re-potting schedule and Compost
Angraecum are naturally epiphytic and can be grown either in a pot, basket
or mounted on to bark. If planted in pots then large open grade compost
or bark with the addition of 1/4 sphagnum peat should be used to allow
swift drainage whilst holding moisture, in this case you should re pot
the plants every year or every other year depending on it's size, this
should be undertaken in spring as growth re starts. If grown in baskets
or on bark then re planting can be left for two to three years or until
they become unmanageable before being re planted.
